Appendix A: Camera Link™ Reference, Timing, and Configuration Table 77
A.5 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 programming 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
www.dalsa.com Web site.
