Crestron CAEN-BLOCK Installation Manual

Introduction

Crestron Network Block (CAEN-BLOCK) is a
termination block that provides four termination ports for

Cresnet wiring. The unit can be installed into a Crestron
Automation Enclosure (CAEN-Series) to continue the
connectivity of Cresnet from an enclosure that contains a
Crestron Professional Automation Computer (PAC2) or
any 2-Series processor.
The unit also has two 5-pin connections that provide
communication to the modules. Contact closure override
signals that produce an emergency over ride of the
modules are also sent through these connections.
The unit is a pass-through device with a Cresnet power
factor of zero.

NOTE: Unless otherwise indicated, the lighting
system specified in this guide is modular, requiring
assembly in the field by a licensed electrician, in
accordance with all national and local codes.
If you require a UL Listed panel, Crestron offers this
service through its UL Listed panel shop. This
includes complete in factory system configuration
and assembly by Crestron for an additional fee.
Wiring
The CAEN-BLOCK distributes 24 volts direct current
(VDC), Cresnet Y and Z data signals, and ground. Using
any one of the NET connectors as an input source
(receiving power, data, and ground from a PAC2), the
remaining connectors may be used as outputs to other
equipment (i.e., CAEN-BLOCKs in other enclosures or
other Cresnet devices) to continue the connectivity of
Cresnet from an enclosure that contains a 2-Series
processor to other Cresnet devices.
Attach the module interconnect cable (supplied) to
connect the CAEN-BLOCK to the Crestron lighting
modules (CLX-Series) installed in the enclosure.
NOTE: When making the connection to a module in
a single-wide enclosure, be sure to use the 5-pin
module interconnect connector marked LEFT as
shown in the illustration below.
When a switch contact closure is received between the
"G" connections and the "L" or "R" connection (R is used
in a double-wide enclosure only) on the CAEN BLOCK,
the respective left or right column of modules will set the
lights to the programmed emergency over-ride state.
