4.9 Connecting the Remote I/O Unit

The RIO-M connector is used to connect the remote I/O unit. Connect the R211 cable from the RIO-M
connector on the control unit to RIO1 on the remote I/O unit.
When connecting multiple remote I/O units, connect the R211 cable from the RIO2 connector to the
RIO1 connector on the next remote I/O unit.
Connect the terminator (R-TM) to RIO2 connector on the final remote I/O unit. Use the accessories for
the connectors and contacts when manufacturing the R211 cable. If the accessories are insufficient,
prepare the CN221 one end connector set (optional, with one end).
