Camera Link Implementation
1.2 Camera Link Input Signals
The input signals that the camera can accept via the Camera Link interface include a Serial to
Camera signal and an External Frame Start Trigger signal as described below.
1.2.1
Serial to Camera
The Serial To Camera (SerTC) input signal is an RS-644 LVDS signal as specified in the Camera
Link standard. The signal is input to the camera on pins 7 and 20 of MDR connector one as specified
in the standard and as shown in Figure 1 on
communication via a serial port integrated into the frame grabber as specified in the Camera Link
standard.
The RS-644 serial connection in the Camera Link interface is used to issue commands to the
camera that change parameter values. The serial link can also be used to query the camera about
its current setup.
1.2.2
External Acquisition Start Trigger (ExASTrig)
The camera can be set to accept an External Acquisition Start Trigger (ExASTrig) input signal,
which is used as an enabler for the frame start trigger. When the camera receives a proper
ExASTrig signal, its acquisition status will change from "waiting for acquisition start trigger" to
"waiting for frame start trigger". For details about using an acquisition start trigger with aviator
cameras, refer to the aviator User's Manual (AW000830xx000).
When the ExASTrig signal is applied to the camera via the Camera Link interface, it must be an
LVDS signal as specified for RS-644. The camera can be programmed to accept an ExASTrig
signal on the CC1, CC2, or CC4 inputs in the Camera Link interface.
Note that ExASTrig is edge sensitive and therefore must toggle. The minimum high time for the
ExASTrig signal is 1 µs and the minimum low time is also 1 µs.
1.2.3
External Frame Start Trigger (ExFSTrig)
The camera can be set to accept an External Frame Start Trigger (ExFSTrig) input signal to control
exposure and readout of the camera's sensor. When the ExFSTrig signal is applied to the camera
via the Camera Link interface, it is an LVDS signal as specified for RS-644. By default, the camera
will accept an ExFSTrig signal on the CC1 input in the Camera Link interface (pins 9 and 22 of the
MDR connector) as specified in the Camera Link standard. The camera can also be programmed
to accept the ExFSTrig signal on CC2 or CC4.
