Features

The name of Coaxitron derives from the fact that is specifically written to operate over coaxial cable. The protocol was created to send Pan, Tilt and Zoom, or PTZ, commands to a Pelco security camera.

Function

Command messages are fed over the same line as the video feed. This means that is not necessary to run separate cables for data. Pelco has other protocols for newer cameras. These are called the P and D Protocols. P and D commands can be fed over a Coaxitron connection via a Coaxitron Translator -- another device produced by Pelco.

Format

Coaxitron sends messages to devices in the form of a 4-byte code. The bits in these bytes each represent a command to control the camera. If the bit of a command is set, the camera must perform the action corresponding to that bit.
