Restart Continuous Trigger mode. RCT.  
The RCT mode makes it possible to use a lens with video controlled iris for intelligent traffic 
surveillance applications, ITS. The camera is running continuously, and the iris is controlled from 
the iris video output. When a trigger pulse is applied, the scanning is reset, the previous signal is 
dumped with a fast dump read out, and the new triggered exposure is started. This fast dump 
read out takes 133 H (5,23 msec. and it has the same effect as “smearless read out”. Smear over 
highlighted areas are reduced for the triggered frame. In edge pre-select mode (TR=1), the RCT 
mode (RC=1) can be activated. RCT cannot be selected by switch settings.

All trigger modes can be H synchronous or H a-synchronous. (HC=0, HC=1)  
In Edge Pre-select mode (TR=1), the Restart Continuous Trigger mode can be activated 
(RC=1) by RS-232C and CL only. 
 
6.2. Output of Timing Signals  
It is not possible to synchronize the camera from an external sync source except by extern 
trigger. The camera will always run with its internal X-tal controlled timing.  
 
The CV-M4
+
 camera is designed for easy interfacing to frame grabbers with LVDS signal levels 
(EIA64), or with Camera Link interface. 
To synchronize the video data transfer from the camera the following signals are available: 
 FEN

 LEN

 PCLK

 DVAL

Exposure enable. (Low during active exposure). 
See the full connector pin assignment for LVDS a Camera Link in chapter 5.2 and 5.3.
