Communication
Two LVDS pairs have been allocated for asynchronous serial commun
the camera and frame grabber. Cameras and frame grabbers should s
baud. These signals are
• SerTFG—Differential pair with serial communications to t
ication to and from
upport at least 9600
he 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
