c.
Set the baud rate/data interface parameters. Default setting is 9600
bps, 8 data bits, no parity, 1 stop bit. If changes are required, use the
BAUD xxxxx abc
command where
xxxxx
equals the data speed
(1200–115200 bps) and
abc
equals the communication parameters
as follows:
a = Data bits (7 or 8)
b = Parity (N for None, O for Odd, E for Even
c = Stop bits (1 or 2)
NOTE:
7N1, 8E2 and 8O2 are invalid interface parameters.
4.2 Configuring Multiple Remote Units
In most installations, the Remote radios will be programmed with virtually
the same set of parameters. This process can be streamlined by testing key
pieces of equipment—such as the Master, any Extensions, and a typical
Remote—on a benchtop setup prior to installation. This allows you to test
various configurations in a controlled environment. Once the evaluation
network is working satisfactorily, you can save the configuration of each unit
in a data file on your PC’s hard drive through the use of the MDS TransNET
Configuration Software.
Most often, there are many Remote units that will need configuring. Using the
MDS TransNET Configuration Software, you can save the sample unit’s
configuration, then open the configuration file with the program and install it
in the next Remote. The software will prevent you from overwriting unit or
mode-unique parameters.
4.3 Tail-End Links
A tail-end link is established by connecting an MDS TransNET 900 radio
“back-to-back” with another radio such as a licensed MDS x710B Series
transceiver. This can be used to link an outlying remote site into the rest of an
MAS network. (
shows a diagram of a typical tail-end link
system.) The wiring connections between the two radios in a tail-end link
system should be made as shown in
