Communications Protocol<br />

B1 Protocol Overview<br />

This protocol defines the method used to control the camera via a serial interface. The<br />

communication protocol defines the command format used and error messages provided.<br />

Note: As per customer needs, additional commands and functionality will continue to be<br />

implemented. Backward compatibility is planned for future cameras.<br />

B3 Command Format<br />

When entering commands, remember that:<br />

• Carriage return (CR) ends each command. The linefeed character is ignored.<br />

• Values in square brackets are optional.<br />

• The camera will answer each command with either "OK >" or "Error x: Error Message<br />

B4 Networking Mode<br />

The camera's network feature provides the capability to connect and control multiple<br />

cameras over a multi-drop RS485 link.<br />

The network feature consists of three commands and a set of definitions describing the<br />

behavior of the camera when the commands are sent in network mode.<br />
