PHILIPS LTC3963/61 (E) QR31808
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.
REC START IN
Recording is started when 5 ~ 12V is applied to pin
!0.
REC OUT
Approx. 5V is applied to pin !1 during 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 !4 is shorted to
pin !5 during 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.
