2.4.3 SIO Interface Cable Pin Connections
Signals and signal names used with the FP and the SIO cable (optional cable) are the same as those used for
PCs. Also, the same pin is used on both sides of the optional cable so that you can connect the cable regardless
of the cable direction.
Inch is used for the pitch of the connector screw on the PC. For this reason, inch (4-40) is also used for the
pitch of the connector screw for the cable and the FP.
