6.4.5. Burst Trigger mode
With the burst trigger function, a single trigger pulse can start a sequence with five previous set
pre-selected programmable exposures. The five shutter times can be set with BSH1 through
BSH5. (Exposure 1H through 1216H.) The exposure is LVAL synchronous. Preset shutter (SM=0)
can not be used.
The sequence will start with the first exposure at the first LVAL pulse after the trigger leading
edge, and the result is read out after the selected shutter time. During the read out of the
previous frame, the next exposure starts. It will continue until exposure 5 is read out.
This mode will operate with full and partial scanning.
An EEN pulse will indicate the active accumulation time, and a FVAL pulse indicates that the
resulting video sequence is read out.
To use this mode:
Set function:
Trigger mode “Burst EPS”
TR=4
LVAL synchronous accumulation to “synch”
LS=0
Burst Shutter 1
BSH1=1 through 1216
Burst Shutter 2
BSH2=1 through 1216
Burst Shutter 3
BSH3=1 through 1216
Burst Shutter 4
BSH4=1 through 1216
Burst Shutter 5
BSH5=1 through 1216
Scanning format
SC=0 through SC=4

Input:
Ext. trigger to Camera Link or pin 10 on 12-pin connector.
Important notes on using this mode.
•
The duration of the trigger should be >2LVAL to <3FVAL.
•
Min. trigger interval is first ex 5 FVAL + 3 LVAL.
•
A new trigger must not be applied before FVAL is low after frame 5.
•
1LVAL = 47.9

For horizontal timing refer to 6.2.3 through 6.2.6. (Fig.16. through fig. 19.)
For LVAL sync/a-sync accumulation, refer to 6.2.7. (Fig. 20. through fig. 23.)
