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 BAUD xxxxx abc command (Page 29). It should be
set to the highest speed that can be sent by the data equipment in the system.
(The transceiver supports 300 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 (Page 41) can be used to omit them
from the hop pattern. You should also review Section 3.3, A Word About
Radio Interference, when dealing with interference problems.
6.0 RADIO PROGRAMMING
There are no manual adjustments on the radio. Programming and control is
performed through a PC connected to the radio’s DIAG connector.
6.1 Radio Programming Methods
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 the tables
found in “User Commands” on Page 23. The PC must be connected to the
radio’s DIAG connector using an RJ-11 to DB-9 Adapter Cable (MDS P/N
03-3246A01). If desired, a cable of this type may be constructed using the
information shown in Figure 21 on Page 69.
Once connected, communication (baud rate) is established through the
command interface. To access the command interface, press the key,
followed by one or more keystrokes (delivered at about half-second
intervals), until the “>” prompt is displayed.
NOTE: The DIAG port (RJ-11 connector) uses 8 data bits, 1 stop bit, and no parity. It
can automatically configure itself to function at 1200, 2400, 4800, 9600, 19200,
38400, 57600, and 115200 bps. [Default:
BAUD = 9600]
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 the diagnostic
link mode and enter the 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 MS Windows™-based MDS TransNET Configuration Software
(P/N 06-4059A01) is designed for use with a PC connected to the radio’s
DIAG connector through an RJ-11 to DB-9 cable assembly (MDS Part No.
03-3246A01). A cable of this type may be constructed using the information
shown in Figure 21 on Page 69.
