4 – Message Format Specification

The CommandHub can be used for two types of control. It can be used to send device-specific control commands to

Attero Tech unIFY devices on the Dante network. It can also be used to send network routing and more general control

and monitoring commands.

4.1 – Device Control

Control of unIFY devices is achieved by sending UDP messages to the UDP listen port (by default, port 3000) of the

CommandHub on the control network side. These commands are converted and then passed on to the device via the

CommandHub's Dante interface using a Dante proprietary protocol. Any responses from the device are delivered back

to the CommandHub which in turn, sends them to the UDP Response port at the source IP address of the original command

message.

*Note: Any unIFY device being used with a Command Hub **MUST** be setup to use the Dante proprietary interface. For

new devices to be used with a CommandHub, the order number should include a "–C" suffix. For existing devices, they

must be product version V1.x or be identified using unIFY Control Panel of having Direct UDP set to "No".

Each device uses the same message structure but has a unique command set based on the devices own features. The

commands a particular device supports can be found in the unIFY 3

area of the registered users section of the website (use the "Log-in" button on the Attero Tech website).

As these commands are being processed by the CommandHub, the CommandHub will need to know which device the

command is intended for. As a result, messages send to the CommandHub for device control must have the devices

name and a space prefixed to the actual control command. For example, a message to the CommandHub for an unD3IO

would look like this:

unD3IO-000000 IG 1 0.0dB<CR>

This command sets the input 1 to line level for device unD3IO-00000.

*NOTE: The devices name is case sensitive and must match exactly the device name as shown in Dante Controller. Any

inaccuracies in the case for characters contained within the name will give indeterminate results.
