8.3 STARTUP
After completing the mechanical and electrical connections to the A30 camera, you can begin
software configuration as follows:
1. Power on the camera. Wait for the camera startup. The system bootstrap requires a few
seconds to complete.
2. Start VPM. It will automatically search for any cameras on the network. Select the desired
camera from the list, then click Connect to Device. The PC will automatically connect to the
camera.
Upon connection, VPM is in Edit mode with all the tools necessary to create vision programs.
Refer to the Impact Reference Guide for more details.
8.3.1 Calibration
VPM provides calibration software to insure that the measurements indicated in VPM tools
accurately relate to the inspected object’s measurements. You may calibrate a camera using a
calibrated target, a part with known dimensions, or you can enter the camera’s units-per-pixel
factor manually.
Refer to the Calibration Panel section of the Impact Reference Guide for details.
Under-exposure:
To correct this result it is recommended to change the parameters in the following order:
1. increase the Exposure Time
2. increase the Gain
NOTE
In general, a longer exposure time corresponds to a lighter image but is
susceptible to blurring due to code movement. Exposure time is also limited
by the lighting. Longer exposure times can be set if the power strobe
level is lowered.
High gain settings may produce a grainy image that may affect the
inspection process.
