Introduction

The DR-link adapter card needs to be fitted to the DR66 or DR128 if you wish to use the optional DR-switch
add-on unit, or any other add-on that requires the DR-link serial connection. The DR-switch 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, automatic control of room dividers, projection screens, media players, lamps and other
equipment.

The DR66/128 communicates with the DR-switch via an RJ45 serial connection running the Allen & Heath DR-
link protocol. This interface is not available on the standard DR66 and DR128. The adapter card needs to be
fitted to provide the additional serial port. This uses the SysNet slot. Refer to the important notes below.

The kit includes parts for fitting the card to either the DR66 or the DR128. Installation is a straightforward
process requiring removal of the DR66/128 top cover, fitting the option card provided and plugging on the cable
harness supplied. Please read these fitting instructions carefully before starting and heed the precautions noted
for trouble free installation and use.

Important Notes

To use the DR-switch the DR66/128 must be running DR
operating software version 2 from V2.11 or greater. DR-
switch will not function using earlier versions of software.
Make sure your PC is running the compatible version of
WinDR. Refer to the Help file provided with the software for
details on how to program the controls. These settings are
stored as part of the DR66/128 mixer patch memories.

The latest version of DR operating software can be
downloaded from the Allen & Heath web site:

The DR-link interface card fits into the SysNet option slot in
the DR66/128 mixer. This means that you cannot have DR-
link and SysNet installed at the same time. The SysNet
protocol can be run on the RS232 port instead if required.

NOTE: This work should be carried out by competent service personnel. 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. Whilst we believe the information in these instructions to be reliable we do not assume
responsibility for inaccuracies. We also reserve the right to make changes in the interest of further product
development.

DR-LINK Adapter Card Fitting Instructions AP4615 1

Fitting the DR-link Interface Card to the DR66/128

The kit includes the DR-link interface card, an IDC cable harness and brackets suitable to fit the card into either
the DR66 or the DR128 mixer. Follow the instructions below according to which mixer you have.

The interface card contains sensitive integrated circuits which can be damaged by static discharge from human
body contact. The card is packed in an anti-static conductive bag to protect it during shipment. To avoid
damaging the static sensitive components make sure you discharge any static electricity from your body and
any tools you use. One way to do this is to touch the grounded bare metal of the DR chassis. Handle the card
by its edges only.

Step 1

Turn off power to the DR66/128 and unplug the
mains cable. Remove the fixing screws as
shown and lift off the top cover. Do not remove
the power unit safety cover or its internal
shield.

Step 2

Remove the rear panel SysNet option slot
blanking plate by unscrewing the two fixing
screws.

Step 3

Locate and carefully unplug the 26way harness
that connects between the CPU and Connector
circuits.

Step 4 (DR66)

Assemble the DR66 metal bracket on to the
DR-link card using the two screws, washers
and nuts provided. Tighten the nuts to ensure
good contact with the PCB ground plane.
Press in the two plastic support pillars.

Step 4 (DR128)

Assemble the DR-link card on to the DR128
metal bracket using the four screws provided.

Step 5

Fit the assembly into the DR66/128 SysNet slot
using the two screws provided. Press the
DR66 plastic pillars into the Connector circuit.
Ensure the screws are tight.

Step 6

Fold and position the new 26way harness as
shown plugging it into the CPU, Connector and
DR-link cards. Fold the excess back over the
CPU circuit as shown for the DR66.

Make sure the harness pins are correctly
aligned with the mating connector pins. Push
the plugs fully home.

Check that the harness is neatly folded with the
pin 1 red stripe correctly positioned as shown.

Step 7

Check your work and refit the top cover.
Power up the DR66/128 and check that it boots
up correctly.
