RIO Drop Addressing
Overview Each RIO drop adapter on the network must be assigned a unique address number.
The RIO processor uses this drop address to send I/O module data or ASCII
message data to the proper adapter. The physical location of an adapter on the
network has no bearing on its address or on the data throughput, making the RIO
network a true bus architecture.
Setting Drop
Addresses
RIO drop adapters have switches on them that are used to set the unique RIO drop
addresses and ASCII port addresses (if ASCII devices are supported at the drops).
DIP switches are used on the 984 type adapters, and rotary switches are used on
Quantum adapters. Consult the hardware documentation for location of the switches
and appropriate settings.
