1. Using the Uni/16

Connecting the UNI/16 to the U-Line

modules

The UNI/16 supports up to 16 U-Line

modules. The baud rate of the Unet is set on

the module driver Parameter page. Refer to

the U1M Module Driver document for more

information.

Automated Logic Corporation recommends a

specific wire for both power and

communications on the Unet. This wire,

which contains a pair of 14AWG wires for

power and a pair of 22AWG wires for

communication, is available from:

Magnum Cable Corporation

Cleveland, OH 44110-0500

(800) 421-0820

Product number A3U-LINE

Note that the communication wire is

unshielded. Shielded cable is not required for

the Unet.

Use the Unet connection port to connect the

UNI/16 to the U-Line modules. The Unet

connection port can make two connections to

the Unet, as shown in Figure 3. Make sure the

Unet connection port configuration jumpers

are set to UNI and EIA-485 (see Figure 4).

Make sure that all U-Line modules and the

TNPB use the same polarity throughout the

subnet. You can verify that the UNI/16 is

communicating with the subnet by making

When adding a new U-Line module to an

existing subnet, you must transfer memory to

the UNI/16 before the new card is recognized.

Connecting the UNI/16 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 on page 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 on page 5).

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/16 is

communicating on the CMnet by making sure

the CMnet transmit and receive LEDs are

active.
