10.5.2 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. 35 through fig. 44.

To use this mode:
Set function:

Trigger mode

Edge Pre-select (EPS)

Readout mode

Sync, async,

Output Select

8-bit, 10-bit, 12-bit

Scanning

Full/Partial

Vertical binning

ON/OFF

Shutter

Programmable, Exposure Time Abs

Programmable Shutter

0.5 to 792 L (1L unit)

Accumulation(Auto)

LVAL sync/LVAL async

Other functions

Input:

External Trigger

GigE I/F, Hirose 12-pin,Hirose 6-pin

Important Note:
1 The minimum duration of the trigger is 2L. The minimum period of trigger is as follows.

Sync mode:
Sync

Smearless OFF

FVAL(792L) + 3L + (Difference shutter time between
BW1 and BW2)

Smearless ON

Smearless Time(198L)+1+ ( longer exposure time
between BW1 and BW2) + FVAL(792L) + 3L

Sync mode:
Async

Smearless OFF

FVAL(792L) + 3L

Smearless ON

Smearless Time(198L)+1+FVAL(792L)+3L

FVAL(792L) is the FVAL period of continuous operation.

2 In case that “Readout mode” is set to “SYNC”, the trigger input for BW1 is used for both

channels. The exposure time can be set individually, but the output timing is
synchronized with the rising edge of the longest exposure time.
