When the module turns on, the Power,

Run and Error LEDs turn on and the Run

and Error LEDs begin blinking. The Error

LED then turns off. (See "LEDs" on page 9

for more information about LED signals.)

Communicating with the

UNI/32

The UNI/32 connects to the CMnet through

an EIA-485 CMnet port. A five-pin EIA-485

port provides two connections to U-cards on

the Unet. You can connect an optional

BACview

or BACview

the keypad display port (see Figure 2 on page

3).

NOTE The EIA-232 port, labeled Diag Port

in Figure 2 on page 3, is reserved for future

diagnostic capabilities. This feature is not yet

available.

You can use WebCTRL or SuperVision to

transfer memory to the UNI/32. You can

connect a portable computer running

SuperVision to the UNI/32 using the module's

Access port. For more information about

connecting to a workstation, refer to

"Communicating with the Workstation Using

SuperVision" on page 8.

Connecting the UNI/32 to the U-

cards

The UNI/32 supports up to 32 U-cards. The

baud rate of the Unet is set on the module

driver Properties page in WebCTRL or

Parameter page in SuperVision. Refer to the

appropriate 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:

Revised 11/26/01 • UNI/32

keypad display unit to

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/32 to the U-cards. 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-cards and the TNPB use

the same polarity throughout the subnet. You

can verify that the UNI/32 is communicating

with the subnet by making sure the Unet

transmit and receive LEDs are active.

When adding a new U-card to an existing

subnet, you must transfer memory to the

UNI/32 before the new card is recognized.
