3.8.1.2 Setting the PMC Board RS-485 DIP Switches Instructions

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

set as follows for use with the ProtoNode:

• The termination (TERM) and bias (BIAS1 & BIAS2) DIP Switches of S2 must be set

to DISABLE.

• 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.

Figure 3-12: C-More Controller PCB DIP Switch Settings

NOTE

If bias is needed, activate the ProtoNode bias jumpers. If

termination is needed, .activate the ProtoNode termination

jumpers as well as the termination dip switch in the last

boiler/heater’s I/O box at the end of the RS485 daisy chain.

If an Oxygen Sensor is attached to the C-

More Controller, set R1 to DISABLED

(down). If an Oxygen Sensor is NOT used,

set R1 to ENABLED (up). Factory default

setting is ENABLED.
