Serial interface
specifications
This unit is equipped with a serial control interface
conforming to RS-232C standards, allowing it to be
connected to a computer with either a 9-pin or a 15-pin
D-Sub connector. The connector to be used can be
switched at Initial Settings  Options  Serial Port
(page 47).
Caution
• It is not possible to access the 9-pin and 15-pin
connectors simultaneously.
• Both the 9-pin connector and the 15-pin connector
use inch screw threads.
The connectors' pin layouts are as shown below.

Control functions

(a) Serial control
TxD, RxD and DTR
Serial control interface conforming to RS-232C
standards.
(b) Extend terminals
SW1, SW2, SW3, SW4, SW5, SW6, SW7 and SW8
This unit can be controlled by connecting switches to the
exterior of these pins.
(c) External power supply control
This unit's power can be turned on and off using the
interface connector's power pin.
Power off control is not possible when operation of the
buttons on the main unit's front panel or remote control
unit is locked.
• When power is off (in the standby mode): Power
turns on when L signal detected after H signal of
100 msec or greater
• When power is on: Power turns off (to the standby
mode) when L signal detected after H signal of
100 msec or greater
Pin input voltage: ±12 V or less; H signal level: 4.5 V or
higher, L signal level: 0.5 V or lower
