Using the S6104 on an ARC156
Segment
When communicating at 156 kbps, the
network segment uses a unique
implementation of the industry standard
BACnet-over-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 network
communications. When using an ARC156
network, use an A3ARC156 wire available
from:
Magnum Cable Corporation
Cleveland, OH 44110-0500
(800) 421-0820
When the CMnet Select jumper is set to
ARC156, the CMnet port is connected to an
ARCNET processor, enabling the S6104 to
communicate on an ARC156 network
segment. Communication speed is 156 kbps
regardless of the Baud Select jumper setting
(see Table 1).

Using the S6104 on a Legacy CMnet
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.
When the CMnet Select jumper is set to
Legacy, the module communicates on a
legacy CMnet at the baud rate set by the Baud
Select jumper (see Table 1). The Port Select
jumper must also be set to Access.

NOTE Setting the CMnet jumper to Legacy
disables the industry standard BACnet-over-
ARCNET (ARC156) protocol for the network
segment and enables the proprietary ALC
CMnet protocol.
Connecting the S6104 to the
Network
Before connecting the S6104 to the CMnet, be
sure the S6104's power is off.
1. Set the CMnet mode (ARC156 or legacy
CMnet) using the CMnet Select jumper.
2. If communicating on a legacy CMnet, set
the Baud Select jumper for either 9600 bps
or 38.4 kbps.
NOTE All modules on the CMnet must
use the same baud rate.
3. Set the Port Select jumper:
• On a legacy CMnet, set the Port Select
jumper for Access.
• On an ARC156 CMnet on a WebcTRL
system, set the Port Select jumper for
LogiStat.
• On an ARC156 CMnet on a
SuperVision system, set the Port
Select jumper for either Access or
LogiStat depending on which port will
be used for serial communications
(see "Communicating with the
Workstation Using SuperVision" on
page 6).
4. Check the network communication wiring
for shorts and grounds.
5. Connect the CMnet wires to the module's
screw terminals as shown in Figure 3 on
page 6. Be sure to follow the same
polarity as the rest of the CMnet.
