2.4 Input Signals

An external sync (ExSync) signal is the only control signal that can be input into an L400

2.4.1 ExSync: Controls Line Readout and Exposure Time

The ExSync input signal is used to control exposure time and line readout. The ExSync signal is
an RS-644 LVDS signal as specified in the Camera Link standard and is usually supplied to the
camera by the frame grabber. The signal is input to the camera on pins 9 and 22 of the 26-pin
MDR connector as specified in the Camera Link standard.
When the camera is operating with an ExSync signal, three exposure time control modes are
available: edge-controlled, level-controlled and programmable. For more detailed information on
the three modes, see Section 3.4.
The period of the ExSync signal determines the camera's line rate:
Note that ExSync is edge sensitive and therefore must toggle.
Minimum high time for the ExSync signal is 0.1 µs.
