2. BD Series Introduction

RFI's UHF Bi-Directional Amplifier (BDA) is a compact IP-rated wall or pole mountable, RF-

transparent repeater. The BDA is ideal for rebroadcasting RF coverage in confined areas

such as in tunnels and mining sites as well as remote locations. Depending on the model, it

can either pass a 5MHz or 1.5MHz window in each direction in the selected frequency sub

band. The BDA’s RF-transparent operation is compatible with most analogue and digital

technologies. Communications content is passed without demodulation and network

protocol features, such as encryption and over-the-air-rekeying which are passed securely.

The standard architecture of this BDA provides user-friendly, convenient and efficient in-

field maintenance. The BDA is available in standard and high-power variants with optional

RF over Fibre interface and multiple power supply and battery backup options.

Figure 1 – BD Series BD

Frequency sub bands: BD series is available in six different UHF sub bands:

Model Number Frequency Sub Band

BD3840-yyyy-zz 380-400MHz








RF Power Capabilities: These BDAs come in standard and high-power variants. The high-power models feature a High-Power Amplifier (HPA) in either Downlink path, Uplink path or both:

BDxxxx-1yyy-zz High Power Downlink, Standard Power Uplink

BDxxxx-2yyy-zz Standard Power Downlink, High Power Uplink

BDxxxx-3yyy-zz High Power Downlink and Uplink

The maximum RF output power and gain range for the standard and high-power models are:

Maximum RF Output Power dBm

High Power +40 (1 Carrier), +37 (2 Carriers), +34 (4 Carriers), +31 (8 Carriers)

Standard +21 (1 Carrier), +18 (2 Carriers), +15 (4 Carriers), +12 (8 Carriers)

Gain Range dB High Power 53-84*

Standard 38-69

External filtering is required for >70dB gains to provide the required isolation for the BDA.

RF over Fibre (RFoF): BD series BDAs are also available with the optional RF over Fibre interface. When RFoF is used, normally two BDAs are required. One BDA will be the headend unit and will be installed near the donor RF site. The other BDA is the remote unit which provides coverage in the desired coverage area and communicates with the headend over Fibre. There are two options available for the Fibre interface: Dual fibre (separate Tx and Rx) and Single Fibre (WDM):

Power Supply Options:

BD series BDAs are available in 240V AC as well as 12V, 24V and 48V DC models:

3. Physical Dimensions

The physical dimensions of the BD series BDA are illustrated in the below figure

Figure 2 – Physical Dimensions



4. BD Series Components

4.1 BDASC Module

Figure 3 – BDASC Module

BDASC is a high-linearity, single or multi carrier Bi-Directional RF amplifier.

The gain of the BDA is configurable for both the uplink (UL) and downlink (DL) RF signal path directions via the BDASC module. This gain value is configurable in 1dB steps via the front panel rotary switches:

Figure 4 – BDASC Module’s Gain Setting Rotary Switches

The gain value is also configurable via the command line interface (CLI).

Depending on the gain settings, Automatic Gain Control (AGC) operation may be enabled to provide up to 31dB of gain control.

BDASC features excellent Noise Figure (NF) and output amplifier 3rd Order Output Intercept Point (3OIP) specifications.

BDASC module has three (3) front panel LED indicators to provide a visible indication of the module’s DC Power (green), Alarm (red) and AGC (yellow) status, with corresponding information also available via the CLI.



4.2 HPA Module

High Power Amplifiers (HPA) module is a non-adjustable fixed gain amplifier used to boost the output power from the BDASC in high power variants of the BD series BDAs.

Depending on the model, the BDA may have only one HPA in either Downlink or Uplink paths or two BDAs for both Downlink and Uplink.

Figure 5 – HPA Module

4.3 Duplexer

BD Series BDAs feature a band pass / band reject, compact milled UHF duplexer. Depending on the model, the duplexer covers one of these sub bands:

380-400MHz, 400-430MHz, 430-450MHz, 450-470MHz, 470-500MHz, 500-520MHz

The duplexer combines/separates the transmit and receive signals at the donor and rebroadcast sides and provides the necessary isolation between the two signals.

The non-RFoF variants of the BDA feature two duplexers in one enclosure (for donor and rebroadcast sides) whereas the RFoF models have one duplexer in each enclosure (headend or remote).

4.4 RF over Fibre (RFoF) Modules

Depending on the model, the RFoF variants of the BD series BDAs feature either a single (WDM) or dual (Simplex with separate Tx and Rx) RFoF modules. The optical connectors are of FC/APC type and are located inside the BDA’s housing.



4.5 Base Plate

The base plate is located at the bottom of the BDA with all the connectors to the

external equipment including the service and donor antenna connectors (depending on the model), power input, Ethernet Comms Port and Fibre Input/output ports (depending on the model).

The connector positions in the RFoF, AC Power models is shown in the below picture:

M10 Washer(s).

Figure 13 - M10 “Rawlplug - through bolt” (R-XPTIIA4-10065/5) OR equivalent –

recommended for wall mounting.

6.2.2 Wall Mounting

✓ Choose the wall location and prepare the required elements

✓ Mark the drill holes and position of the BDA on the wall

✓ Drill the holes, insert the bolts and mount the wall brackets

✓ Lift the BDA onto the wall mounting brackets



✓ Wall compatibility

The BD Series BDA, including wall mount bracket assembly, should be fixed to a

solid wall (such as brick, block work, or concrete). Due to the weight of the BDA,

it is NOT recommended to fix to a hollow/cavity wall.

✓ Plan for the mounting

Check the actual fixing centres, figure below, and overall dimensions of the BDA

enclosure. The BDA is supplied with two wall mounting brackets; when the BDA

is mounted on these brackets adequate ventilation is provided between the BDA

and the wall to which it is fixed.

Figure 14 - Wall mount fixing dimensions & centres and BDA front elevation view.

✓ Fix bolts

Fix M10 “Rawlplug - through bolts” (50 to 75 mm in length) or similar into the

wall at the dimensions as illustrated above using equipment as specified by

the fixing manufacturer. A recommended method is set out below. Care must



be taken to ensure the alignment of the four fixings. A spirit level or plumb line

should be used to ensure horizontal/vertical alignment.

✓ Plan for connection cable clearances

The RF, power & optical (where fitted) connections are located on the

bottom/feet end of the BDA and will need at least 300 mm of vertical clearance

below the BDA to enable the connections to be made. The minimum bend

radius for RF and optical (where fitted) cables must not be less than the

recommendations made by the cable manufacturer. Plan the cable runs and

ensure adequate space is available.

✓ Allow for front door opening

Ensure there is enough space at the front of the BDA to allow the front door to

be fully opened and for maintenance personnel to obtain access to the BDA

with interface or test equipment. Allow an additional 500 mm of space in front

of the BDA when the door is fully open.

Figure 15 - BD Series BDA wall mount side elevation view.



6.2.3 Wall mount Procedure

✓ Mark out on the chosen wall the fixing centres of the repeater. Use the packing box

accessory insert, unfolded, which has drill hole positions punched in the

cardboard to suit the mounting bracket holes

Figure 16 - Wall mount bracket, bolt drilling hole alignment template - accessories insert.

✓ Drill the wall with the correct size masonry bit as specified by the fixing manufacturer.

Note: It is good practice to wear goggles and gloves to protect your eyes and

hands, from flying debris, and ear plugs when using power tools.

✓ Hold the drill bit against the mark and begin drilling slowly so that the bit does

not wander from the wanted position. The wall should be drilled to a depth

which is enough to accommodate the full length of the fixing.

✓ Clear the hole of drilling dust using a blow pump.

✓ Insert the fixings so that the top of the sleeve/anchor section is level with the wall surface.

✓ Gently tighten the bolt by hand so that the anchor section of the fixing

expands and grips the inside of the hole.

✓ As the bolt pulls its way in, the sides of the anchor section are forced

outwards, gripping the internal side of the hole.

✓ Once all four fixings are in place, carefully remove the four bolts.

✓ Align the 2 off mounting brackets with the with the four fixing bolts.



✓ Carefully place the mounting brackets over the fixing bolts to the wall, fit the fixing nuts and tighten them.

✓ Lift and carefully place the BDA, with factory fitted M8 shoulder bolts, onto and

in the M8 open slots of the top bracket. This is best done with 2 persons lifting

the BDA and with the BDA slightly angled away from the wall at its base end.

✓ Great care should be exercised here as the BDA is heavy.

✓ Once the BDA is located on the top bracket align all of the other M8 fixing

holes on the BDA with the mounting bracket fixing holes and fit the M8

securing bolts, including spring washers, through the mounting bracket holes

into the BDA and screw until tightened.

6.2.4 POLE MOUNTING

✓ Bracket Assembly

For pole mounting use 2 off UC1 pole mounting kits, covering pole diameters

from 20 to 75 mm, and 2 off wall mounting brackets. One set of UC1 and that

assembly is assembled to the pole. Figure below illustrates pole brackets

assembled for a pole mount installation.

Figure 17 - Pole mount bracket Assembly (Top brackets)



Step1: Figure 18- Plan view, Pole mount assembly

Step 2: Figure 19- Plan view, Pole mount assembly

6.3 RF Level Configuration

The RF output of the BD Series BDA is adjusted on the BDASC module. This is specified as a composite RF power rating. For example, in the standard models, the BDASC can provide a maximum +22dBm for a single carrier, or 12dBm per carrier (total of 15dBm) for six (6) carriers. This duplexer and cable losses should be added to this calculate the RF power out of the BDA. In high power models, the High-Power Amplifier (HPA) is fitted in either or both downlink and uplink RF paths. The HPA’s have a fixed gain of 35dB (+/- 2dB). A fixed 20 dB attenuator is fitted between the BDASC and the HPA to firstly limit the input power into the HPA into a safe operating region



and secondly reduce the overall path gain in accordance to the predetermined link budget.

6.4 Setting Gain (BDASC)

The available configurable gain in each RF path of the BDASC is between 39 and 70dB in 1dB increments, independently adjustable using the wheel switches on the front face of the BDASC.

Figure 20- Gain Setting Switches on BDASC

6.5 AGC Operation

The BDASC has Automatic Gain Control (AGC) capability that is enabled in either (or both) downlink and uplink RF paths via the Command Line Interface (CLI) and operates as follows;

The full available AGC range is 31dB, however this is dependent on the gain (attenuator) setting. Full AGC is available when the gain in the selected path is set to 70dB (no attenuation) A nominated “Target Value” in dBm for the path’s RF output level is nominated via the Command Line Interface (CLI). When this output level is reached, the BDASC will utilise the remaining attenuator range to prevent that RF output level from increasing further if the input signal level increases. For example, where 60dB gain is set for a path, 10dB of the available 31dB attenuator range has been utilized. The remaining 21dB is available for AGC use. If the input signal rises by more than that 21dB of remaining AGC controlling range, the BDASC output will then increase in step with further RF input signal level rise, until the BDASC maximum RF output level is reached.

This AGC process may be represented by the following diagram;

WARNING: When HPAs are used, care should be taken to ensure they are not overdriven by the available BDASC RF output levels. Optional attenuators may be required to be inserted between the BDASC RF output(s) and the HPA input(s) to maintain HPA RF output levels at desired per- carrier output values, and at all times below overload levels.

6.6 Other BDASC and HPA settings

Factory Reset Function A “reset” switch is available on BDASC to facilitate recovery if the IP address is changed and then forgotten Ethernet Connectivity A Command Line Interface (CLI), that is accessible via the Ethernet connection on BDASC using a terminal emulation program (such as Teraterm™ or similar), provides access to status, alarm and configuration parameters from the module. This is accessible through the RJ45 Ethernet port at the bottom of the BDA. Alarms Output Dry relay “Form C” contacts are available on BDASC and HPA to provide alarm notification for connection to external equipment if required.

WARNING: Neither UL nor DL paths of the BDASC should be driven above its maximum RF Input Power level which is 0dBm. Any level above this may result in permanent damage. If AGC mode is not enabled, care should be particularly given to preventing overdriving the RF input.



7. BDA Configuration

7.1 Command Line Interface (CLI) and Software (S/W) Flash Upgrading

Only the BDASC module has a CLI interface, the HPA current parameters however are monitored via the BDASC if used as an option. There is no direct CLI interface to the HPA module.

When the BD series BDA is powered on, check that the green “Power” LED light on the front panel of the BDASC is illuminated. Any other illuminated LEDs will be reflecting the current state of the AGC and Alarms, based on the current programmed configuration and operating status.

Using the Command Line Interface (CLI), configure the unit as required.

7.2 Ethernet Connection Set-up

The BDASC utilises an on-board communications protocol to provide user-configurability for the module. This CLI can be accessed locally by connecting to the BDA via an Ethernet cable from a computer/tablet and using a terminal emulation program (such as HyperTerminal™, TeraTerm™, or similar). Access can also be provided remotely via a TCP/IP (or Internet) network.

When accessing the BDASC, TCP/IP ports 23 (for the CLI), and 69 (for firmware flash upgrading) must be “open” for use.

7.3 Command Line Interface (CLI) Operation

IP Address Initiate your terminal emulation program (using TeraTerm™ as an example), and type in the TCP/IP address and port fields as follows;



Click “OK”. Connectivity to the BDASC is successful when the following “Log In” prompt appears.

Should the terminal emulation program be unable to open this session, it may be necessary to set the IP address of your computer to an address in the same IP range (i.e. 192.168.1.180). Using Windows XP™ as an example this is done in the following manner;

1. Select “Start” from status menu

2. Single click – “Control Panel”

3. Double click – “Network Connections”

4. Double click - “Local Area Connection”

5. In Local Area Connections Status box, single click the “Properties” button.

6. When the Local Area Connection Properties box opens, select only the “Internet

Protocol (TCP/IP)” choice.

7. Click “Properties” button.

8. Click “Use the following IP address.

9. Enter next to IP address 192.168.1.180

10. Enter next to Subnet mask 255.255.255.0

11. Enter next to Default gateway 192.168.1.1

12. Click “OK” to initiate changes.

Using Windows 7™ as an example this is done in the following manner;

1. Select “Start” from status menu

2. Single click – “Control Panel”

3. Single click – “Network and Sharing Center”

4. Single click - “Change Adapter Settings” on the left hand side menu

5. Single Click – “Local Area Connection” box

6. Single Click – “Change Settings of this Connection”

7. When the Local Area Connection Properties

box opens, select only the “Internet Protocol 4

(TCP/IPv4)” choice.

8. Click “Properties” button.

9. Click “Use the following IP address”.

10. Enter next to IP address 192.168.1.180

11. Enter next to Subnet mask 255.255.255.0

12. Enter next to Default gateway 192.168.1.1

13. Click “OK” to initiate changes.

Should you still be unable to successfully connect to the BDASC via the default IP



address then the IP address may have already been changed. If there is no possibility of recovering the changed IP address, then it will be necessary to reset the BDASC to the factory default settings.

7.4 Reset Factory Default Ethernet Addresses and Access.

To reset the BDASC back to the Factory Default settings will mean a complete reset of configuration settings. To do this, simply press the BDASC Factory Reset button (located next to the LED indicators on the front panel) for more than three (3) seconds. Wait for the BDASC to complete its default re-configuration and to restart.

Example: 36.36[C]

Note: As a factory default, the AGC status in both the Downlink and Uplink paths is set to “on” and the respective Target RF Output Powers are both set to “15dBm”. When changing

AGC status, please be aware of the RF signal level input and ensure you limit this to

within the safe operating region or increase the attenuation by reducing the gain to reduce

the risk of possible damage. This is particularly important when driving into HPA’s.

To change the gain via the rotary switches, disable the AGC on the respective path.

Downlink Gain: The configured Downlink gain value

Example: “Downlink Gain = 70[dBm]”

When Downlink AGC is off, the rotary gain switches set the desired gain (in dB). Valid settings are in the range 40-70dB. Settings less than 40 will set the gain at 40, and settings above 70 will set the gain at 70.

If Downlink AGC is on, then the rotary switches cannot be adjusted, and the gain value will be fixed at the rotary switches setting when the Downlink AGC was set to on. To change the gain setting when Downlink AGC is on, it must be first turned off, the rotary switches set to the new gain value, and then Downlink AGC turned back on.

Uplink Gain: The configured Uplink gain value

Example: “Uplink Gain 70[dBm]”

When Uplink AGC is off, the rotary gain switches set the desired gain (in dB). Valid settings are in the range 40-70dB. Settings less than 40 will set the gain at 40, and settings above 70 will set the gain at 70.

If Uplink AGC is on, then the rotary switches cannot be adjusted, and the gain value will be fixed at the rotary switches setting when the Uplink AGC was set to on. To change the gain setting when Uplink AGC is on, it must be first turned off, the rotary switches set to the new gain value, and then Uplink AGC turned back on.

Downlink AGC Status: The current Downlink AGC status

Example: “ON”

The Downlink AGC Status command is an on/off command, and when used to turn AGC on it must also contain the target



RF output level. To change this, enter;

BDA>dl agc

on 15 and

press “enter” or

BDA>dl agc off and press “enter”

Note: Valid Downlink Target RF Output Power values are within 08 to 22dBm

Downlink Target Value: The configured Downlink Target RF Output Power

Example: “15[dBm]”

Uplink AGC Status: The current Uplink AGC status

Example: “ON”

The Uplink AGC Status command is an on/off command, and when used to turn AGC on it must also contain the target RF output level.


BDA>ul agc

on 15 and

press “enter” or

BDA>ul agc off and press “enter”

Note: Valid Uplink Target RF Output Power values are within 08 to 22dBm

Uplink Target Value: The configured Uplink Target RF Output Power

Example: “15[dBm]”

Downlink Current: The current BDASC and HPA Downlink current consumption

Example: “BDA 0.58[A], HPA NONE”

To enable monitoring of (optional) HPA

current measurement enter; BDA>dl

hpa use and press “enter”

HPA DL Current outside the range 1A (lower limit) and 5A

(upper limit) will create an alarm to disable monitoring of

(optional) HPA current measurement enter;



BDA>dl hpa not use and press “enter”

Downlink Alarm Status: The current BDASC and HPA Downlink Alarm Status

Example: “BDA NORMAL, HPA NONE”

Uplink Current: The current BDASC and HPA Uplink current consumption

Example:

“BDA 0.58[A], HPA NONE”

To enable monitoring of (optional) HPA current measurement enter;

BDA>ul hpa use and press “enter”

HPA UL Current outside the range 1A and 5A will create an alarm

To disable monitoring of (optional) HPA

current measurement enter; BDA>ul hpa

not use and press “enter”

Uplink Alarm Status: The current BDASC and HPA Uplink Alarm Status

Example: “BDA NORMAL, HPA NONE”

Voltage: The current BDASC internal voltage regulator output

Example: “8.32[V]”

Voltage Alarm Status: The current BDASC internal voltage regulator Alarm Status

Example: “NORMAL”

Note: The factory default HPA current consumption alarm thresholds are 450Ma (min.) and 950mA (max.) respectively. The same threshold values are set for both the downlink and downlink paths. For alternate HPAs, these threshold values may be adjusted using the following commands;

BDA>dul hpa current l 0500 and press “enter”

This will set the lower HPA current consumption alarm

threshold to 500mA BDA>dul hpa current u 1200 and



press “enter”

This will set the upper HPA current consumption alarm threshold to 1200mA

8. Maintenance, Inspection and Repair Advice

No special maintenance program is required for the BDA. The units’ installation should be checked for visible signs of damage, duress (overheating/burning marks, loose cabling, etc) or rodent infestation or attack. Any such signs should be addressed through repair or other remedial actions.

8.1 Firmware Upgrades

Firmware upgrades may periodically be made available and may be uploaded into the BDASC using an FTP program if desired. RFI recommends the TFTPD32 FTP software for use in the upgrade process, and it is available here: http://tftpd32.jounin.net.

TFTPD32 should be configured for use with the BDASC as follows;

✓ Ensure your PC’s is configured to a TCPIP address in the same range as the

current BDASC TCPIP address (the “Server Interface” shown below)

✓ Enter the BDASC’s current TCPIP address (the “Host”)

✓ Set the “Port” to “69”, and ensure this port is open for comms in your PC (and

firewall) settings

✓ Select the firmware file to be uploaded.

Note that the filename extension should be in lower case – i.e. “.bin”. (the “Local File”)

✓ Click “PUT” to start the firmware file transfer process (this should take ~3 seconds to

complete)

WARNING: Do not remove or interrupt DC power or TCPIP communications

during the following process or an unrecoverable state may result in the

BDASC which may render it inoperable.

http://tftpd32.jounin.net/



Note: After approximately 30 seconds from completion of the firmware file

upload, the BDASC will re-boot and will be upgraded successfully and available

for use.

8.2 BDASC Fault Diagnostics

The Green LED indicates that the DC power is connected and on. The Yellow LED indicates that either or both the UL and DL paths have AGC enabled. The RED LED will illuminate if the BDASC is in the alarm state. When in alarm state, connect to BDASC via the Ethernet port and read the status screen Reading the DOWNLINK, UPLINK and or VOLTAGE Alarm STATUS conditions will indicate where the fault is reported.
