YSTEM DESCRIPTION
1.1 O
VERVIEW
The purpose of this document is to give an overview of the test system which for the 2/4Mpxl machine vision image
sensors produced by CMOSIS. This test system can be used for testing and verifying the operation of the
CMV2000/4000 image sensor.

The block diagram above displays the different parts of the CMV2000/4000 test system. The three upper blocks are
implemented on one PCB.
The fourth block is a standard third party frame grabber card which plugs into a PC’s PCI Express bus (NI 1433). For this
frame grabber and the PCB dedicated software has been developed in a LabVIEW environment.

ASING
The board is placed in a black metal box with the banana plug power cords, the CameraLink connectors and a tripod
holder coming out at the side.

ENS HOLDER
The CMV2000/4000 PCB is equipped with a C-mount lens holder. On this lens holder, off-the-shelf C-mount lenses can
be fitted. The image sensor requires 2/3 (CMV2000) or 1 inch (CMV4000) or bigger C-mount lenses.

POWER AND BIASING
This part of the test board includes the sensor, its power sources and biasing (decoupling to ground). The sensor is
easily removable from the test board because of the ZIF (zero insertion force) socket. If you want the replace the
sensor, simply lift the metal handle upwards 90°; this will open the socket. Remove the sensor and place another back
in the correct pins. No force is needed to place the sensor in the socket. Now close the socket by pushing the handle
down until it ‘clicks’. The sensor is now tightened and cannot fall out. The sensor should be placed according to the
picture below:
