Serial Protocol and Command Format
The Camera Link interface provides two LVDS signal pairs for communication between the camera and
the frame grabber. This is an asynchronous serial communication based on RS-232 protocol.
The serial line configuration is:
• Full duplex/without handshaking
• 9600 bauds (default), 8-bit data, no parity bit, 1 stop bit. The baud rate can be set up to 230,400
6.2.1
Syntax
Internal camera configurations are activated by write or readout commands.
The command syntax for write operation is:
w <command_name> <command_parameters><CR>
The command syntax for readout operation is:
r <command_name><CR>
6.2.2
Command Processing
Each command received by the camera is processed:
•
The setting is implemented (if valid)
•
The camera returns “>”<return code><CR>
We recommend to wait for the camera return code before sending a new command.
Table 5-1.
Camera Returned Code
Returned code
meaning
>0
(or “>OK”) : All right, the command will be implemented
>3
Error bad CRC in command
>16
Command Error (Command not recognize or doesn't exist)
>21
Invalid Command ID (the Command doesn't exist).
>33
Invalid Access (the receipt of the last command has failed).
>34
Parameter out of range (the parameter of the last command send is out of range).
>35
Access Failure (bad communication between two internal devices).
