The pins on the camera connector should be cleaned and dried then sprayed with a
silicone-based lubricant. Grease should not be used on enclosed connectors such as the
standard LPMBH series. Grease will eventually become impacted in the mating connector,
forcing the contacts apart and causing intermittent operation.
3.3 CAMERA BOOT-UP SEQUENCE
When the camera is energized, the video signal consists of a blue screen for 5 to 7
seconds. Then the video as seen by the camera is displayed.
NOTE:
While the camera is booting up, all RS-485 commands will be ignored. Only
after video is displayed on the screen will RS-485 commands be accepted.
3.4 EXPOSURE CONTROL
The RS-485 CEX-HD Camera provides operation over a wide range of scene illuminations.
For most operations, it is recommended to simply leave the camera in automatic exposure
mode, as it generally does very well at optimizing itself for the ambient illumination
conditions.
In the event that manual Exposure Control is desired due to unusual viewing conditions
such as severe reflections or flashing lights, the IC-LINK must send a manual Exposure
command followed by direct Iris position commands. The operator normally adjusts the
joystick slider to send a direct Iris position command until an optimum display is seen on
the television monitor.
To restore automatic Exposure Control: the IC-LINK must send EXP AUTO command.
3.5 ZOOM CONTROL
The zoom lens operates whenever the IC-LINK sends direct Zoom position commands.
The zoom function continues until the Zoom position reaches its commanded position or
the lens zoom limit is reached. The zoom position is relative to the position of the joystick
slider, moving the slider forward corresponds to Tele and moving the slider backwards
corresponds to Wide. Tele operates towards increasing focal length settings providing
reduced viewing angles with increased magnification of objects in the scene. Wide
operation reduces focal length settings increasing viewing angles and allows viewing of
greater areas of a scene.
When zooming towards the tele end from the full wide end, the optical zoom is activated
until the optical zoom limit is reached.
