Signal Names
Signal names used for the RS-232C Interface are designed to match the pin order
used on most PC RS-232C interfaces, which allows a straight cable to be used to
connect the two. Therefore, connect each pin's signal to the same signal name on
the PC side.
For example, the FP unit connector's pin #2 'RD' should be connected to the PC
connector's 'RD' terminal. For detailed signal direction information,
