CV-M4+/M4+CL, CV-M7+/M7+CL

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	Frame enable
LEN	Line enable
PCLK	Pixel clock
DVAL
EEN	Exposure enable. (Low during active exposure).

See the full connector pin assignment for LVDS a Camera Link in chapter 5.2 and 5.3.
