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 APT’s Access Port to the
module’s Access Port.
4. In SuperVision, define the connection type
using Table 2.
Formatting the Module
When 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. Make sure
the module’s address switches are not set
to ‘0 0’.
2. Press and hold the Format button (see
Figure 1 on page 2 for location). While
continuing to hold the Format button, turn
the module’s power on.
3. Continue to hold the button until the Error
LED flashes three times in sync with the
Run LED.
4. Release the Format button.
5. Transfer memory to the module. Refer to
“Transferring Memory” on page 6.
