QUICK START GUIDE

The steps below contain the essential information needed to place the OEM trans­ceiver in service. Because the transceiver is designed for use in other pieces of
equipment, these steps assume that prior testing and evaluation have been
conducted with the host device. If not, please refer to Section 3.0, Benchtop Setup
and Evaluation for proper interface wiring and configuration.

1. Mount the transceiver module using the four holes provided.

• If possible, select a mounting location that allo ws vie wing the status LEDs and
provides ready access to the antenna connector.

• Use standoff hardware to secure the board to the host device.

• When mounting the board, use care to align the transceiver’s 16-pin header
connector with the mating pins in the host device.

2. Connect the antenna system to the transceiver

• Use only with antenna/feedline assemblies that have been expressly tested
and approved for such service by Microwave Data Systems Inc.

• Use an MMCX-type male connector to attach the antenna to the transceiver.

• For best performance, antennas should be mounted in the clear, with an
unobstructed path in the direction of desired transmission/reception.

3. Apply power and observe the LEDs for proper operation. The LED
command must be set to ON (LEDS ON).

After 16 seconds...

• The GP lamp should be lit continuously

• The DCD lamp should be lit continuously—if synchronization with another unit
has been achieved

• The Remote radio(s) should be transmitting data (TXD) and receiving data
(RXD) with its associated station

1.0 ABOUT THIS MANUAL

This manual is intended to guide technical personnel in the integration of
MDS TransNET OEM™ transceivers into existing electronic equipment. The
OEM transceiver is designed for use inside Remote Terminal Units (RTUs),
Programmable Logic Controllers (PLCs) and other equipment associated
with remote data collection, telemetry and control.

The manual provides instructions for interface connections, hardware
mounting, and programming commands. Following integration of the
transceiver, it is recommended that a copy of this manual be retained for
future reference by technical personnel.

2.0 PRODUCT DESCRIPTION

The OEM transceiver, (Figure 1), is a compact, spread spectrum wireless
module designed for license-free operation in the 902-928 MHz frequency
range. It is contained on one double-sided circuit board with all necessary
components and RF shielding included. It need only be protected from direct
exposure to the weather and is designed for rugged service in extreme
temperature environments. The transceiver has full over-the-air compatibility
with standard (non-OEM) TransNET 900TM transceivers manufactured by
MDS.

All transceiver programming is performed via a connected PC terminal. No
jumper settings or manual adjustments are used to configure the transceiver
for operation.

Invisible place holder

Figure 1. TransNET OEM™ Transceiver

The transceiver employs Digital Signal Processing (DSP) technology for
highly reliable data communications, even in the presence of weak or
interfering signals. DSP techniques also make it possible to obtain
information about the radio’s operation and troubleshoot problems, often
eliminating the need for site visits.

Using appropriate software at the master station, diagnostic data can be
retrieved for any radio in the system, even while payload data is being
transmitted. (See “Network-Wide Remote Diagnostics” on Page 55.)

MDS 05-3946A01, Rev. A TransNET OEM Integration Guide 1

2.1 Transceiver Features

The OEM transceiver is designed for easy installation and flexibility in a wide
range of wireless applications. Listed below are several key features of the
transceiver which are described in more detail later in this guide.

• 128 frequencies over 902–928 MHz, subdivided into eight frequency
zones

• Configurable operating zones to omit frequencies with constant
interference

• 65,000 available network addresses to enhance communications
security

• Network-wide configuration from the master station; eliminates most
trips to remote sites

• Data transparency–ensures compatibility with virtually all
asynchronous data terminals

• Peak-hold RSSI, averaged over eight hop cycles

• Operation at up to 115,200 bps continuous data flow

• Store-and-Forward repeater operation

• Data latency typically less than 10 ms

• Same hardware for master or remote configuration

• Supports RS/EIA-232 or RS/EIA-485 interfaces (factory configured)

• Low current consumption—nominal 8 mA in “sleep” mode. Ideal for
solar/battery powered applications.

NOTE:

Some features may not be available on all units, based on the options pur­chased and the regulatory constraints for the region in which the radio will op­erate.

2.2 Model Configuration Codes

The model number code is printed on the radio module, and provides key
information about how it was configured when it left the factory. See Figure 2
for an explanation of the model number codes. (Note: This information is
subject to change and should not be used for ordering additional products.
Your factory representative can assist you with product ordering.)

2.3 Spread Spectrum Transmission

The transceiver “hops” from channel to channel many times per second using
a specific hop pattern applied to all radios in the network. A distinct hopping
pattern is provided for each of the 65,000 available network addresses,
thereby minimizing the chance of interference with other spread spectrum
systems.

In the USA, and certain other countries, no license is required to install and
operate this type of radio device, provided RF power and antenna gain
restrictions are observed. In the USA and Canada, a maximum of 36 dBm
Effective Isotropic Radiated Power (EIRP) is allowed. The factory offers a set
of approved antennas with special connectors for this radio. Substitutions that
would void the compliance of the device are not permitted.

2.4 Typical Applications

Multiple Address Systems (MAS)

This is the most common application of the transceiver. It consists of a central
control station (master) and two or more associated remote units, as shown in

Figure 3. This type of network provides communications between a central

host computer and remote terminal units (RTUs) or other data collection
devices. The operation of the radio system is transparent to the computer
equipment. This application provides a practical alternative to traditional
(licensed) MAS radio systems.

Tail-End Link to an Existing Network

A tail-end link is often used to extend the range of a traditional (licensed)
MAS system without adding another licensed radio. This might be required
if an outlying site is blocked from the MAS master station by a natural or
man-made obstruction. In this arrangement, a spread spectrum transceiver
links the outlying remote site into the rest of the system by sending data from
that site to an associated transceiver installed at one of the licensed remote
sites—usually the one closest to the outlying facility. (See Figure 5).

As the data from the outlying site is received at the associated transceiver, it
is transferred to the co-located licensed radio (via a data crossover cable) and
is transmitted to the MAS master station over the licensed channel.
Additional details for tail-end links are given in Section 7.2 (Page 25).

Figure 5. Typical Tail-End Link Arrangement

Store-and-Forward Repeater

Similar to a Tail-End Link, Store-and-Forward (SAF) offers a way to
physically extend the range of a network, but in a simplified and economical
manner. SAF operates by storing up the data received from one site, and then
retransmitting it a short time later. Figure 6 shows a typical SAF repeater
arrangement.

SAF operates by dividing a network into a vertical hierarchy of two or more
sub-networks. Extension radios (designated as

MODE X

) serve as single-radio
repeaters that link adjacent sub-networks, and move data from one
sub-network to the next. Additional information on SAF mode is provided in

“Store & Forward (SAF) Operation with Extension Radios” on Page 26.

3.0 BENCHTOP SETUP & EVALUATION

As an Integrator, your first task is to verify that the OEM module will function
as intended with the host equipment. This section describes how to test the
unit for operation with host devices such as RTUs, PLCs and similar gear. It
covers the steps for making interface connections, powering up the
transceiver, and setting configuration parameters using a connected PC.

Evaluation of the module is best performed in a controlled environment, such
as a shop or lab facility where you can readily test various hardware and
programming configurations and observe the effects of these changes before
final installation.

Once you are satisfied that the transceiver module operates properly on the
bench, you can plan the installation of the module inside the host device and
be assured of proper operation in the field.

3.1 Evaluation Development Kit (P/N 03-4053A01)

The Evaluation Development Kit is designed to assist integrators who will be
working with the transceiver in a benchtop setting. The kit contains the
following:

• Two OEM Transceiver modules (configured for TTL, or RS-232/485
operation, as requested)

• Two Evaluation Development boards (P/N 03-4051A01)

• Interface Cables

• Two whip antennas

• Two 12 Vdc power supplies

• TransNET Support CD containing software for programming &
diagnostics

MDS 05-3946A01, Rev. A TransNET OEM Integration Guide 7

Evaluation Board

A key part of the Evaluation Development Kit is the Evaluation Board shown
in Figure 7. It contains a 16-pin header connector (J2) that mates with female
connector J3 the OEM transceiver board. It carries all signals (except RF)
onto the Evaluation Board. Table 2 lists the basic pin functions of J2. For
more detailed pinout information, including the differences between TTL and
RS-232/485 configured radios, refer to Section 13.1 on Page 59.

The Evaluation Board provides convenient connection points for diagnostics,
payload data, and DC power. Each of these connectors are discussed in this
section. The board also includes a series of test probe points to the left of J2.
These may be used for monitoring logic signal activity with a multimeter or
oscilloscope. The probe points are identified by printed markings on the
board.

The transceiver board’s RF/Antenna connection is

not

brought onto the
Evaluation Board by the 16-pin header. The antenna connection is always
made at J200 on the transceiver module using a male MMCX-type connector.

3.2 Cable Connections for Benchtop Testing

There are four basic requirements for operating the transceiver and evaluation
board in a benchtop test environment. They are:

• Adequate and stable primary power

• A proper antenna system or RF load (50 Ohms)

• The correct interface wiring between the transceiver and the connected
DTE device (RTU, PLC, etc.)

• A connected PC terminal to read/set transceiver parameters.

Figure 9 shows a typical setup for bench testing an OEM Transceiver. Two

such setups will be required if you intend to establish over-the-air
communications with another OEM transceiver.

DAMAGE

Do not apply DC power to the transceiver without first
attaching a proper RF load, or the transceiver may be
damaged.

Diagnostic Connection (J4)

J4 is an RJ-11-6 modular connector used to connect the evaluation
board/transceiver to a PC terminal for programming and interrogation. An
RJ-11 to DB-9 Adapter Cable (Part No. 03-3246A01) is required for this
connection. If desired, an cable may be constructed for this purpose as shown
in Figure 10. Only Pins 4, 5, and 6 of the RJ-11 connector should be used.
Pins 1, 2, and 3 are reserved for factory test purposes.)

The data parameters of the diagnostics port are as follows: 8 data bits, 1 stop
bit, and no parity. It automatically configures itself to function at 1200, 2400,
4800, 9600, 19200, 38400, 57600, and 115200 bps, as required.

Diagnostic Communication Modes

Two methods may be used to communicate with the radio’s diagnostic port:

•

Terminal Interface

—The PC is used in its basic terminal emulation
mode, (i.e., HyperTerminal session) and commands are issued as simple
text strings.

•

Radio Configuration Software

—Proprietary software from MDS that
runs under the Windows operating system. It provides a graphical user
interface with “point and click” functionality. The program is included
on the

TransNET Support Package

CD shipped with every radio order.

Both of these control methods are described in more detail in the section titled

“PROGRAMMING REFERENCE” on Page 34. This section also includes a

chart listing all commands for the OEM transceiver.

MDS 05-3946A01, Rev. A TransNET OEM Integration Guide 11

Data Connector (J5)

J5 on the Evaluation Board (Figure 11) is the data interface for the
transceiver. It is used to connect the transceiver to an external DTE terminal
that supports the EIA/RS-232 or EIA/RS-485 format, depending on how the
radio hardware was configured at the factory. The data connector supports
interface data rates of 1200, 2400, 4800, 9600, 19200, 38400, 57600, and
115200 bps (asynchronous only). The connector mates with a standard DB-9
plug available from many electronics parts suppliers.

Data Wiring Connections

The connections made to J5 will depend on the requirements of the DTE
device being used with the transceiver, and the operating functions that you
require. Only the required pins for the application should be used. Do not use
a straight through “computer” type cable that is wired pin-for-pin.

Typical RS/EIA-232 applications require the use of Pin 2 (receive
data—RXD) and Pin 3 (transmit data—TXD). Additionally, some systems
may require the use of Pin 7 (Request-to-send—RTS). If hardware flow
control is desired, Pin 7 (RTS) and Pin 8 (CTS) may also need connection.

Table 3 gives pin details for radios configured for RS/EIA-232 service.
Table 4 gives details for radios configured for RS/EIA-485 service.

Jumper Block J1 (DC Power Configuration)

Jumper J1 does not normally require any change by the user.

The jumper is
used to configure the board for the proper voltage level applied to the
transceiver module.

Both

jumper plugs are normally installed on J1. The plug connecting Pins 3
and 4 may be temporarily removed to insert an ammeter in series with the DC
power line going to the transceiver. This provides a convenient way to
measure the transceiver’s current draw during bench testing.

3.3 Initial Power-Up & Configuration

When all of the cable connections described in Section 3.2 have been made,
the transceiver is ready for initial power-up. Operation begins as soon as
power is applied, and there are no manual adjustments or settings required.

To place the transceiver into operation:

1. Ensure that all cable connections are properly wired and secure. Verify

that no metallic objects are touching the underside of the evaluation board
which might cause a short-circuit.

2. Apply DC power. The GP indicator (CR6) on the transceiver board

should light continuously.

MDS 05-3946A01, Rev. A TransNET OEM Integration Guide 15

3. Using a connected PC terminal, configure the unit with the proper mode
(master or remote), network address and data parameters. See

Configuration Settings

below for programming details.

4. Observe the transceiver’s LED indicators for proper operation. Table 5 on

Page 17 shows the functions and normal indications of the LEDs.

5. Verify that the transceiver is transmitting and recei ving data (TXD, RXD)
in response to the master station and/or connected terminal device.

Configuration Settings

This section explains how to set the essential operating parameters of the
transceiver. For more information on connecting a PC terminal and preparing
it for use, refer to Section see “PROGRAMMING REFERENCE” on Page

34.

The three essential settings for the transceiver are as follows:

Mode—
Network Address—
Data Interface Parameters—

Master, Remote, or Extension

a unique number from 1–65000

bps, data bits, parity, stop bits

Follow these steps to program the transceiver:

1. Set the Mode using the

MODE M

(Master), MODE R (Remote), or MODE X

(Extension) command. (Note: There can be only one master radio in a
system.)

For Extension (SAF) radios only: If any MODE X radios are used in the
network, SAF must be turned on at the Master station. The MODE X radio
must be programmed with an Extended Address (XADDR). Units that
need to hear the MODE X radio must be programmed with an appropriate

XPRI and/or XMAP value. (See “Simple Extended SAF Network” on

Page 26 for more information.)

2. Set a unique Network Address (1–65000) using ADDR command. Each
radio in the system must have the same network address. Tip: Use the last

four digits of the master station’s serial number to help avoid conflicts
with other users.

3. Set the baud rate/data interface parameters. Default setting is 9600 bps, 8
data bits, no parity, 1 stop bit. If changes are required, use the B A UD xxxxx

abc command where xxxxx equals the data speed (1200–115200 bps) and
abc equals the communication parameters as follows:

a = Data bits (7 or 8)
b = Parity (N for None, O for Odd, E for Even)
c = Stop bits (1 or 2)

NOTE:

7N1, 8E2 and 8O2 are invalid interface parameters.

16 TransNET OEM Integration Guide MDS 05-3946A01, Rev. A

Configuring Multiple Remote Units

In most installations, the Remote radios will be programmed with virtually
the same set of parameters. This process can be streamlined by testing key
pieces of equipment—such as the Master, Remote, and any Extensions—on
a benchtop setup prior to installation. This allows you to test various
configurations in a controlled environment.

Once the evaluation network is working satisfactorily, you can save the
configuration of each unit in a data file on your PC’s hard drive through the
use of TransNET Configuration Software. You can then open the Remote
configuration file and install it in the next Remote radio. The software
prevents you from overwriting unit or other mode-specific parameters.

LED Indicators

The LED indicators are located to the right of the transceiver’s shield cover
(near J3) and show important information about status of the module. The
functions of LEDs are explained in Table 5 below.

NOTE: For the LEDs to function, they must be enabled using the LEDS ON command.

Within 16 seconds of power-up, the following indications will be seen if the
unit has been properly configured and is communicating with another
transceiver:

• GP lamp lit continuously

• DCD lamp lit continuously (if unit is synchronized with another station)

• Remote radio(s) transmitting data (TXD) and receiving data (RXD) with
another station.
