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.
