Neon Web Based Technology Overview

Unidata provides a range of Internet

Protocol Telemetry data loggers (Neon

Products) and associated Neon

Server Applications Software facilitate

transport of data from the measuring

instruments in the field to a central office.

In this section we provide some

background to Internet Protocol (IP)

telemetry and some rational as to why

this is a growing method of providing

connection between loggers in the field

and central offices.

Telemetry systems have been used

extensively for successfully transporting

data from field measurement devices

to central computer systems for many

years. With the growth of the internet

and telecommunications networks

there are now more options available

for telemetry.

Pull and Push TelemetryIn past years data was recorded from

field instruments with chart recorders

and the charts were collected from

the field and brought into the office

for analysis. In the 1970’s data

loggers came into wide usage and

data was recorded in the memory of

loggers which were brought back to

the office to download the recorded

data from them for analysis, or the

data was downloaded into portable

computers in the field which were

then brought back to the office for

analysis. Soon after fixed phone lines

at the measurement site and dial up

modems were used to allow the office

to dial up the data logger in the field

and download the data via the fixed

line phone system, and this was the

first real uptake of telemetry, which was

initially pull telemetry or connection

oriented telemetry, where a dedicated

connection was needed

Dial up telemetry also expanded with

the introduction of mobile phones and

satellite phones however a modem was

still used so the basic method did not

change. The transaction still required

a manual or semi automatic or fully

automatic system of establishing a

circuit (either landline, mobile phone

line or satellite line first, and then using

a modem to transfer data via a circuit

Neon Server Features:

• View data from any browser on the internet

• Reconfigure Neon remote loggers on-line

• Diagnose and reset Neon remote loggers on-line

• Upload new logger schemes on-line

• Automated FTP/ Web Services/email reports

• Automated email and SMS alarm notifications

• True IP services/guaranteed data delivery system

• Industry standard microsoft.net architecture

Typical Applications:

• Remote data monitoring and acquisition

• Environmental compliance reporting

• Metering for utilities

• Asset monitoring

which was primarily designed as a voice

circuit. The main principle here is that

a new circuit needed to be established

for each transfer or each modem. There

were also some “leased lines” used,

whereby a permanent circuit was set

up for such transfers, but the principles

remained the same.

With the arrival of the internet and the

wide use of TCP/IP data a new method

was possible, whereby shared packet

networks could be used to transfer

data from the field to the office by

sending the data in packets across

shared TCP/IP networks. There are

both private and public IP networks,

and telecommunications providers use

other technologies within their networks,

such as frame relay and asynchronous

transfer (ATM) to transport TCP/IP

packets however from a user’s point of

view it remains a TCP/IP network from

end to end. With a packet network many

users can send packets across the

same network at the same time and the

sending end initiates the transfer, hence

this type of telemetry is called push

telemetry or connectionless telemetry,

where a dedicated connection is not

needed for each transfer. Another

method of push telemetry is SMS

or other short message services

where a simple text message is sent

across a shared network. Most SMS

or short message services are not

guaranteed delivery methods and

this is an important consideration for

telemetry applications. With the TCP/

IP method each packet is sent, and an

acknowledgement for that packet is

requested and if not acknowledged, the

packet will be resent, thereby ensuring

data packet delivery. With SMS type

messages there is generally no such

acknowledgement method built into

the system and messages may be

lost. Message loss is unusual, but it is

still possible and therefore SMS type

messages are not a guaranteed delivery

method hence such methods are less

desirable than true TCP/IP methods.

To balance this argument, SMS type

messages may be less expensive and

they need to be considered in the mix of

services available.

Mobile Phone / Cellular Phone NetworksIn times past, each home had a phone

line which was fixed at the house or

office, i.e. it was location centric and

many users in that home or office

used that service. Now we see the

decline of these fixed phones and the

networks are now mobile or person

centric. Telecommunications providers

are now expanding such networks to

provide more services across mobile

phone / cellular phone services and

the expansion is by adding services,

such as SMS messaging, and internet

connection services. The growth is

in speed of internet connection, (G3/

HSPDA etc) and this speed increase is

interesting but not especially relevant

to telemetry as the current lower speed

GPRS (General Packet Radio Service)

type services are generally as fast as

the telemetry application needs are

today and will be into the future.

Mobile Phone / Cellular phone networks

using GPRS services seem an ideal fit

for push telemetry however there is one

design aspect which is very relevant

to telemetry applications. These

networks growth is generally related to

population growth, with most providers

advertising they have 90% of the

population covered by their networks.

However most of the population is in

the large cities where infrastructure can

be shared across many users, thereby

making it economic for the provider to

install new base stations. Generally

telemetry is needed in remote areas

and this is where there are few people

and where providers do not want to

install base stations as they cannot

amortise the cost across enough users

to make the system economic. Hence

while 90% of the population may be

covered by such networks, perhaps

only 50% of the country area is covered

by the network.

Regardless of this, Mobile Phone /

Cellular phone networks will always

offer the most economic method of

communication in more than 50% of

the land area and there will usually be

a very good economic benefit when

utilising these networks in a telemetry

system. It is also interesting to note

that in developed countries such as

Australia, where fixed line phones

have been widely installed the need for

Mobile Phone / Cellular phone networks

is not as important than in developing

countries where there is little fixed line

phone infrastructure, for example in

India and Thailand. In such countries

Mobile Phone / Cellular phone network

coverage in remote areas is probably

a lot better than Australia as they

don’t have as much fixed line phone

coverage.

Also, as the data needs of telemetry

systems are relatively small, the lower

speed GPRS services are the most

likely services appropriate to telemetry

applications.

Satellite ServicesSome of the history of satellite services

is detailed here for general background.

Commercial satellite communications

services started in the late 1960s / early

1970s primarily as undersea cable

technology could not keep up with the

growth need for international circuits.

As analogue undersea and land based

coaxial cables were limited in capacity

(to around 1000 voice circuits per cable)

satellite circuits offered an immediate

and economic capacity increase and

offered a good commercial offering for

circuits. When fibre optic cables were

developed in the 1980s, and these

cables offered much larger capacity

(to around 250,000 voice circuits for

a similar cost) they became a much

better alternative to satellite circuits

for major demand. However Satellite

technology offered and still offers some

unique benefits of wide / global coverage

especially in areas where there is limited

infrastructure albeit at a higher cost.

Technology Considerations for Satellite CommunicationsThere are two main types of satellite

services, equatorial orbit satellites and

low earth orbit satellites. The diagram

below shows in diagrammatic for such

services.

Equatorial satellites orbit the earth at

the same speed as the earth rotates;

hence they appear to be stationary to

a user on the earth’s surface. These

satellites are at a height of around

25000 km above the earth’s surface

and act as a stationary radio repeater,

receiving microwave signals transmitted

from the earth, amplifying them and

changing their frequency and re

transmitting them back to earth usually

using focused antennas which point to

the required area of coverage.

The focused antennas are called spot

beams. There are some satellites which

have wider beams, called global beams

and these provide wider coverage with

less power in a given coverage area.

Satellite Control & Management Ground Station

Low earth orbit (LEO) satellites orbit

the earth within an hour or two and

cover a smaller area which is only

visible during the time when they are

overhead, within view of the user on the

earth. They are at a height of around

1000 km above the earth’s surface

and there are generally 20 or more

satellites in any LEO system and on

average there will be at least one to 4

satellites in view to use at any one time. 3

Satellite communications frequencies

are specified in bands, for example

KU band (around 20 GHz Hz), C Band

(around 5 GHz) and L Band (around 1.5

GHz). As the frequencies are different

the loss in different atmospheric

conditions needs to be considered. KU

band in particular suffers high signal

loss in heavy cloud and rain. Antenna

size also needs to be considered. As a

general rule the smaller the frequency

the smaller the antenna. Generally

L Band downlink has been more

widely used for mobile or semi mobile

communications as it does not suffer

much rain fade and the small antenna

size on the earth based receiver is

more convenient. Some satellite data

providers use two frequencies, an

uplink from the earth to the satellite

from a central location on the earth and

a different downlink frequency from the

satellite to the earth.

Satellite communications delay or

latency is another very important

consideration. Radio signals

travel at about the speed of light,

and the transmission delay for an

equatorial satellite is typically 250ms

(milliseconds), or a quarter of a

second. The transmission delay for a

comparable LEO Satellite is 25 times

less as it is 25 times closer to the earth.

While this delay does not seem much,

there are important considerations

when using packet based services,

especially when packets are sent

and acknowledged as part of the

transmission system.

Satellite power is expensive and

systems are designed to allow effective

communications within a small

calculated link margin. Link margins

are calculated based on free space

loss from the satellite to the earth and

other factors, such as transmission

speed and bandwidth. The commercial

consideration is to ensure the satellite

provider provides a reasonable link

margin, or margin for error above the

minimum power required to operate

the system. For fixed installations, link

margins are generally very small, but

for mobile satellite systems, where the

antenna may be moved, received signal

levels can vary widely and a higher link

margin is required.

Satellite availability for equatorial

satellites is straight forward. If the

satellite is in the correct orbit then

it should be always available. For

equatorial satellites the provider

needs to have a backup or redundant

satellite available. In the event of a

failure of the primary satellite and the

availability of the backup, as well as

the time to switch to the redundant

satellite needs to be specified.

Satellite availability for LEO satellites

is different, as there may be 20

or more satellites available at any

one time. For LEO satellites, the

satellite provider needs to specify

the availability in minutes to acquire

a satellite and the minimum number

of working satellites it will provide

over a given period and their plans

and actions if more than one or

two satellites in the system fail.

Generally LEO systems can tolerate

the failure of 1 or 2 satellites without

much degradation of service. If 4

or 5 satellites failed there may be

a problem, with extended times to

acquire a satellite.

Technology Comparisons- TCP / IP versus Short Message Service OfferingsSatellite data service offerings are

either true TCP/IP services or short

message services. Some discussion

in regard to these services is needed

for comparison.

TCP/IP services are standard and do

not require further comment, other

than the fact that only a few offerings

are appropriate for TCP/IP services.

Latency / delay is the most important

consideration for such services and

any equatorial service will struggle to

offer good end to end TCP/IP services

as the latency is high for equatorial

services.

Short service messages offered

by LEO satellite providers allow

the operator to deal with the earth

to satellite and inter satellite hop

and satellite to earth delays. Some

LEO satellite providers consolidate

messages to reduce cost which also

adds to the latency/delay.

For communications to occur one of

these satellites needs to be acquired

communications established and the

call or data transfer to be completed in

10 to 20 minutes while the satellite is in

view overhead.

Some systems can effectively transfer

the call or data transfer to another

satellite automatically as indicated in

the diagram below.

The LEO systems are analogous to a

set of orbiting mobile phone / cellular

phone system base stations.

As a general rule equatorial satellites

require more power and are more

expensive per call than a LEO satellite

system. Also as the equatorial satellite

does not move in relation to a user on

the earth, they are always available

immediately.

There are four other important aspects

of the technology discussion in regard

to satellite communications, satellite

communications frequency, satellite

transmission delay, and satellite power

and satellite availability.4

Neon Camera System and Module

Model 2502A

The 2502A Neon Camera System is

a Neon Camera Module interfaced to

a Neon Remote Module all housed

within a rugged security camera case,

which can be mechanically adjusted to

the required image view. The system

has lithium battery power for both the

camera and the Neon Remote Module

so it can operate as a stand alone

system without the need for external

wiring or external power.

Alternatively the 2502A Neon Camera

Module can be supplied as a stand

alone component to be connected to

an existing Neon remote Terminal or

Module. The Neon Remote Terminal

or Module can be programmed to

send a ‘take picture’ command to the

camera either routinely based on a fixed

schedule or on demand.

The camera electronics will take the

picture and return the image to the

Neon Remote Terminal or Module which

will then upload the image to a Neon

Server.

The view / focus / initial setup of the

camera can be performed on site using

a laptop computer and companion

camera software. This process sets up

the actual view needed on site.

Once these initial view parameters are

set, the camera will take a picture of

the required view when requested to

do so by the Neon Remote Terminal or

Module.

Typical set up configurations include:

- daily picture taken and the image

sent to Neon Server as a record of

the site each day

- on demand picture taken and image

sent at any time when requested

by the Neon Server if there is an

unusual event or activity at the site

The Neon Server Applications Software

has the facility to view, store and recall

images in a similar way it does for

logged data.

Neon High Resolution Image and Video Camera System

Model 2502B

This is Unidata’s high resolution Neon

Camera system which can be set up to

take still images in a range of resolutions

and can also take video snapshots and

display those images and video captures

and send them to a central neon Server.

The images and video snapshots can

be displayed on any web browser on the

Internet, as well as being sent routinely

by FTP to a further system for display

and archive purposes.

The system uses the Inmarsat M2M

service as the bandwidth requirements

are high. It supports video, with the

ability to capture an immediate or

scheduled high resolution image and an

immediate video capture for a defined

period, from 1 to 5 minutes, and to set

up a suitable frame rate and resolution.

For most applications a slower frame

rate of 5 frames per second, similar

to security camera frame rates will

provide a reasonable video performance

reducing the bandwidth requirements.

The Neon Applications Software

maintains the hi res and video files in

the same SQL database and these can

be viewed on the web interface and or

reported out of the neon system in the

same way data logging files are reported

out. For example by ftp, email and web

services or by direct SQL database

access.

how the resolution and frame rate and

encoding can be selected via the web

interface at a central location, while the

equipment is located at the very remote

location.

Multiple camera buttons may be added

so that different resolution images

and videos may be captured from

the same camera without the need to

reconfigure the camera. Simply press

the appropriate capture button to take

a photograph or video at the required

resolution or frame rate.

Photographs and captured videos

may be viewed on the photographs

The Wind Monitor is a high performance

wind speed and direction sensor

manufactured by R.M. Young Company

and designed specifically for air quality

measurements. It combines simplicity

and lightweight corrosion resistant

construction with a low threshold, fast

response, and excellent fidelity.

The wind speed sensor is a four blade

helicoid propeller. Propeller rotation

produces a sinewave voltage output

where frequency is directly proportional

to wind speed. Slip rings and brushes

are not used.

The wind direction sensor is a

lightweight vane with sufficiently high

damping ratio and low aspect ratio

to ensure excellent fidelity in rapidly

fluctuating winds. Vane position is

sensed by a precision conductive

plastic potentiometer. With a known

excitation voltage applied to the

potentiometer, the output signal is

directly proportional to azimuth.

The instrument is made of UV stabilised

plastic with stainless steel and anodised

aluminium fittings. All bearings are

precision grade stainless steel.

A micro-power interface circuit, housed

in a junction box on the mounting post,

converts the sinewave to a 5V signal

and potentiometer output to a calibrated

2.50 V signal, suitable for connection to

the data logger.

An 8 core cable (Model 6600F) can

be used to connect the instrument to

the logger. The instrument mounts on

standard 1 inch pipe.

precipitation, temperature, and wind

speed and direction - all with one

instrument! Compact and lightweight,

the 6501V is suitable for weather

stations, dense networks, buildings,

golf courses, marinas, harbors, and

hotels - almost anywhere where real

time weather data is needed. Accurate

and reliable data provided to you early

enough can increase safety to life and

property.

To measure wind speed and direction,

the 6501V has the Vaisala WINDCAP®

sensor that uses ultrasound to

determine horizontal wind speed

and direction. The array of three

equally spaced transducers on a

horizontal plane is a Vaisala specific

design, which ensures accurate wind

measurement from any horizontal

wind direction without blind angles

and corrupted readings. Barometric

pressure, temperature, and humidity

measurements are combined in

the PTU module using capacitive

measurement for each parameter. It is

easy to change the module without any

contact with the sensors. Precipitation

measurement is based on the Vaisala

RAINCAP® sensor.

Water Monitoring Instruments

The Ultrasonic Doppler Instrument is

a compact, easy-to-use system for

measuring the velocity and depth of

water in drainage channels, large pipes,

and in rivers and streams.

It is suitable for use in a wide range

of water qualities, from sewerage

and waste water to clean streams,

potable water, and even sea water.

The instrument measures forward and

reverse flow conditions and may be

programmed to compute Flow Rate and

Total Flow in pipes and open channels.

The Model 6526H combines an

ultrasonic transducer assembly (profiled

to reduce flow disturbance) with signal

processing electronics. It is designed

to be placed at (or near) the bottom of

a water channel for “upward looking”

measurement. A single cable connects

the instrument to a 12VDC power

source.

Water velocity is measured by the

ultrasonic Doppler principle which

relies on suspended particles or small

air bubbles in the water to reflect

the ultrasonic detector signal. The

instrument will not operate in very

clean, “de-gassed” water. Water depth

is gauged by a hydrostatic pressure

sensor, referenced to atmospheric

pressure through the vented power and

signal cable.

Water temperature is also measured

so the instrument can adjust for the

change in velocity due to speed of

sound. Water temperature can also

be logged.

This interface converts a serial signal

to a 4-20mA output. Any MicroWire

compatible 3-wire synchronous serial

signal channel can be used as an

input. It supports two 16-bit resolution

channels.

The Starflow, Prologger and Starlogger

support MicroWire as an alternative use

of the SDI-12 channel. This enables the

connection of any measured channel to

a 4-20mA transmitter.

The Model 6541 Precision Water Level

instrument can achieve operating

accuracy and resolution of 0.2mm. This

accuracy is maintained for the service

life of the instrument without calibration

or maintenance, apart from battery

changes.

This instrument has the range to

monitor surface and underground

waters, and the precision to monitor

rainfall and evaporation.

The instrument is normally connected to

the water surface by a float system. As

the water level changes, the input shaft

rotates. An optical encoder is mounted

on the input shaft. On installation, the

instrument is set to display the water

level.

The encoder is continuously monitored

as the instrument tracks water level

changes. These changes update the

LCD display and the readings can be

recorded by an associated data logger.

The very low mechanical friction and

inertia of the instrument mean that it

can produce data with high precision

and accuracy. A replaceable battery

pack powers the instrument for more

than six months. A practical design

and rugged construction ensure easy

operation and long service life.

The 6541 Precision Water Level

Instrument is available in a number of

models. The key differentiating features

are the:

• Presenceorabsenceofa

Micrologger assembly.

• Presenceorabsenceofaninternal

pressure sensor to be immersed down

to a depth of 100m. The inner vented

connection cable makes pressure

compensation of the measuring cell

against the atmosphere possible

and thus hydrostatic pressure

measurement. The pressure sensor

special for submersible measurement

meets the electromagnetic compatibility

(EMC) requirements to EN 61326. The

mechanical fastening of the pressure

sensor does not require any additional

strain relief, as the construction of the

cable is suitable to take a maximum

tensile force of 1000 N. The cable’s

individual signal wires are epoxy sealed

into the casing to protect against

water ingress. This probe is ideal for

monitoring drainage, bore depth and

river height. It can also be used to

measure water with dissolved solids

and other liquids.

Oxygen diffuses through the membrane

onto the cathode, where it reacts

chemically and then combines with the

anode. This chemical process develops

an electric current, which flows through

a built-in resistor. The resistor converts

the current (microamps) into millivolts.

This millivolt signal is led to the Data

Logger via a two core cable.

The probe is virtually maintenance

free, requiring only that its membrane

be kept reasonably clean. The anode

remains fully active through its lifetime

of several years. The membrane is very

robust and can be wiped clean with a

cloth or paper. It is recommended that

the membrane be cleaned from time to

time to ensure maximum reliability.

Starloggers

Standard Starlogger Model 6004D-11

Designed for trouble-free operation

in a wide range of applications, the

Starlogger is a high performance,

upward-compatible replacement for

the original STARLOG Portable Data

Logger (PDL). The Starlogger is easy to

program and offers wide signal capacity

and range.

All Starloggers feature eight (10-bit)

analog channels, four (16-bit) counter/

frequency channels, and 2 (16-bit)

HSIO lines with 8 channels each. Their

memory capacity is 512K CMOS RAM,

enough storage for many months of

recording. They also provide two power

sources for external instruments. The

range of scan rates extends from 125

milliseconds to 5 minutes.

The Starlogger uses standard

asynchronous RS-232 serial

communications to communicate with

an IBM PC or compatible computer

or a modem connected to a telemetry

system.

Starloggers are completely portable.

They contain an internal battery supply

for one year of normal operation.

Starloggers are fully programmable

using the STARLOG programming

language.

Prologger

The Prologger 7001D-11 sets new

standards in accuracy and input

range. It is packaged in the robust

enclosure so familiar to Starlog users

with twice the accuracy, eight times

the resolution, and sixteen times the

dynamic range. It is the ideal upgrade

from its predecessor the 7000 Macro

Logger. All Prologger analogue and

digital inputs are processed with 16

bit resolution. The sixteen inputs now

support the following ranges:

±5.000V (155uV/bit resolution)

±500mV (15.5uV/bit resolution)

±50mV (1.55uV/bit resolution)

±5mV (155nV/bit resolution)

The superior accuracy of the new

design means that input voltages will

be converted to better than 0.05%

of full scale over the full operating

temperature range, and 0.1% in the

5mV range.

The Prologger’s increased memory

capacity means you can acquire more

data or increase the period between

downloads. The unit also includes all

the familiar Starlog features such as

SDI-12 instrument support, modem

command/dial-out support, universal

battery pack, continuous power source,

scheme control of power supplies, and

field upgradable control firmware.

Datalogger Field Termination Strips

STARLOGGER Field Termination Strip and Mounting Frame Model 6103E

STARLOG Field Termination Strips

A Field Termination Strip (FTS) is normally added to a Data Logger to simplify instrument connection and to identify one logging site from another.

The FTS extends a Data Logger’s

signal connections to a row of

numbered screw terminals. These

terminals, mounted on a printed

circuit board, make it easy to

connect/disconnect instruments

to/from the Logger on site. An

FTS is a welcome option when

logging projects use more than one

instrument.

The FTS provides mounting

facilities for reference resistors

and additional signal filtering

and conditioning components.

It also has an optional facility to

differentiate one logging site from

another, called Site Identification

(Site ID).

To record different types of input

signals, signal attenuation and

amplification options are available

for the STARLOG Data Logger.

Our selection includes Signal

Amplifiers, Special Interfaces,

Voltage Dividers, Current Loop

References, other Special Purpose

Modules and Precision Reference

Resistors.

Signal conditioning equipment

is typically soldered onto a Field

Termination Strip becoming part of

the on-site installation.

The FTS is available with a steel frame

(Model 6103E) which is designed to fit

within the Model 6701 Weatherproof

Enclosure.

The FTS mounts onto the steel frame

with hinged clips, allowing it to be

swung clear of the frame for on-site

installation and wiring maintenance.

The Starlogger Field Termination Strip

is compatible with the previous PDL

Field Termination Strip (6103B) except

that Site ID is offered as a separate

module and counter channels have

different allocations.

Systems, Integration Enclosures & Radiation Screens

Unidata Systems Integration

Unidata can provide equipment

components for a range of

applications along with engineering

support services, data logging

scheme writing and Neon and Starlog

applications software.

Unidata can also provide systems

integration services to build up

specific systems, combining Unidata

equipment, and purpose built

enclosures, and Systems Integration,

documentation, and Systems

installation services for major projects.

When systems are developed, the

customer’s specific requirements

are considered and the configuration

is decided based on technical and

commercial criteria. One key issue

is maintainability and field support,

especially for remote systems. The

Neon Applications Software allows for

remote configuration and adjustment

of logger / Neon Remote Terminal

configuration, which can be very cost

effective, minimizing or eliminating

the need to travel to remote logging

sites to reconfigure and diagnose the

equipment.

Systems can be set up inside

customer defined enclosures, with the

only connection necessary being a

field termination strip or panel, which

simplifies the field installation process.

When Systems are considered, there

are some key issues to consider:

• Instrumentselection,deciding

on the most appropriate

measurement method.

• Sitepowerselection,decidingif

a sealed lead acid battery with

solar panel support is best, or

an alternative power source, for

example a bank of high capacity

lithium batteries may be best.

Unidata has battery calculator

tools available to decide on

the best battery option for such

systems.

• Instrumentenclosureselection,

deciding on the most appropriate

housing, weatherproof

polycarbonate or steel enclosure,

with or without sun shade

protection.

• Telemetryselection,eitherdialup,

or IP communications via cell phone

or satellite communications.

• Loggingandreportinginterval

selection, deciding on the balance

between the cost of the telemetry.

communications ( important for

satellite links) and the need for 5

minute, 15 minute, hourly or daily

reporting.

• Powerusageconsiderations,

deciding on the balance between

battery consumption and the logging

and reporting interval.

Please contact Unidata for more

information on Systems Integration.

Some Examples of Systems are shown

below.

The Weatherproof Enclosure protects

the Data Logger from moisture, wind

and sun, and would-be vandals. It

is constructed of robust, glass-filled

polycarbonate which has been UV

stabilized for outdoor use. Signal cables

enter through glands in the base of the

enclosure. The logger is installed and

removed from the enclosure through the

front lid which seals the enclosure when

shut. Tamperproof screws and a key are

supplied.

Model 6701M includes pole mounting

hardware and fittings which provide

a complete field installation set. The

Model 6701D is a double width version

of this enclosure.

Communicating with Data Loggers

Cables, Connectors and Interfaces

The model 6543A Protocol Converter

converts Modbus to SDI-12 requests

OR converts HSIO data to Modbus

data. This allows Unidata data loggers

and third party SDI-12 sensors to be

integrated into process control (PLC,

SCADA) systems. Modbus data is in

RTU format. Modbus communications

are via RS232 or RS485.


Model Type

6543A Protocol Converter

Modbus to SDI-12 Conversion:

The model 6543A Protocol Converter

acts as a Modbus slave on a Modbus

RTU bus. On receipt of certain Modbus

commands the Protocol Converter

module initiates SDI-12 commands,

awaits the response and returns the

results as Modbus values. The data

returned is selectable as either a binary

decimal values with a sign delimiter or

an IEEE 32bit floating point values.

Modbus to HSIO Conversion:

The 6543A Protocol Converter can

also act as a HSIO slave on the HSIO

connection from a UNIDATA data

logger or Starflow. On receipt of HSIO

data the Protocol Converter module

stores the HSIO data into memory. On

receipt of certain Modbus commands,

the Protocol Converter returns the

requested memory values as Modbus

values. The data returned is an exact

representation of the HSIO value/s

received.

SDI-12 Dual Listener Model 6411A


Model Description

6411A SDI 12 Dual Listener Interface

This device assists with integration

projects where you may wish to have

both a Starlogger and a neon remote

Terminal use the same SDI-12 bus.

Normally two SDI-12 masters on the

same bus will cause problems, but with

this device a master logger can control

all SDI-12 communications activity,

but if that logger fails, the secondary

logger for example, a Neon remote

Terminal, can assume command of the

SDI bus and can allow the operation of

the system to continue in the event of

failure.
