the module may not work properly.
1. Turn the module's power off. This
prevents the module from being powered
up before the proper voltage is verified.
2. Make sure the 24VAC power source is off.
3. Connect the power wires to the module's
power terminals labeled Ground and
24VAC (see Figure 1 on page 2 for
location).
4. Apply power to the transformer.
5. Make sure that 24VAC is present at the
module's power input terminals.
6. Set the module's address. Refer to
"Addressing" on page 3 for details about
setting the address.
7. Turn the module's power switch on.
When the module turns on, the Run and
Power LEDs turn on. The Run LED begins
blinking and the Error LED turns off. See
Table 7 on page 10 to troubleshoot the
LEDs. If the module does not respond, call
Technical Support at (770) 429-3002.
CMnet Communications
The M4106nx module 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 an ARC156
CMnet, use an A3ARC156 wire available
from:
Magnum Cable Corporation
Cleveland, OH 44110-0500
(800) 421-0820
Revised 3/29/00 • M4106nx
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 ARC156
CMnet Wiring Technical Instructions.
1. Be sure the module's power is off before
wiring it to the CMnet.
2. Check the network communication wiring
for shorts and grounds.
3. Connect the CMnet wires to the module's
screw terminals as shown in Figure 3. Be
sure to follow the same polarity as the rest
of the CMnet.

4. Make sure the module is configured for
the correct baud rate. All modules on the
CMnet must use the same baud rate.
On an ARC156 CMnet (156 kbps), set the
CMnet Mode jumper to ARC156 (see
Figure 4 for the switch's location).

Figure 4. Using an ARC156 CMnet
If you are using a legacy CMnet (9600 bps
or 38.4 kbps), set the CMnet Mode jumper
to Legacy 9600/38.4k, and use the baud
rate DIP switch to determine the baud rate
(see Figure 5 for the switches' locations).
