6.3.2 Edge Pre-select (EPS) Trigger Mode
An external trigger pulse initiates the capture, and the exposure time (accumulation time) is
the fixed shutter speed set by registers. The accumulation can be LVAL synchronous or LVAL
asynchronous. The resulting video signal will start to be read out after the selected shutter
time.
For timing details, refer to fig. 20 through fig. 27.
To use this mode:
Set function:
Trigger mode EPS
Scanning
Full, Partial
Vertical binning ON / OFF (CM-141MCL only)
Shutter mode Preset, Programmable, Fine Exposure
Shutter speed 1/60 to 1/10,000
Programmable exposure 2 L to 1052 L
Accumulation (Auto) LVAL Sync / LVAL a-sync
Other functions and settings
Input:
External trigger 12-pin Hirose or Camera Link

In the case of asynchronous mode, the exposure time should be added to the above
table.
