EXTERNAL CONNECTIONS

ALARM IN

You can connect an alarm switch with a resistance of 1 kohm or less or a door sensor. Connect pin q to pin !5or !6(ground) through the switches.

ALARM IN

GND

q

!5or !6

 

 

 

 

 

 

 

 

Note: Do not apply a voltage to pin q, !5or !6.

ALARM OUT

Approx. 12V is applied to pin w during an alarm recording.

Notes:

•When you have selected “PULSE” in the “ALARM OUT” menu in the ALARM display, approx. 12V pulses will be applied to the output after the alarm recording ends.

•When you have selected “DURATION” in the “ALARM OUT” menu in the ALARM display, no voltage is applied after the alarm recording ends.

•The output impedance is approx. 100 ohm.

TAPE END OUT

Approx. 12V is applied to pin r when the tape reaches the end.

Notes:

•This does not operate when you have selected “REWIND, RE-REC” in the “RECYCLE FUNC- TIONS” menu in the ALARM display or you have selected “REWIND, STOP IF ALARM” and no alarm recording has been made.

•The output impedance is approx. 100 ohm.

TAPE END RESET

The TAPE END OUT function can be turned off when pin t is shorted to pin !5or !6.

Note: Do not apply a voltage to pin t, !5or !6.

TIME ADJUST

When two or more of this VCR model are used, con- nect via these terminals. With only one VCR, specify TIME ADJUST: MASTER, in [OPTIONS] items on the CLOCK SET display. Specify TIME ADJUST: SLAVE (default setting at the factory) for all other VCRs. Each time “2:00:05A” is reached, the VCR set to MASTER transmits pulses for adjustment to the VCRs set to SLAVE. When the VCRs set to SLAVE receive these pulses, their clocks will adjust to the same time as the clock in the VCR set to MASTER.

Note:

•Do not connect any device to pin e , y , u , !1,

!2, !3, !4.

•Be sure to set only one VCR to MASTER. If no VCR is set to MASTER, or two or more VCRs are set to MASTER, the TIME ADJUST function will not operate normally.

CAMERA SW OUT

Pin o outputs the following signal each time a one- field image is recorded. You can combine this with a video camera switcher which can be controlled externally.

The output timing can be specified using the SELEC- TION MENU screen.

4.5~5.5V

0~0.4V

5±2ms

REC START IN

Recording is started when 5-12V is applied to pin !0.
