Control Link

DHD Series 52 Control Link (52-8589) allows you to remote control one controller connected to a remote core using another controller connected to your studio core. Both cores have to be connected via IP network. When using Control Link, the control data that are usually transmitted via APC connections, will be forwarded inside the core to the built-in DHD Network ethernet interface (See schematic image below).

Control Link functional principle (schematic)

Configure a user defined key to trigger a control link connection. The core will connect and mirror with the remote module.

Important

Requirements:
52/XC2, 52/XD2, 52/XS2 Core device and 52-8589 License on both sides per controller connection.
52/XS2 Cores additionally require 52-1950 license.

Use Cases

Multiple Commentary Speakers

Example 1: Multiple Commentary Speakers

One engineer uses only one 52/TX to control 12 commentator desks. These desks are running as 4 virtual mixers in 3 DSP core devices and are fully virtualized.

OB Van

Example 2: OB Van

The staff onsite with the OB van can remote control the main studio console using physical hardware in the OB van.

Configuration

Make sure you have Use 52-8589 Control Link checked on <device> page. You need to have a valid license on your core device in order to send the configuration to it.

In the project tree, go to <device>/Logic/Control Links.

Note
<device>/Logic/Control Links - page is only visible, if Use 52-8589 Control Link is selected at the <device> page.

Toolbox8 Control Links page

Click Add in the Control Links area to add a new control link. Select the newly created control link.

In the Edit Control Link section:

Then you can add a control link condition. Conditions will connect your local module with the designated remote module, when they become true. Click Add to add a new condition.

Conditions will always be prioritised from top to bottom.

Important
Control link has no connection timeout! If a connection via network is not possible and you have no chance to disable the control link trigger logic, you will need to reset the core or re-send config to regain access to your module.
