Connecting a Light Module
This section describes how to connect light modules to your Cognex frame grabber
Primary and Auxiliary Light Modules
Light ports are numbered the same as their associated camera port, from 0 to 3.
One Primary Per Camera
Your Cognex frame grabber supports one primary light module per camera port, for one
to four cameras. When using one light module per camera, connect the light module to
the light port numbered the same as the camera port. Thus, for example, connect a light
module to light port 2 to illuminate the scene under the camera attached to camera
port 2. The case of one primary light module per camera port is summarized in Table 5.
One Primary, One Auxiliary per Camera
Your Cognex software package may also support the use of two light modules each for
one or two camera ports. When there are two light modules per camera port, one light
module is primary and one auxiliary. Two light modules per camera can be used, for
example, to simultaneously illuminate the camera’s field of view from the top and from
the side.
If your Cognex software package supports primary and auxiliary light modules, the
primary light port is always the one with the same number as the camera port. For the
auxiliary light port, you can select any one of the other three light ports, as long as it is
not used for another camera’s primary light port. For example, if you connect a primary
light module for camera 0 to light port 0, you can connect an auxiliary light module to
any unused light port among 1, 2, or 3.
