SECTION 9

PELCO PROTOCOL MODE

9.1 Description

The Pelco Protocol Mode provides support for Pelco-P and

Pelco-D protocols, and is incorporated in AutoDome firmware

version 5.31 and higher. It features Auto Baud Detection which

automatically detects and adjusts the AutoDome protocol and

baud rate to match the controller’s.

9.2 Hardware Configuration

9.3 RS-485 Setup

To use the Pelco Protocol Mode, the AutoDome must be

configured for RS-485 operation.

1. Set the AutoDome configuration dipswitch #2 to ON.See

SECTION 1 and SECTION 2.

2. Connect the RS-422 controller Tx+ terminal to the

AutoDome’s RxD terminal.

3. Connect the controller’s Tx- terminal to the AutoDome’s

TxD terminal. See SECTION 1 and SECTION 2.

Both the Pelco controller and AutoDome must be configured

before connecting the devices together. The AutoDome will

respond to Bosch OSRD, Pelco-D, and Pelco-P commands.

The Pelco Mode only supports RS-485 protocol. It

will not transmit reponses to commands it receives.

9.4 Set Addresses

• Addresses 0 to 9998 are available for Bosch OSRD

commands.

• An AutoDome with an address set to 0 will respond to

commands sent to any address.

• Pelco-P protocol must use addresses 1-to-32.

• Pelco-D protocol must use addresses 1-to-254.

An AutoDome that was previously configured with an

address above 32 (Pelco-P upper limit) or 254 (Pelco-D

upper limit) can be used without re-addressing the

unit. However, care must be taken that no two

addresses are repeated.

For example:

Pelco-P addresses above 32 are repeated in multiples of

32 (1, 33, 65, 97 are the same).

Pelco-D address above 254 are repeated in multiples of

254 (1, 255, 509, 763 are the same).

9.5 Software

AutoDome firmware 5.31 or higher must be installed for Pelco pro-

tocol mode to operate. Procedures for uploading a new AutoDome

firmware must be followed to successfully install an upgrade.

Only a Bosch VP-CFGSFT firmware upload tool (sold

seperately) can be used to install a firmware upgrade to

the AutoDome.

9.6 Commands

The Pelco Set-Preset command is used by AutoDome to set

Presets 1 through 99. Some Presets have special meaning and

override the normal preset function as follow:

[PRESET] button for 2 seconds.

2 minutes after power is applied and

then reverts to normal Preset

disable Limit Stops in the Setup Menu
