X Series DSP Cameras
Installation Instructions
CAUTIONS
In order to avoid damaging your camera, note the following points.
1) The camera has threaded mounting points on the top and bottom of the case.
Only use a standard, photographic mounting bolt with a 1/4-20 UNC thread.
2) Before fitting the lens, make sure that its back will not touch the CCD sensor or
associated components when screwed fully home.
3) Do not touch the image surface of the sensor. If the sensor is accidentally
touched, only clean it using isopropanol.
4) Do not expose the sensor to direct sunlight as this may impair the performance
of the camera.
POWER SUPPLY
Baxall X series cameras are available in AC mains and AC and DC low voltage types.
The
voltage required to operate the camera is clearly marked on the rear panel of the
camera
. The green POWER LED on the rear panel indicates that power is connected.
Only
power low voltage cameras from a class 2 isolated power supply
. The power
consumption of a Baxall X series camera is less than 5 Watts.
Mains power supply
Cameras that are intended to operate directly from the mains supply are fitted with a non-
detachable power supply cord. The voltage of operation is clearly marked on the rear panel of
the camera. Generally this is 98 - 260V AC at 50Hz. REFER TO THE WIRING INSTRUCTION
LABEL ATTACHED TO THE SUPPLY CORD and terminate the cord with the appropriate mains
plug fitted with a 3A fuse.
MAINS CAMERAS MUST BE CONNECTED TO A PROTECTIVE
EARTH
. Ensure that a secure means of isolation from the mains is provided for the camera in
accordance with the national wiring regulations of the country of installation.
Auto-switching power supply
Cameras fitted with an automatic selecting power supply operate between 11-40V DC and
12-30V AC. Connections and polarity are indicated above the screw terminals on the rear
panel.
The power supply must be a class 2 isolated type
.
VIDEO CONNECTIONS
To obtain a video output, connect a video coaxial cable terminated with a 75
W
BNC connector
to the BNC socket marked VIDEO OUT on the rear of the camera.
On selected cameras, a means of external synchronisation may be provided - see the table on
page 2 for details. For external synchronisation, connect a video coaxial cable terminated with
a 75
W
BNC connector to the socket marked GENLOCK on the rear of the camera. The GENLOCK
facility synchronises to either a 1V peak-to-peak video signal or a standard sync plus blanking
signal. A signal connected to the GENLOCK input automatically overrides all other synchronisation
settings.
On colour cameras, the genlock facility locks the lines and not the subcarriers together.
