Figure 3. Communication wiring

Figure 4. Unet configuration jumpers

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).

Figure 5. Setting the CMnet baud rate to 156

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).

Figure 6. Setting the CMnet port baud rate to

38.4 kbps or 9600 bps

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
