Western Reserve Controls WRC-CANX-xx Series 3

PUB 14.0 User’s Manual

Important: Per the DeviceNet and SDS specs -- do not terminate devices on drop lines.

An appropriate terminating resistor kit, WRC part number RM121DN, which satisfies both DeviceNet

and SDS specs, is included with your Extender.

Note: The WRC-CANX Series 3 family is configured at the factory with 2 internal terminating

resistors on each network – one for Network A and one for Network B – using jumpers W1 and W2. If these

are used in a trunk line, no other terminators should be placed at the CANX that end of the network.

Note: If the CANX is used on a drop line, the internal terminating resistor should be removed on

Network A – the drop line directly from the trunk line.
