Fig. 4. Camera Link connector

The digital output signals follow the Camera Link standardized multiplexed signal output interface. The output driver is NS type DS90CR283, and the receiver is NS type DS90CR284.

The following signals are found on the Digital Output Connector:

SerTC	RXD serial data to camera
SerTFG	TXD serial data to frame grabber
CC1	Trigger signal in for exposure control.
CC2	Trigger input for multiple exposure
X0 to X3	Camera Link multiplexed data out
Xclk	Camera Link clock. Used as pixel clock.

In the Channel Link X0 to X3 multiplexed signals the following signals are encoded.

D0 – D9	10 bit video data out
LEN	Line ENable. A pulse for the beginning of a new line.
FEN	Frame ENable. Video frame data is valid.
DVAL	Data VALid.
EEN	Exposure Enable.

The polarity for LEN, FEN and Multi is positive and TRIG in negative as factory setting. It can be changed by internal SW301-2 and 3 or RS 232C command FP and TP.
