Connecting trigger input
To use multi-head scan mode, connect the trigger input to the N-400 only, instead
of to each BL series unit.
2.2.2 Connecting RS-232C
Pin assignment
Pin No. 25 is used for a 5 V power supply output. Do not connect this termi-
nal to the ground terminal or any other terminal when it is unused. Doing this
may damage the N-400 or the external device connected to this terminal.
RS-232C cable connections
■ Connecting personal computer
• Connecting the computer with 25-pin • Connecting IBM PC
A commercially-available straight cable (D-sub 25 pin - 25 pin, or D-sub 25 pin - 9
pin) can be used.
