6.3.1. Continuous operation 

This mode is used for applications not requiring asynchronous external trigger, but should run in 
continuous operation.  

The shutter time can be selected in 8 steps 8 steps, 1/125 to 1/12,000 sec. Via RS232C in 9 steps 
1/60 (Off) to 1/120000. or programmable from 2H to 524H (Off). Binning or partial scan can be 
used, but not together. 
For settings refer to chapter “7. Configuring the camera.” 
Refer to timing charts for details. 
 
To use this mode: 
 

Set: Rear

 for 

Normal.

 For RS-232C select 

Continuous

 

trigger mode. 

 

SW1-1 through SW1-3 on rear or RS-232C for shutter speed. 

 Other 

functions. 

 
Input: 

If used, input Ext. HD and Ext. VD to pin 6/12 and 7/12. 

 

[

JP10 short for HD 75

 termination. JP8 short for VD 75

 termination.

]

 

 

Note: 

Selection of shutter speed longer than the frame time in binning and partial 
scanning will result in an exposure equal the frame time

 

In partial scan, the shutter can not be completely off. Exposure is frame time –2H.
