EXTERNAL CONNECTIONS (Continued)

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±2 ms

REC START IN

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

REC OUT

Approx. 5V is applied to pin !1during recording. The output impedance is 4.7 kohm at this time. The output stops when recording is interrupted.

LOW TAPE OUT

During recording, when the digital counter counts up to “21600”, approx. 12V is applied to pin !2. Use this function as a reference to judge when the tape is near its end.

The output stops when a TAPE END RESET pulse is input or the EJECT button is pressed.

Note: The output impedance is approx. 100 ohm.

REMOTE IN

This VCR can be remote controlled when the follow- ing circuit is connected to pin !3.

The above resistance values have a tolerance of ±2%.

REC CHECK IN

Recording can be checked when pin !4is shorted to pin !5during recording mode. The recorded ma- terial is played back for several seconds so that you can check whether recording is made normally or not.

WARNING OUT

When an abnormality has occurred in this VCR, approx. 5V is output to pin y to warn the user.

TIME ADJUST

When two or more of this VCR model are used, con- nect via pins i. 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 “2:00:05” is reached, the VCR set to MAS- TER 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: 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.
