Operation Modes
This camera can operate in 3 primary modes.
1.
TR=0
Continuous Mode.
Pre-selected exposure.
2.
TR=1
Pre-select Mode.
Pre-selected exposure.
3.
TR=2
Pulse Width Mode.
Pulse width controlled exposure.
6.4.1.
Continuous operation
For applications not requiring asynchronous external trigger, but should run in continuous
operation, this mode is used.
For timing details, refer to fig. 14 through fig. 19.
To use this mode:
Set function:
Trigger mode to “Continuous”.
TR=0
Scanning
SC=0 through 5
Programmable Partial
PRGP=1
V Binning
VB=0 or 1
Shutter mode pre-set or programmable
SM=0 or 1
Shutter speed or
SH=0 to 10
Programmable exposure
PE=2 to 2072
Auto shutter
ASC=0 or 1
Other functions and settings
6.4.2.
Pre-select Trigger Mode
An external trigger pulse initiates the capture, and the exposure time (accumulation time) is
defined by the SH or PE commands.
The resulting video signal will start to be read out after the selected shutter time.
For timing details, refer to fig. 14 through fig. 19 and fig. 20 & 21.
To use this mode:
Set function:
Trigger mode to “Edge pre-select”.
TR=1
Scanning
SC=0 to 5
Programmable Partial
PRGP=0 or 1
V Binning
VB=0 or 1
Shutter mode to pre-set or programmable
SM=0 or 1
Shutter speed or
SH=0 to 10
Programmable exposure
PE=2 to 2072
Auto shutter
ASC=0 or 1
Other functions and settings
Input:
Ext. trigger. Camera Link or 12-pin Hirose
TI=0, TI=1
Important notes on using this mode
1.
The minimum trigger duration >2 LVAL.
2.
Depending on the timing of the leading edge of the trigger pulse in relationship to FVAL,
accumulation will be synchronous or a-synchronous in relationship to LVAL. See chapter
6.1.6. for details.
3.
The minimum interval of the trigger is as follows (in case of LVAL sync). In LVAL async
mode, the exposure period should be added.
