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.
