To connect the M220nx to the CMnet
1. Turn the M220nx’spowerswitchoff.
2. Set the CMnet mode (legacy or ARC156
CMnet) using the Comm Select jumper.
3. If communicating on a legacy CMnet, set
the Baud Select jumper for either 9600 bps
or 38.4 kbps.
4. ChecktheCMnetwiringforshortsand
grounds.
5. Connect the CMnet communication wires
to the M220nx CMnet terminals (see
Figure 1 on page 2 for location). Follow
the same polarity used throughout the rest
of the CMnet.
6. Turn the M220nx’spowerswitchon.
Communicating with the
Wo r k s tat i o n
You can connect a workstation or portable
computer directly to the M220nx module
using an APT and the module’sAccessport
(see Figure 3). This type of connection can be
used to troubleshoot the module or transfer
memory. If you are using an ARC156 CMnet,
you can receive colors while connected to a
module’sAccessportifagatewaymoduleis
on the CMnet. You cannot receive alarms
through the Access port, however.
The Access Port’sbaudrateisdeterminedby
the Baud Select jumper on the module.
1. Connect the computer’s serial port to the
EIA-232 port of the APT using a standard
straight-through serial cable.
2. Set the APT’s Mode Select switch.
• On an ARC156 CMnet, use the TTL
setting.
• On a legacy CMnet, use the 485 setting.
3. Connect the Access Port of the APT to the
Access Port of the module.
4. In SuperVision, define the connection type
using Table 1.
