The NCM-W provides two sets of switches to simplify network set-up. Default settings for BC-200 networks are
shown in the diagram below.

To enable ground fault detection, set SW103 for Channel A; SW101 for Channel B, to the ON position
To activate the on-board end-of-line resistors, set SW100 for Channel A; SW102 for Channel B, to the ON
position. There MUST be a functioning terminating resistor on the first and last node/repeater of a wire
segment (between 2 nodes). This means that in a ring configuration each NCM in the ring
MUST
have
terminating resistors enabled for both channels.
