IMPORTANT NOTE

The 4-position RS485 DIP Switch (S2) on the PMC PCB of the C-More Controller must be set as

follows:

1) The termination (TERM) and bias (BIAS1 & BIAS2) DIP Switches of S2 must be set to DISABLE.

2) If an Oxygen Sensor is connected to the C-More Controller, switch R1 (see below) should be set

to DISABLED (down). If an Oxygen Sensor is NOT connected to the C-More Controller, it should

be set to ENABLED (up). Improper setting of R1 may result in error messages.

Instructions for accessing the PMC PCB and this DIP Switch can be found in Section 4.3 of ModBus

manual GF-114.
