RS-232 Serial Command Reference
The Vaddio RS-232 Serial Control Protocol is similar to the Sony
®
VISCA command set in order to be
compatible with several popular control devices. Not all VISCA commands are supported, and there are
Vaddio-specific commands in the following command and inquiry lists.
Be sure the camera is set to the same baud rate as the device originating the commands. For the
RoboSHOT 20 UHD, this is DIP switch 5 on the back of the camera. For the RoboSHOT 40 UHD, this is a
soft DIP switch available in the web interface on the System page (DIP Switches tab).
