INSTALLATION
Use coaxial cables when connecting a camera and a
monitor to this VCR.
Note: Long cable runs to distant cameras may cause
signal deterioration and/or sync discrepancies. If these
problems occur, use video line amplifiers and/or
cameras having phase-adjustable line-locked vertical
sync.
5.1
Video Connection
(Fig 4, Item 3)
Video Input - In single camera systems, connect the
camera to the Video IN BNC terminal on the VCR
rear panel. In multiple camera systems, connect the
switcher/multiplexer output to the Video IN BNC
terminal. Because multiple camera systems require
synchronization, use of cameras having line-locked
vertical sync or a genlocked master drive/sync source
is highly recommended. The use of vertical interval
switchers is also recommended.
Video Output - Connect the monitor to the Video
OUT BNC terminal on the rear panel.
5.2
Audio Connection
(Fig 4, Item 2)
Audio can be recorded at 6H, 18H, 30H speeds. To
hear the playback sound, use the 6H, 18H or 30H
speed during playback.
Audio In: Accepts an audio signal from a camera,
external sound equipment, or another recorder (Line:
–8.8 dBm, min. 47 kOhm).
Audio Out: Provides an audio output for a monitor or
another recorder (–5.8 dBm, max. 1.0 kOhm).

Using the 9-pin Terminals
(Fig 4, Item 4)
Attach the wires of the alarm switch, door sensor or
warning lamp to the 9-pin terminal by pushing in the
cable wire.
ALARM IN - You can connect an alarm input from a
switcher/multiplexer to record an alarm event on tape.
Connect input to pin 1 and ground to pin 7.
ALARM OUT - Open collector output to pin 2 during
an alarm recording. This can be used to trigger an
external device (i.e. alarm bell).
SERIES - When two or more of these VCR models
are used, connect via these terminals. See Series
Record Connection for details. Connect Series IN to
pin 3 and Series OUT to pin 4.
VEXT - Pin 6 outputs the following signal each time a
one-field image is recorded. You can combine this with
a video camera multiplexer which can be controlled
externally.
TAPE END OUT - Approx. 5V is applied to pin 5
when the tape reaches the end.
1-SHOT REC IN - You can connect this input (pin 9)
to ground (pin 7) to start a 1-shot recording.
