• In
ExSync
,
programmable
mode, the rising edge of ExSync triggers exposure and charge
accumulation for a pre-programmed period of time.
The actual start of exposure is 0.385 µs later than the rise of the ExSync signal. The line is
read out and transferred at the end of the pre-programmed period. The falling edge of
ExSync is irrelevant (see Figure 3-5).
A parameter called “Timer 1” is used to set the length of the pre-programmed exposure period.
Figure 3-5: ExSync, Programmable Mode
You can set the camera to operate in one of the ExSync controlled exposure modes using either
the Camera Configuration Tool Plus (see Section
) or binary commands (see Section
With the Camera Configuration Tool Plus, you use the Exposure Time Control Mode setting in the
Exposure parameter group to set the camera for ExSync operation and to select the edge-
controlled, 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 edge-controlled, ExSync level-controlled or ExSync programmable mode (see Section
). If you choose the programmable mode, you must also use the Timer 1 command to set
the exposure time.
3.2.1.1 Recommendations for ExSync Controlled Operation
When using ExSync controlled operation, several general guidelines must be followed:
• ExSync is edge sensitive and therefore must toggle.
• The minimum ExSync period is 1/Maximum line rate.
(Depending on whether spatial correction is used, this period is either 125 µs (with spatial
correction enabled) or 108.7 µs (with spatial correction not enabled)).
• The ExSync signal must remain high for at least 0.35 µs.
• There must be a minimum of 0.1 µs between the end of line transfer and readout of the next
line (see Figure 2-4 and Figure 2-5).
• The minimum exposure time is 1 µs.
