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
on the Connections page. See Table 1.
Formatting the Module
If you are unable to communicate with a
module, you can, as a last resort, manually
format the module to try to restore
communication. Formatting the module
erases all memory, so you need to transfer
memory back to the module once it is
formatted.
1. Turn the module’s power off.
2. Make sure the module is addressed
correctly.
3. Press and hold the Format button (see
Figure 2 on page 3 for location).
4. While continuing to hold the Format
button, turn the module’s power on.
5. Continue to hold the button until the Error
LED flashes three times in sync with the
Run LED.
6. Release the Format button.
7. Transfer memory to the module. Refer to
“Transferring Memory” on page 6.

show the status of certain functions. Table 2
explains the Run and Error LED signals in
detail to assist troubleshooting.
Power - indicates power is being supplied to

CMnet Rx - lights when the module receives
data from the CMnet.
Unet receive - lights when the module

Unet transmit - lights when the module
transmits data to the Unet.
Diag receive - lights when the Diag Port
receives data.
