DigitalMedia™ Repeater:
DM-DR
Introduction
The DigitalMedia™ (DM) Repeater allows DM cable lengths to be
extended in up to 200 foot increments. Up to three repeaters may be
installed in a single DM cable run to enable cable lengths up to 450 feet.
Refer to the latest version of the Crestron
(Doc. 4789) for more information about DM wiring. It is available from
the Crestron website (
The DM-DR does not simply boost the DM signal, but actually
reproduces a fresh signal to ensure error-free delivery to the following
device. Each DM Repeater mounts to a standard 2-gang, 85mm European
or 4 inch 1900 box electrical box or plaster ring, and extends one inch
(25.4 mm) from the wall surface when mounted.

Uploading and Upgrading
Crestron recommends using the latest programming software and that
each device contains the latest firmware to take advantage of the most
recently released features. However, before attempting to upload or
upgrade it is necessary to establish communication. Once communication
has been established, files (for example, firmware) can be transferred to
the device.
Establishing Communication
Use Crestron Toolbox™ for communicating with the DM-DR; refer to the
Crestron Toolbox help file for details. There is a single method of
communication: indirect communication.
Indirect Communication
PC RUNNING
CRESTRON TOOLBOX
SERIAL,
ETHERNET
OR USB
DM SWITCHER
DM-DR
DMNet
• DM-DR connects to a DigitalMedia switcher via DMNet.
• Establish communication between the PC and the DM switcher
as described in the latest version of a DigitalMedia Switcher
Operations Guide (Doc. 6755).
• Use the Address Book in Crestron Toolbox to create an entry for
the DM-DR using the expected communication protocol
(Indirect). Select the Cresnet ID of the DM-DR and the address
book entry of the control system that is connected to the DM-DR.
• Display the DM-DR’s “System Info” window (click the
icon); communications are confirmed when the device
information is displayed.
Firmware
Firmware files may be distributed from programmers to installers or from
Crestron to dealers. Firmware upgrades are available from the Crestron
Operations & Installation Guide – DOC. 6745A DigitalMedia

Check Network Wiring
In order to ensure optimum performance over the full range of your
installation topology, Crestron Certified Wire and only Crestron
Certified Wire may be used. Failure to do so may incur additional
charges if support is required to identify performance deficiencies
because of using improper wire.
Calculate
Power
CAUTION: Use only Crestron power supplies for Crestron
equipment. Failure to do so could cause equipment damage or void the
Crestron warranty.
CAUTION: Provide sufficient power to the system. Insufficient
power can lead to unpredictable results or damage to the equipment.
The EIG connector on the DM switcher is used to jumper in external
power. Additional power is rarely required; switchers provide enough
power for their maximum configuration of room controllers and
repeaters. Please use the DMNet Power Calculator to help calculate
how much power is needed for the system
