Including Instructions for
03-4053A01 Evaluation Development Kit

The steps below contain the essential information needed to place the OEM trans-
ceiver 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 “EVALUATION DEVELOP-
MENT KIT (P/N 03-4053A01)” on Page 75 for interface wiring and configuration
details.
1. Mount the transceiver module using the four holes provided.
• If possible, select a mounting location that allows viewing 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 GE MDS.
• Use a matching 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 LED should be lit continuously
• The DCD LED 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™transceiversintoexisting electronicequipment.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 trans-
ceiver, 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 operation in the 900 and 2400 MHz license-free
frequency bands. 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 transceivers manufactured by GE MDS. All transceiver program-
ming is performed via a personal computer or terminal connected to the
module. There are no manual adjustments required to configure the trans-
ceiver for operation.
Invisibleplaceholder
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 inter-
fering 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 trans-
mitted. (See “Performing Network-Wide Remote Diagnostics” on Page 61.)

chased, or the applicable regulatory constraints for the region in which the radio will op-
erate.
2.2 Factory Hardware Options
There are a number options for the transceiver assembly that must be speci-
fied at the time the order. These include: antenna connector type, data inter-
face signalling and primary power.
2.3 Data Interface and Power (J3) Options
Table 1 below lists the interface options that can be specified when the trans-
ceiver module is ordered. If you are uncertain as to the configuration of the
unit you are using, please copy the model number code from the transceiver
module and contact the GE MDS Customer Service Department for assis-
tance.

05-3946A01, Rev. C TransNET OEM Integration Guide 3
Antenna Connector (J200/J201)
The PCB has solder pads for several RF connectors with different footprints
but only one RF connector will be installed. Below is a table of connector
options available from the factory when the order is placed. We do not recom-
mend retrofitting the PCB with an alternate connector as damage to the board
could result and will void the factory warranty.
2.4 Model Number
The radio model number is printed on the label on the end of the radio’s enclo-
sure. It provides key information about how the radio was configured when it
left the factory. This number is subject to many variations depending on what
options are installed and where (country) the product is used. Contact the fac-
tory if you have questions on the meaning of the code.

2.5 Spread Spectrum Radios—How Are They Different?
The main difference between a traditional (licensed) radio and the
MDS TransNET transceiver is that this unit “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 avail-
able network addresses, thus minimizing the chance of interference with
other spread spectrum systems. In the USA, Canada, and certain other coun-
tries, no license is required to install and operate this type of radio system,
provided that RF power and antenna gain restrictions are observed.
2.6 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 2. 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.

Point-to-Point System
A point-to-point configuration (Figure 3) is a simple arrangement consisting
of just two radios—a master and a remote. This provides a half-duplex
communications link for the transfer of data between two locations.
Invisibleplaceholder
Figure 3. Typical Point-to-Point Link
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 4).
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. Addi-
tional details for tail-end links are given in Section 6.2 (Page 19).

Store-and-Forward Repeater
Similar to a Tail-End Link, Store-and-Forward (SAF) offers a way to physi-
cally 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 5 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
“SAF Operation with Extension Radios” on Page 20.

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 trans-
ceiver, 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.
NOTE: Before using the Evaluation PCB, please review the detailed information on the Eval-
uation PCB and its functions, see “EVALUATION DEVELOPMENT KIT (P/N
03-4053A01)” on Page 73.

3.1 Initial Power-Up & Configuration
When all of the cable connections described in “Cable Connections for
Benchtop Testing” on Page 75 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.
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 4
on Page 11 shows the functions and normal indications of the LEDs.
5. Verify that the transceiver is transmitting and receiving 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, refer to“User
Commands” on Page 34.
6. The three essential settings for the Transceiver are as follows:
Mode—Master, Remote, or Extension
Network Address—a unique number from 1 to 65000
Data Interface Parameters—bps, data bits, parity, stop bits
a. Set the Mode using the MODE M (Master), MODE R (Remote), or
MODE X (Extension) command. (Note that there can be only one
Master radio in a system.)

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 “SAF Operation with Extension Radios”
on Page 20 for more information.)
b. 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’s serial number to help avoid
conflicts with other users.
