(1) Specification
An SIO expansion board is a D-sub, 15-pin interface used for both RS232 and RS422 connection.
The terminal assignments allow selection of RS232, RS422 or RS485 in accordance with the
wiring. (The controller is shipped with a joint cable appropriate for the selected communication
method.)
