Exposure Mode, Readout Mode, Line Rate and
Exposure Time
Overview
You have a choice of operating in one of seven modes. The camera’s line rate
(synchronization) can be generated internally through the software command
AcquisitionLineRateAbs or set externally with an EXSYNC signal, depending on your
mode of operation.
To select how you want the camera’s line rate to be generated:
1. You must first set the camera mode using the DALSAExposureMode command.
2. Next, if using mode 2, 6, 7, or 8 use the commands AcquisitionLineRateAbs and/or
ExposureTimeAbs to set the line rate and exposure time.
1. Set the Exposure Mode
Sets the camera’s exposure mode allowing you to control your sync, exposure time, and
line rate generation.
DALSAExposureMode = {Mode = 2, Mode3 = 3, Mode4 = 4, Mode5 = 5,
Mode6 = 6, Mode7 = 7 }
• Factory setting is mode 7.
