2.4 Input Signals
The only control signal that can be input into the A102
is an RS-644 LVDS signal as specified in the Camera Link standard. Section 2.4.1 describes the
function of the ExSync signal.
2.4.1 ExSync: Controls Frame Readout and Exposure Time
The ExSync input signal is used to control exposure time and frame read out. When the camera
is operating with an ExSync signal, two exposure time control modes are available:
level-controlled and programmable. (see Section 3.2)
ExSync can be a periodic or non-periodic function.
The frequency of the ExSync signal determines the camera's frame rate:
Note that ExSync is edge sensitive and therefore must toggle.
Minimum high time for the ExSync signal depends on whether ExSync Level-controlled or ExSync
Programmable mode is used (see Sections 3.2.1.2 or 3.2.1.3, respectively)
The ExSync signal is typically supplied to the camera by a frame grabber board. You should refer
to the manual supplied with your frame grabber to determine how to set up the ExSync signal that
is being supplied to the camera.
