iDR-switch User Guide AP5141

The iDR-switch is an add-on control expander for the iDR-8 audio mix processor. It provides an additional 24 switch
closure control inputs and 16 logic control outputs in a 1U high rack or desk mount case. Up to three units can be
connected providing up to 72 additional switch and 48 additional logic controls. These can be custom wired by the
installer to allow external equipment to control pre-determined mixer functions, or the mixer to control external
equipment. Typical applications include room wall plates for local volume control and source selection, patch recall,
logic control, automatic control of room dividers, projection screens, media players, lamps and other equipment.

The inputs and outputs are opto-isolated to avoid problems with equipment interaction. Grounding the switch inputs
using simple contact closures triggers the programmed function. The logic outputs are open collector and can be
wired to use the internal reference voltage or an external power supply. These typically drive LED indicators, filament
bulbs, relays and circuit logic. Wiring the interface should be carried out by competent installation personnel. The
switch and output functions are easily programmed using the iDR System Manager software.

The iDR-8 communicates with the iDR-switch via the DR-Link port. This uses the proprietary Allen & Heath DR-Link
protocol. A standard 2 metre CAT5 STP cable is provided. However, you can use a cable up to 300 metres long
letting you position the unit closer to the local switch wiring. A pass through connection lets you network up to three
units by daisy chaining them.

Plan the system

Before starting make sure you have planned how the

system is to work. Allocate the switch inputs and logic outputs and keep a log
of their intended function. Use the iDR System Manager software to configure
the system. Simulation windows are provided for you to try out your settings
without access to the units themselves. Refer to the Help file that comes with
the iDR System Manager software for details on how to assign the switch
inputs and logic outputs.

This product complies with the European Electromagnetic
Compatibility directives 89/336/EEC & 92/31/EEC and the
European Low Voltage Directives 73/23/EEC & 93/68/EEC.

NOTE: Do not remove the cover of the iDR-switch unit. There are no user
serviceable parts inside. Any changes or modifications to the equipment not
approved by Allen & Heath could void the compliance of the equipment and
therefore the users authority to operate it.
