CAEN-BLOCK
– Network Block
Introduction
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.
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.
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.
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.
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.
The unit is a pass-through device with a Cresnet power
factor of zero.

Installation
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.
The CAEN-BLOCK must be mounted in accordance with
all national and local codes. Use the two screws (8Bx1/4”,
supplied) to attach a CAEN-BLOCK to an enclosure.
Refer to the two drawings below for location and
orientation within an enclosure.
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.
