CDR‑1 & CDR‑1F Installation Guide v2.0 3
Introduction
The CDR-1 & CDR-1F are remote control units specically designed for use with the
DCM-1/e. They may be tted to standard electrical back boxes in whatever location is
convenient in each zone.
Model types
The CDR-1 and CDR-1F are electrically and operationally identical, but differ in their
physical dimensions and mounting arrangements.
• The CDR-1 is a surface-mounting unit, which may be mounted via its supplied
mounting plate either to a single-gang back box, or directly to a suitable wall.
Max. projection from the wall is 30 mm.
• The CDR-1F is a ush-tting panel which ts to a standard dual-gang back box.
Max. projection from the wall is 10 mm.
Note: Where the term “CDR” is used in this manual, the text can be taken to apply to
both the CDR-1 and CDR-1F. In the section describing mounting (where the two types
differ), the full product names are used. An exception to this refers to the DCM-1/e’s
remote control ports, which are described as CDR-1 PORTS, to match the labeling
on the DCM-1/e itself.
A zone may have one CDR, more than one, or none at all. The DCM-1/e can support
up to 100 CDRs. CDRs are interconnected with standard CAT-5 UTP cable; units may
be daisy-chained at will and/or connected individually back to the DCM-1/e’s four
CDR-1 PORTS using almost any wiring topology convenient for the installation.
The CDR provides the user with the following local control functions for the zone in
which it is installed:
• Source selection
• Level control
• Group enable/disable (providing the zone has been dened as a group member)
• Local zone EQ adjustment (requires enabling on the DCM-1/e and entry of a key
code)
An Installer Mode permits zone assignment and adjustment of other installation
parameters.

Installation
CDR networks and terminations
CDRs are connected to the DCM-1/e’s CDR-1 PORT sockets using standard
unscreened CAT-5 cable and RJ45 connectors. It may be possible to use pre-made
CAT-5 “patch cables” to connect any CDRs installed close to the DCM-1/e; otherwise
CAT-5 cable and crimp RJ45 plugs should be used.
Note: All CAT-5 cabling should be wired “pin-to-pin”; “crossed” or “null” cables will
not work.
CDRs may be connected to the DCM-1/e either by wiring them directly and individually,
or by “daisy-chaining” them together. In most installations, a combination of these
methods is likely to be the most convenient solution from the point of view of practical
cabling. The diagrams on page 6 illustrate the types of wiring schemes that may be
employed; almost any variation on these is permissible.
Note that the two types of CDR may be intermixed freely as the installation requires.
