Communication
Two LVDS pairs have been allocated for asynchronous serial communication to and from
the camera and frame grabber. Cameras and frame grabbers should support at least 9600
baud. These signals are
• SerTFG—Differential pair with serial communications to the frame grabber.
• SerTC—Differential pair with serial communications to the camera.
The serial interface will have the following characteristics: one start bit, one stop bit, no
parity, and no handshaking. It is recommended that frame grabber manufacturers supply
both a user interface and a software application programmming interface (API) for using
the asynchronous serial communication port. The user interface will consist of a terminal
program with minimal capabilities of sending and receiving a character string and
sending a file of bytes. The software API will provide functions to enumerate boards and
send or receive a character string. See Appendix B in the Official Camera Link
specification on the Web site (http://www.dalsa.com/mv/knowledge/appnotes.aspx).
Power
Power will not be provided on the Camera Link connector. The camera will receive
power through a separate cable. Camera manufacturers will define their own power
connector, current, and voltage requirements.

IMPORTANT:
This camera uses the
falling
edge of EXSYNC
FRAME VALID
to trigger line readout,
unlike previous DALSA
cameras, which used the
LINE VALID
rising edge.
