2. CONNECTIONS AND OPERATIONS
------ Notes on connecting ----------------------------------------------------------------------------------------------------- -
• Power plugs of connected equipment must be disconnected before installations.
• A 75-ohm coaxial cable (3C-2V or 5C-2V) is required for standard connection.
• For details of wiring and operation of equipment to be connected, refer to their operation manuals.
• Lenses, coaxial cables for video signals and the power cord are not supplied with the camera.
1. Basic connection
Single system configuration
MONITOR TV
24V AC
AC 120V
OPOWER CORD
(twisted pair line)
(*)Power cord: minimum wire size
of 18 AWG is recommended.
24V AC UL Listed Class 2 power supply
Do not overload power supply —
Since this camera uses 24V AC UL Listed
Class 2 power supply, it should be connected to
a power supply that allows for at least 5w
consumption.
Line - Lock control
Matching the vertical synchronization with the power frequency is called the Line-Lock.
When two or more cameras are switched by the video switcher for viewing by a monitor TV, the vertical
sync, phase can be locked with the power frequency, and a stable vertical sync, is obtained without
being disturbed at the time of switching.
MONITOR TV
Cautions:
• The camera is synchronized to the power frequency of 60 ± 1 Hz covering a normal fluctuation of the
power frequency. However, the camera may not cover a large fluctuation caused from the power
generated by an engine generator, etc.
• It takes about 10 seconds or more until a stable synchronization is obtained after the power is turned
on. This is normal, because several seconds are required to stabiiize the camera against power
noise.
• Refer to " 7.LINE-LOCK PHASE “ for adjustment.
2. Operation
(1) Mount a lens on the camera and connect equipment. Applicable lenses are specified in Section 3
" LENS ".
(2) Adjust the lens diaphragm and focus for optimum image.
