The above setup example assumes that the RS-232C baud rate is 115200 bps. If modifying this
setup, refer to the “With Single Satellite I/O Box” in the previous page.
Connect the first I/O Box and the PC with a cross-type RS-232C cable.
Then connect the C-OUT terminal of the I/O Box connected to the PC to the C-IN terminal of
the other I/O Box via the RS-422 cable. Connect the rest of I/O Boxes so that the one with the
terminator setting is the last under daisy-chain.
