7 Configuring the camera using the serial interface.

7.1Mode Setting using ASCII commands via the RS-232C port.

The configuration of the CV-M77 camera can be done via the RS-232C port. The camera is to be set up via an ASCII terminal or from a PC running terminal emulator software.

Below is the description of the ASCII based short command protocol.

The RS-232C serial interface specification for CV-M77 is:
