Signal Names
Signal names used for the FP's serial interface 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 connector.
For example, pin #2 'RD' should be connected to the 'RD' input terminal
on the FP's connector.
Refer to section "2-4 Option Cable Pin Diagrams" for information about
each signal's direction.

• Since all serial interface signals are the same on the PC side, use a
straight cable to connect the FP to the PC.
• The GND terminal is the signal ground. Be sure to connect the GND
terminal to other unit’s SG (signal ground).
