JAI CV-L105 Manuel D’Utilisation

 
Internal Trigger. Scan mode. 
The camera will operate continuously with 
its internal trigger.  

The exposure is equal to the scanning time 

set by the SCAN parameter via RS-232C only. 
SHUTTER parameter has no meaning here. 
SCAN value 150 µs through 32.5 ms. 
 
 
Internal Trigger. Shutter mode. 
The camera will operate continuously with  
its internal trigger.  

The scanning time is set by the SCAN 

parameter via RS-232C only.  
The exposure is set by the SHUTTER 
parameter via RS-232C only. 
SCAN value 150 µs through 32.5 ms. 
SHUTTER value 1 µs through 32.35 ms. 
 
 
External Trigger. Scan mode. 
For every EXT TRIG input the ongoing  
integration period is terminated and charge 

is read out. At the same time it starts a new 
cycle. 

The exposure time is therefore dependant of 
the line rate. 
SHUTTER and SCAN parameters has no 
meaning here. 
Trigger pulse width (high period) >4 clk. *) 
Trigger interval >2120 clk to ∞ 
 

 
External Trigger. Shutter mode. 
The exposure time is governed by the low  
period of the EXT TRIG signal. Exposure starts 
at the falling edge of the EXT TRIG signal and 
ends with the rising edge. The integration 
time is independent of the line rate. 

SHUTTER and SCAN parameters has no 

meaning here. 
Trigger pulse width (high period) >4 clk.  *) 
Exposure time (low period) >2102 clk to ∞ 
 
*)  1 clk is 33.3 ns for 30 MHz clock 
    1 clk is 66.6 ns for 15 MHz clock
