2.4 Input Signals
An external sync (ExSync) signal is the only control signal that can be input into an L304kc
camera.
2.4.1 ExSync: Controls Line Readout and Exposure Time
The ExSync input signal can be used to control exposure time and line read out. 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 3.3.
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.
