4.1 - CAN Communications
The CAN port is provided via the single 8-position modular jack labeled
“CAN”. It may be used to communicate with other OCS products using
Horner’s CsCAN protocol. Additionally, remote expansion I/O such as
SmartRail, SmartBlock, and SmartStix may be implemented using the
CsCAN protocol.
Termination for the CAN port may be enabled from the System Menu or
System Register. This should only occur if the X4 is at either end of the
CAN network. Only the two devices on either end of the CAN network
should be terminated.
