Termination
Termination of the RIO network requires a terminating resistor at each end of
the network. A termination switch is provided on the front of the interface board.
Set the switch to “ON”, if termination is required. If external terminators are
used, the switch must be in the off position.
Configuration Switches
On an A-B Remote I/O network, each node must be assigned its own unique Rack Address. The
Rack Address is a value between 0 and 59 used to identify each node. The Rack Address and
Baud Rate are set using the DIP switches on the front of the module.
These switches must be set before power is on and cannot be changed during operation.
