Make sure that all T-Line or U-Line modules
and the TNPB use the same polarity
throughout the subnet. You can verify that the
UNI/59 is communicating with the subnet by
making sure the Unet transmit and receive
LEDs are active.
When adding a new T-Line or U-Line module
to an existing subnet, you must transfer
memory to the UNI/59 before the new card is
recognized.
Connecting the UNI/59 to the CMnet
When communicating on an ARC156 CMnet,
use an A3ARC156 wire available from
Magnum Cable Corp. Use a dedicated 22AWG
to 18AWG twisted pair wire for legacy CMnet
(EIA-485) wiring. For more information about
CMnet wiring, refer to the
Technical Handbook
or to the
ARC156 CMnet Wiring Technical
Instructions.
To set the baud rate at 156 kbps (when using
an ARC156 CMnet), set the baud rate jumper
to Arc156 (see Figure 5).
To set the baud rate at 38.4 kbps, set the baud
rate jumper to 9600/38.4K, and set the first
switch on the eight-position DIP switch to
38.4K (see Figure 6).
To set the baud rate at 9600 bps, set the baud
rate jumper to 9600/38.4K, and set the first
switch on the eight-position DIP switch to
9600 (see Figure 6).
You can verify that the UNI/59 is
communicating on the CMnet by making sure
the CMnet transmit and receive LEDs are
active.
Addressing
The UNI/59 has an eight-position DIP switch
for assigning the module’s CMnet address.
Before setting or changing the address, make
sure the UNI/59’s power is off, since the
