Concerning Signal Names
Signal names used for the serial interface on FP units are designed to match the
pin order used on most PC serial interfaces, so that a straight cable can be used to
connect the two. Therefore, connect each pin's signal to the same signal name on
the PC side.
For example, pin #2 'RD' should be connected to the 'RD' input terminal on the
PC's connector.
Refer to section "2.4 Cable Diagrams" for each signal's direction.

RS-232C Interface
RS-232C Interface Pin Assignments and Signal Names
Connector:
Dsub 9 pin female
Connector set screw: Inch type (4-40)
Cable:
SIO cable manufactured by Digital Electronics Corporation of Japan
(FP61V-IS00-O)
*1 CD, DTR, and DSR are connected together inside of the FP.
If a cable other than the specified RS-232C cable is used, product perfor-
mance cannot be guaranteed due to the possibility of noise interfering
with the FP unit's operation.
