Communications Wiring
The LGC can connect to the CMnet at 9600
bps, 38.4 kbps, or 156 kbps. When
communicating at 156 kbps, the CMnet uses a
unique implementation of the industry
standard ARCNET protocol called ARC156.
For a summary of the differences between
ARCNET and ARC156, please refer to ARC156
CMnet Wiring Technical Instructions.
Use the appropriate wire for CMnet
communications. When using the ARC156
protocol, use an A3ARC156 wire available
from:
Magnum Cable Corporation
Cleveland, OH 44110-0500
(800) 421-0820
Use a dedicated 22AWG to 18AWG twisted
pair EIA-485) for legacy CMnet wiring. For
more information about CMnet wiring, refer
to the Technical Handbook or to ARC156
CMnet Wiring Technical Instructions.
1. Turn off the power.
2. Attach the two CMnet EIA-485
communications wires to the CMnet
Connection port labeled Net - and Net +
on the LGC (see Figure 1 on page 2). On
an ARC156 CMnet, you must also connect
the Shield.
Be sure to follow the same polarity as
used throughout the rest of the CMnet.
3. Make sure the LGC is configured for the
correct baud rate. All modules on the
CMnet must use the same baud rate.
On an ARC156 CMnet, set the CMnet Baud
Rate jumper to Baud 156K. Refer to Figure
2 for the jumper's location.

If you are using a legacy CMnet, set the
CMnet Baud Rate jumper to Baud 9600/

the first switch on the Addressing DIP
switch. Refer to Figure 3 for the switch's
location.

Addressing
The LGC's address is factory-set as control
module #1 and cannot be changed.
Transferring Memory
The LGC module stores the LGM module
driver. To transfer the module driver to the
LGC, you must use SuperVision v2.6 or later
software, and you must use FBLINK version
2.7a or later. For more information about
using SuperVision, refer to the SuperVision
User's Guide.
