Signal Pinout Descriptions

The interface signals are available through the 11-pin header. All pins operate on VCC CMOS

levels. The following 5 signals are commonly used in MaxStream module applications:

• DI (pin 4 – Data In)

• DO (pin 3 – Data Out)

• VCC (pin 10 – Power)

• GND (pin 11 – Ground)

• (pin 1 – Clear-to-Send)

The remaining 6 pins (SLEEP (PWRDN), , , RX LED, /PWR, ) are available for

additional functionality. Go to the “XStream Advanced Programming & Configuration Manual” for

more detailed information about the module signal pinouts.

Application Circuit

Figure 2. Application Circuit – connection to host processor

Serial Data

Data enters the XStream Module through the DI Pin as an asynchronous serial signal. The signal

should idle high when no data is being transmitted.

Each data packet consists of a start bit (low), 8 data bits (least significant bit first) and a stop bit

(high). The following figure illustrates the serial bit pattern of data passing through the module.

Figure 3. UART data packet 0x1F (decimal number “31”) as transmitted through the XStream Module

The XStream Modules transfer 8 bits over-the-air. The start and stop bits from the UART signal

are not transmitted, but are regenerated in the receiving module.

DI (Data In) Buffer

Once serial data has entered the XStream Module through the Data In (DI) Pin, the data is stored

in the DI Buffer until it can be transmitted.

Once the first byte of data enters the DI Buffer, the module begins to initialize the RF channel

(unless RF data is being received). In the case where the module is receiving RF data, the serial

data is stored in the DI Buffer. When the DI Buffer has only 17 bytes of memory left, the

XStream Module de-asserts (high) to signal to the host device to stop sending data. re-

asserts once the DI Buffer has at least 35 bytes available in memory. Once in the DI Buffer, the

data is packetized for transmission. [The packet structure is broken down on the next page.]

<VID> Factory assigned Vendor ID number

RF Components Serial Communications

The XStream Wireless OEM Module interfaces to a host device through a CMOS-level

asynchronous serial port. Through its serial port, the XStream Module can communicate directly

with any UART-interfaced or RS-232/485/422 device. [Timing specifications illustrated on page 4]

UART-Interfaced Data Flow

Devices that have a UART interface can connect directly through the pins of the XStream Wireless

OEM Module as is shown in the figure below.

RS-232 and RS-485/422 Data Flow

Wiring the XStream Module to a host device serial port enables the host device to communicate

wirelessly. To transmit, the host device simply sends serial data to the XStream Module pins. The

XStream Module then converts the data to Frequency Hopping Spread Spectrum (FHSS) FCC-

approved wireless data. Once transmitted, the over-the-air data can be detected by receiving

XStream Modules, checked for data integrity and then sent to a receiving device.

facilitate the connection between XStream Wireless OEM Modules and serial devices. Many

integrators develop their own interfacing circuitry; others use MaxStream’s XIB-R Interface

Board. In either case, the following sections illustrate how to interface with XStream Wireless

OEM Modules by illustrating properties of the MaxStream XIB-R Interface Board.

See the “XStream Advanced Programming and Configuration” Manual for more detailed

information about each individual component of the XStream Development Kit.

MaxStream Interface Board (Part Number: XIB-R)

The MaxStream Interface board was developed to provide means of connecting the XStream

Module to any system having an RS-232 or RS-485/422 connection. Since the XStream Module

requires signals to enter at CMOS voltages, one of the main functions of the interface board is to

convert signals between CMOS levels (5 VDC regulated) and RS-232 levels (-12 to +12V). The

MaxStream Interface Board includes the following built-in features:

• DIP Switch (facilitates the choosing between modes of operation)

• Configuration Switch

• Power Switch

• LEDs

• DB-9 Connector

• Power Connector



MaxStream Interface Board Components

9a. Power Switch

Move the Power Switch to the on (up) position to power the Interface Board. DIP Switch [10a] settings are only read during a power-up sequence.

9b. LEDs

The LED indicators visualize diagnostic status information. The module’s status is represented as follows: Yellow (top LED) = Serial Data Out Green (middle) = Serial Data In Red (bottom) = Power/TX Indicator (Red light is on when powered, off briefly during RF transmission)

9c. DB—9 Connector

Standard female DB-9 (RS-232) DCE connector (This connector can be also used for RS-485 and RS-422 connections.)

9d. Power Connector

7-18 VDC Power Connector (Center positive, 5.5/2.1mm) – Power can also be supplied through Pin 9 of the DB-9 Connector.

10a. DIP Switch

The DIP Switch configures the XStream OEM Module to operate in different modes. DIP Switch settings are only read and applied during a powering-on sequence. During power-up, AT Commands are sent to the module according to positions set on the DIP Switch.

[See Figure 11 below for DIP Switch settings]

10b. Configuration Switch

The Configuration Switch provides an alternate way to enter “AT Command Mode”. To enter “AT Command Mode” at the radio modem’s default baud rate, hold the Configuration Switch down while powering on the module using the Power Switch [9a].

Figure 11. MaxStream Interface Board DIP Switch Settings

* The “Restore Defaults” setting, for switches 1 & 2, can be used to restore all XStream Module Parameters to their default states. Once switches are in their “On” (up) positions, reset occurs during next power- up.



Module Configuration AT Commands listed in this section represent user-accessible parameters available to XStream

Modules as of firmware version 4.29. [Firmware version can be verified using VR (Firmware

Version) Command.]

AT Command Mode

AT Command Mode is one of the five modes of operation used by

XStream Modules (The other four modes are Idle, Transmit, Receive &

Sleep). AT Command Mode provides a state in which XStream Module

Parameters can be configured to fit specific design criteria.

For More Information

Go to the 'Modes of Operation'chapter of the "XStream

Advanced Programming & Configuration" Manual for

more information.

The advanced manual is available on the MaxStream CD

or on the web: www.MaxStream.net

To enter AT Command Mode, use any of the following methods:

1. When using AT Commands:

a. When using XStream-CTU Software, the “Program Module”, “Restore Module Defaults” and “Get Parameters …” buttons automatically trigger entrance into AT Command Mode.

b. When using serial communications software or a microcontroller, send the 3-character command sequence “+++”. [Command character ‘+’ can be changed to another ASCII value using CC (Command Sequence Character) Command]

2. When using Binary Commands: Assert (high) the /CMD pin.

3. Assert (low) the pin* and turn the power switch off and back on. (If using the MaxStream Interface Board, the same result can be achieved by keeping the configuration button pressed while turning off and then on again the power switch.)

Important: * Do not tie the pin to the microprocessor.

Once in AT Command Mode, parameters can be adjusted using either AT or Binary Commands.

For parameters to persist in the module’s memory the next time the module is powered, changes

must be saved to non-volatile memory using WR (Write) Command. Otherwise, the parameter

values are reset to their previously stored value the next time the module is powered-on.

To exit AT Command Mode

1. If no valid AT Commands are received within the time specified by CT (Time Out)

Command, the module automatically returns to Idle Mode.

2. AT Command Mode can be exited explicitly by issuing CN (Exit AT Command Mode) Command.



Configuration Software

XStream-CTU (XCTU) Software

XStream-CTU is MaxStream-provided software used to interface with and configure XStream

Modules. The software application is organized into 3 tabs:

• Setup tab - Setup PC serial ports to interface with XStream Module assemblies (A module assembly is the combination of an XStream Module and an interfacing board such as MaxStream part number XIB-R. The XStream-PKG-R Stand-Alone Radio Modem already encases a module assembly.)

• Configuration tab – Configure parameters of XStream modules using AT Commands

• Com Test tab – Test range of XStream Modules and monitor packets sent and received

Figure 12. XStream-CTU User Interface (Setup, Configuration & Com Test tabs)

Installing XStream-CTU Software Figure 13. Module Assembly

Double-click the “xstreamCTU.exe” file and follow the prompts of

the installation screens. The “xstreamCTU.exe” file is located in

the MaxStream CD “Software” folder and also on the web:

http://www.maxstream.net/products_xstreamctu.html

Using XStream-CTU Software

In order to use the XStream-CTU software, a module assembly

[Figure 13] must be connected to the serial port of a PC.

The baud rate of the serial port (“Setup” tab) must match the

baud rate of the module (BD (Baud Rate) Command on the

“Configuration” tab).

Serial Communications Software

Serial Communications Software can also be used to issue AT Commands.

“HyperTerminal” (Windows XP Start Menu: All Programs Accessories Communications

HyperTerminal) can be used and comes installed with Microsoft Windows XP, 2000 and NT. “Pro

Comm” is another commonly-used Serial Communications Software solution.

AT Commands must be issued as follows:

AT + [2 Character ASCII Command] + [Optional Space] + [Parameter (HEX)] + [CR]

(CR = Carriage return)
