JAI M4+ CL Manuale Utente

 

- 16 - 

 

 

The trigger leading edge will start the exposure H synchronous or H a-synchronous (HC=0, HC=1).  
The exposure stops and is read out after the shutter time selected. It can be the 10 steps in 
normal or 1056 steps in programmable. SM=0 or SM=1. This mode will operate with full and 
partial scanning and with V-binning (M4

+

 and M4CL

+

 only). Partial scanning and binning in 

combinations is not allowed. 
In this mode the Restart Continuous Trigger mode (RC=1) can be activated. (By RS-232C and CL  
only). The camera is then running continuously, and it can be reset and restarted by the trigger 
pulse. 
If smearless read out (SL=1) is used, the exposure starts with a delay 133H (5.23 msec.) after the 
trigger. An EEN pulse will indicate the active accumulation time, and a FEN pulse indicates that 
the resulting video is read out. 
 

To use this mode:  
Set function: 

Trigger mode “Edge Pre-select”  

TR = 1 

 

Shutter mode “Normal” or “Programmable” 

SM=0, SM=1 

 

 

“Shutter Speed” 

SH=0 through 9 

 

“Programmable exposure” 

PE=0 through 1057 

 

“H synchronous trigger” 

HC=0, HC=1  

 

“Restart Continuous Trigger” 

RC=0, RC=1 

 “Smearless 

readout” 

SL=0, 

SL=1 

 

 

Polarity and other functions 

Input: 

Ext. trigger to LVDS/Camera Link or pin 10 on 12-pin connector.  

 

 

Important notes on using this mode.

 

•  The duration of the trigger should be >2H to <3V. (>72.64µsec to <120msec). 
•  The minimum trigger interval should be >(exposure time + 1 frame). A new trigger must 

not be applied during the previous frame read out. (Before FEN is high).  

•  Smearless readout cannot be used together with Reset Continuous Trigger.
