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.
