 When connecting to an external device with hardware flow control, communication
will be impossible using a cable without RTS and CTS connected. In that case,
connect RTS and CTS. This will disable hardware flow control, but will enable
communication.
• When the connector of an external device is a D-Sub 9-pin connector, pin 7
is RTS and pin 8 is CTS.
• When the AX-KO3285-320 cable is used, RTS and CTS are internally
connected and the above operation is unnecessary.
