• 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, con-

nect 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.

Optional Cable Diagrams (page2-3)

• If a cable other than the specified RS-232C cable is used, product performance

cannot be guaranteed due to the possibility of noise interfering with the FP unit's

operation.
