5 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: –6 dBm, 47 kOhm).
Audio Out: Provides an audio output for a monitor or another
recorder (–9 dBm, 1.5 kOhm, unbalanced).
5.3 Using the 12-pin Terminals (Fig 4, Item 4)
Attach the wires of the alarm switch, door sensor or warning lamp
to the 12-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 9.
ALARM OUT - Approx. 5V is applied to pin 3 during an alarm
recording. This can be used to trigger an external device (i.e.
alarm bell).
SERIES - When two or more of this VCR model are used,
connect via these terminals. See Series Record Connection for
details. Connect Series IN to pin 5 and Series OUT to pin 6.
VEXT - Pin 8 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 10 when the
tape reaches the end.
1-SHOT REC IN - You can connect this input (pin 11) to
ground (pin 12) to start a 1-shot recording.
