Connecting the UNI/32 to an

ARC156, MS/TP, or Legacy CMnet

network segment

The UNI/32 supports several

communications options through its CMnet

connection port.

On a WebCTRL system, the UNI/32 can

connect to a legacy CMnet at 9600 bps or 38.4

kbps, to a BACnet-over-ARCNET network

segment at 156 kbps, or to a BACnet MS/TP

at 9600 bps or 38.4 kbps.

NOTE The UNI/32 has the ability to connect

to ARC156, BACnet MS/TP, or Legacy

networks. For maximum performance, ALC

recommends that the UNI/32 be configured

for ARC156. All modules on the CMnet must

already be downloaded with module driver

v1.2 or later to use BACnet MS/TP.

On a SuperVision system, the UNI/32 can

connect to a legacy CMnet at 9600 bps or 38.4

kbps or to a BACnet-over-ARCNET network

segment at 156 kbps.

NOTE BACnet MS/TP is not available on a

SuperVision system.

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).

Revised 11/26/01 • UNI/32

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/32 is

communicating on the CMnet by making sure

the CMnet transmit and receive LEDs are

active.

Addressing

The UNI/32 has an eight-position DIP switch

for assigning the module's address. Before

setting or changing the address, make sure

the UNI/32's power is off, since the UNI/32

only reads the address when the module is

turned on.
