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
