• In ExSync, programmable mode, the rising edge of ExSync triggers exposure and charge
accumulation for a pre-programmed period of time. The frame is read out and transferred at
the end of the pre-programmed period. The falling edge of ExSync is not relevant (see Figure
3-6).
A parameter called the "Timer 1" is used to set the length of the pre-programmed exposure
period.

Figure 3-6: ExSync, Programmable Mode
If you want to operate the camera at maximum exposure time and maximum frame rate, see
section 3.5 for further setting recommendations.
You can set the camera to operate in one of the ExSync controlled exposure modes using either
the Camera Configuration Tool Plus (see section 4.1) or binary commands (see section 4.2).
With the Camera Configuration Tool Plus, you use the Exposure Time Control Mode command to
set the camera for ExSync operation and to select the level controlled or programmable exposure
time control mode. If you select the programmable mode, you must also enter an exposure time.
When you enter an exposure time, the configuration tool will automatically set the "Timer 1"
parameter to the correct value.
With binary commands, you must use the Exposure Time Control Mode command to select
ExSync level-controlled or ExSync programmable mode. If you choose the programmable mode,
you must also use the Timer 1 command to set the exposure time.
