The VG4 AutoDome supports three alternative control protocols that allows a user to send 

commands and to receive information from the AutoDome. The VG4 AutoDome supports the 

following protocols:

–

Pelco-P

–

Pelco-D

–

American Dynamics Manchester

–

Sensormatic RS-422

The VG4 AutoDome natively supports the two Pelco protocols. To use the American Dynamics 

Manchester or the Sensormatic RS-422 protocol you must purchase a separate module. The 

module contains instructions to install any additional hardware and information about 

additional on-screen menus.

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.

The AutoDome is configured from the factory for RS-485 operation in Pelco Protocol Mode.

1.

Connect the controller's TX terminals to the AutoDome's TxD terminals. See the 

AutoDome Modular Camera System Installation Manual for complete wiring instructions.

2.

Pan or tilt the keyboard joystick to confirm that control has been established to the 

AutoDome (approximately five (5) seconds).

RS-232/RS-485 Selection Switch

NOTICE! The AutoDome supports only the RS-485 protocol while in Pelco mode. It does not 

transmit responses back to the controller.

NOTICE! If control is not established, ensure that the RS-232/RS-485 selector switch is 

positioned to RS-485 (outward toward the LED lights). This switch is located on the bottom of 

the AutoDome CPU board, under the camera head and next to the LED lights. See Figure 4.1.
