38 Serial Interface: How to Control the Camera
Non-concurrent mode occurs when integration and readout are performed serially. In concurrent mode
integration and readout can overlap.
To set the exposure time, the camera must be operating in exposure mode 2, 6 or 10. If you enter an
exposure time outside of a valid range, the input will be clipped to the min or max.
If you enter an exposure time which overlaps with the frame readout, the exposure time will automatically
adjust to integral units of exposure time increments. The camera sends a warning when this occurs.
To select how you want the camera’s frame rate to be generated:
• You must first set the camera’s exposure mode.
• Next, depending on the specified exposure mode, set the frame rate and set the exposure time.
Exposure Mode Serial Command: sem
Purpose: Sets the camera’s exposure mode allowing you to control
your EXSYNC signal, exposure time, and frame rate
generation.
Syntax:
• sem m
Syntax Elements:
• m
Exposure mode to use. Factory setting is 2. Possible
values are 2, 4, 6, 9, 10. For more information, refer to
section
3.7.3 Exposure Modes in Detail.
Notes: To obtain the current value of the exposure mode, use the
command
gcp.

Purpose: Sets the camera’s exposure time in µs.
Syntax:
• set f
Syntax Elements:
• f
Floating point number in µs. Allowable range is 40-
4000000 µs.
Notes: Camera must be operating in exposure mode 2, 6 or 10.
To retrieve the current exposure time, use the command
