The Pelco Mode features Auto Baud Detection that automatically detects and adjusts the
AutoDome protocol and baud rate to match that of the controller. The AutoDome responds to
Pelco-D or Pelco-P protocol commands.
4.1 Hardware Configuration
The AutoDome is configured from the factory for RS-485 operation in Pelco Protocol Mode.

AutoDome Modular Camera System Installation Manual for complete wiring instructions.
