MDS 05-2708A01, Rev. D MDS TransNET I&O Guide 17
The radio must be used only with negative-ground sys-
tems. Make sure the polarity of the power source is cor-
rect. The unit is protected from reverse polarity by an
internal diode and fuse.

Figure 14. Power Connector
(Polarity: Left +, Right –)
The power connector used with the
MDS TransNET
transceiver is similar to that used by other MDS prod-
ucts, such as the MDS 9810 and MDS x710 family. The
connectors are not equal and the use of the other style
connector may provide unreliable connections and a
spark may be created.
Only the power connector, shown in Figure 14 with
screw terminals and two retainer screws should be used
with this unit.
5. Set the radio’s basic configuration with a PC terminal connected to the
DIAG(nostics) connector via an RJ-11 to DB-9 adapter cable, MDS
P/N 03-3246A01. (If necessary, a cable of this type may be constructed
using the information shown in Figure 21 on Page 69.) For more
information on connecting a PC terminal and preparing it for use, refer to
Section 6.1 on Page 22.
The three essential settings for the Transceiver are as follows:
Mode—Master, Remote, or Extension
Network Address—a unique number from 1 to 65000
Data Interface Parameters—bps, data bits, parity, stop bits
a. Set the Mode using the MODE M (Master), MODE R (Remote), or
MODE X (Extension) command. (Note: There can be only one Mas-
ter radio in a system.)
If any MODE X radios are used in the network, SAF must be turned
on at the Master station. The MODE X radio must be programmed
with an Extended Address (XADDR). Units that need to hear the
MODE X radio must be programmed with an appropriate XPRI and/or
XMAP value. (See “SAF Operation with Extension Radios” on
Page 52 for more information.)
