cameras have overvoltage protection. If an input voltage greater than 14.5 VDC is applied
to the camera, the camera will automatically switch off the internal power applied to the CCD
sensor so that the sensor will be protected. In this situation, you will still be able to communicate
with the camera and the camera will still be able to transmit test images, however, no live images
can be generated.
Although overvoltage protection is present, we strongly recommend that you avoid applying an
input voltage greater than 13.2 VDC
You can check to see if the camera has detected an overvoltage condition with the Camera
Configuration Tool Plus (CCT+) or by using binary read commands from within your own
application to read the camera’s inquiry registers.
With the CCT+
With the CCT+ (see Section 4.1 ), you use the Voltage Error parameter in the Camera Information
parameters group to determine if an overvoltage condition has been detected. If the value is 1, an
overvoltage condition has been detected.
By Reading Inquiry Registers
You check for an overvoltage condition by reading the value of bit 6 in the Camera Status field of
the Camera Status Inquiry Register (see page
4-9 ). If the bit is set to 1, an overvoltage condition
has been detected.
See Section 4.2.1 for an explanation of Inquiry Registers and Section 4.3.1 for an explanation of
using read/write commands.
Caution!
Be sure that all power to your system is switched off before you make or break
connections to the camera. Making or breaking connections when power is on
can result in damage to the camera.
The camera is not protected for reverse voltage. If reverse voltage is applied
to the camera while it is connected to a frame grabber in a PC, the camera
could be seriously damaged.
L
The Voltage Error parameter in the CCT+ and bit 6 in the Camera Status field of the
Camera Status Inquiry Register will be set to 1 if the camera detects an overvoltage
situation. They will remain set to 1 until the condition is corrected and a camera re-
set or a power off/on has been performed.
