6.4 Serial Communication
The Camera Link interface provides two LVDS signal pairs for the communication between the
camera and the frame grabber. This is an asynchronous serial communication based on RS-232
protocol.
The configuration of the serial line is:
• Full duplex/without handshaking
• 8-bit data, no parity bit, 1 stop bit
• 9600 bauds at power up, then programmable up to 115200 bauds (see register
Communication Speed Multiplieur @ 001H, Internal Register Mapping on page 16.
