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 Section 3.0, Benchtop Setup

and Evaluation 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 Microwave Data Systems Inc.

• Use an MCX-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

MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 1

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 2.4 GHz 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

TM

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 56.)

2 TransNET OEM 2.4 Integration Guide MDS 05-xxxxA01, Rev. 01

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.

• Three operating bands in the 2.4006 to 2.4820 GHz spectrum

• 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 pur-

chased and the regulatory constraints for the region in which the radio will op-

erate.

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.)

MDS 05-xxxxA01, Rev. 01 TransNET OEM 2.4 Integration Guide 3

Figure 2. Model Number Configuration Codes

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).

Invisible place holder

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

The Evaluation Development Kit is designed to assist integrators who will be

working with the transceiver in a benchtop setting. The kit contains the
