Timing 2x2 and 4x4 pixel binning are possible to enable previewing modes. Preview mode is

only available in Black and white otherwise the user has to use Overlay mode (but nei-

ther correction nor software LUT are applicable on displayed images).

Frame Timing Three timing modes are available: Continuous, external triggered and Integration Time

controlled (ITC).

The signals described in the following drawings are:

Notes: 1. Pixel is defined as valid (part of the Frame) when both LEN and FEN Signals are at

Low Level.

2. The latency (called Td after) of 1 Readout line Time defined below depends on the

binning mode. For no binning, this latency is around 104 µs.

3. Minimum Time at high level of LEN Signal is 10 µs (Transfer Time between two lines).

4. Minimum Time at high level of FEN Signal is 4 lines readout Time (around 416 µs).

5. Shutter Delay is adjustable via Commcam or RS232 commands (1, 5, 10 or 20 ms).
