1. PRODUCT OVERVIEW

This document provides the information
required for the selection, installation, op­eration and maintenance of the

DATARADIO

T-96H radiomodem.

1.1 Intended Audience

This document is designed for use by engi­neering design, installation, and mainte­nance personnel.

1.2 Introduction

This chapter provides the information nec­essary to identify and assess the capabilities
of the T-96H. Connection and operation are
also described.

1.3 General Description

The T-96H is a transparent real-time radio­modem designed primarily for SCADA and
telemetry use. The T-96H is available in
different versions according to radio fre­quency. Common features to all versions
include:

• Data speeds of 4800 to 19200 b/s

(9600 b/s maximum in half channels)
using standard RS-232 interface.

• Built–in 8 channel synthesized radio

transceiver for VHF, UHF and
900 MHz.

• Power output of 1W to 5W (software

controlled).

• Half duplex or simplex operation.

• Transmit switching via RTS.

• On-line diagnostics monitoring

• Offline local and remote diagnostics.

• Compatible with

for base station or repeater use.

• Compatible with any

DATARADIO

Interoperability Standard

equipment for data rate up to 9600 b/s.

1.4 Physical Description

The T-96H consists of a logic PCB (which
includes the modem circuitry) and a sepa­rate radio module. The two boards plug di­rectly together and slide into the rails of an
extruded aluminum case. The front panel
includes the DE-15 data connector and a
SMA antenna connector, as well as three
LED indicators. Power connections are
made through the DE-15 data connector.
The unit is not hermetically sealed and
should be mounted in a suitable enclosure
where dust and/or a corrosive atmosphere
are anticipated. There are no external
switches or adjustments. Operating pa­rameters are set using software.

Channel selection may be done using an
internal DIP switch, by strapping the appro­priate pins on the DE-15 data connector, or
by selecting the desired channel using the
T96HRSS or the OFLNDIAG.

1.5 Configuration

Operating characteristics of the T-96H are
configured by means of

(T96HRSS - p/n 085 03250-xxx)

ware

available from your sales representative.
Also available is the
software (OFLNDIAG) and the

agnostics Monitor

access to offline diagnostics & commands
(local and remote) and online diagnostics
monitoring with or without a T-Base. Both
programs are MSDOS based and will run on
any 486 or higher PC (2 Megabytes memory
required).

The T-96H requires the use of the
T96HRSS for both configuration and ad­justment.

1.8 Product Warranty

Warranty information may be obtained by
contacting your sales representative.

1.9 Replacement Parts

This product is normally not field service­able, except by the replacement of complete
units. Specialized equipment and training is
required to repair logic boards and radio
modules.

Contact Technical Support for service in­formation before returning equipment. A
Technical Support representative may sug­gest a solution eliminating the need to return
equipment.

1.9.1 Factory Repair

When returning equipment for repair, you
must request an RMA (Returned Material
Authorization) number. The Tech Support
representative will ask you several questions
to clearly identify the problem. Please give
the representative the name of a contact per­son who is familiar with the problem,
should questions arise during servicing of
the unit.

Customers are responsible for shipping
charges for returned units. Units in warranty
will be repaired free of charge unless there
is evidence of abuse or damage beyond the
terms of the warranty. Units out of warranty
will be subject to service charges. Informa­tion about these charges is available from
Technical Support.

1.10 Diagnostics and
Remote Commands

Diagnostics and remote commands are
processed using the T96H Offline Diagnos­tics software (OFLNDIAG). Diagnostics
can be monitored using the T96H Online
Diagnostics Monitor program (ONDMON).

DATARADIO

RNET 9600.

Offline diagnostics. Information is sent by a

specific unit in response to an inquiry
by the master or monitoring station.

Remote commands. Commands may be sent

by the master or monitoring station to
any specific remote unit.

1.10.2 Online Diagnostics

Online diagnostics (statistics) require the
use of a network configuration such as that
specified in section 1.11.2. or 1.11.4 Online
diagnostics do not interfere with normal
network operation. The following informa­tion is gathered:

• Supply voltage

• Internal temperature

• Forward and reverse power in watts

(T96S models only)

• Received signal strength in dBm

Each T-96H can accumulate these statistics
for the last 15 stations heard. The accumu­lated values may be displayed using the
OFLNDIAG or dynamically monitored by
the Online Diagnostics Monitor program
(ONDMON).
