PHILIPS LTC3924/62 (E) QR34071
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 !5 or !6 (ground) through the switches.
Note: Do not apply a voltage to pin q, !5 or !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 !5 or !6.
Note: Do not apply a voltage to pin t, !5 or !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.
REC START IN
Recording is started when 5-12V is applied to pin !0.
