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 

!1

(ground) through the switches.

Note:  Do not apply a voltage to pin 

q

or  

!1

.

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 SET 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 SET 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 SET 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 RST
The TAPE END OUT function can be turned off when
pin 

t

is shorted to pin 

!1

.

Note:  Do not apply a voltage to pin 

t

or 

!1

.

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

.

ALARM REC RST
When pin 

e

is shorted to pin 

!1

during alarm

recording, alarm recording is stopped and the origi-
nal mode be restored.
