Baud Rate Setting

The default baud rate setting is 19200 bps to accommodate most systems. If
your system will use a different data rate, you should change the radio's data
interface speed using the
set to the highest speed that can be sent by the data equipment in the system.
(The transceiver supports 1200 to 115200 bps.)

Radio Interference Checks

The radio operates in eight frequency zones. If interference is found in one or
more of these zones, the SKIP command
from the hop pattern. You should also review
Radio Interference, when dealing with interference problems.

6.0 RADIO PROGRAMMING

There are no manual adjustments on the radios. Programming and control is
performed through a PC connected to the radio's

Terminal Interface

A PC may be used by operating it in a basic terminal mode (for example, a
HyperTerminal session) and entering the radio commands listed in tables

the information shown in
Once connected, communication (baud rate) is established through the
command interface. To access the command interface, press the
key, followed by one or more
half-second intervals), until the ">" prompt is displayed.

The
can automatically configure itself to function at 1200, 2400, 4800, 9600, 19200,
38400, 57600, and 115200 bps.
If the DLINK setting is ON, the DIAG port will start out in Diagnostic Link mode.
This is a special protocol used to support Network-Wide Diagnostics. The pro-
cess described in the paragraph above causes the radio to exit diagnostic link
mode and enter command mode. If there is no input in command mode for 5
minutes, the DIAG port will revert back to diagnostic link mode.
PC-Based Configuration Tool
The Windows™-based MDS TransNET Configuration Software
(P/N 06-4059A01) is designed for use with a PC connected to the radio's
connector through an RJ-11 to DB-9 cable assembly (MDS Part No.
