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
denotes the data speed
(300–115200 bps) and
abc
denotes 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 for this transceiver.
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, Remote, and any Extensions—on
a benchtop setup prior to installation. This allows you to test various config-
urations 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 through the use of
TransNET Configuration Software . You can then open the Remote configu-
ration file and install it in the next Remote radio. The software prevents you
from overwriting unit or other mode-specific parameters.
3.2 Tail-End Links
A tail-end link is established by connecting an MDS TransNET Series radio
“back-to-back” with another identical 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. (
Figure 4 on Page 5 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
Figure 11 .
