camera (the camera will output video as soon as power is applied over the USB interface).
6. CAMERA CONTROLS
The NOCTURN XL is controlled by a serial communication protocol that can be addressed either over
the USB or the Camera Link ® compatible link.
BASIC COMMUNICATION SETTINGS
The serial communication should be set with the following configuration:
Number of bits: 8
Baud rate: 115200 bps
Parity: none
Number of stop bits: 1 bit
Flow control: none.
NOTE
The user can change the default baud rate to value other
than 115200bps by using the “baudrate” command
followed by a “save flash” command.
PROTOCOL
The protocol to communicate the NOCTURN XL console is based on ASCII printable messages. A
carriage return must be sent following a command. A “>” will appear at the console when the camera is
ready to accept messages. The camera will answer “OK” to all user command that are accepted and
“Error: <error message>” when an error occurs.
A standard message to the camera should have the following architecture: Command <Optional
Payload> <CR>.
