Crestron C2N-HBLOCK Multi-Type Network Distribution Block
Multi-Type Network Distribution
Block: C2N-HBLOCK
Introduction
The C2N-HBLOCK is a Crestroncontrol network (Cresnet) multiple
connector type, network distribution block that provides wiring for up to
15 devices and/or peripherals. The C2N-HBLOCK provides 24 volts
direct current (VDC), Cresnet Y and Z data signals, and ground through
three different types of Cresnet connectors. Using any one of the
connectors as an input source, the remaining connectors may be used as
outputs to other equipment. The C2N-HBLOCK contains light-emitting
diode (LED) indicators that monitor the input power and input data
signals.
Functional Summary
• Provides wiring for up to 15 devices and/or peripherals
• Three different types of Cresnet connectors, all of which are in
parallel
- Eight 3.5mm 4-pin screw terminal connectors (mini Cresnet)
- Five 5mm 4-pin screw terminal connectors (standard Cresnet)
- Three 6-pin RJ11 modular connectors
• Two LEDs enable user to diagnose wiring problems

Physical Description
The C2N-HBLOCK, shown below and on the next page, is housed in a
black enclosure with silk-screened labels. The front panel contains 16
connectors that are used to input power and Cresnet data signals to the
C2N-HBLOCK and output the same to Cresnet devices. All connectors

C2N-HBLOCK
There are three LEDs on the front panel of the C2N-HBLOCK. The LED
labeled POWER illuminates when 24VDC is attached to one connector
and is available at the remaining connectors. The Yand Zdata signal
LEDs are used to diagnose wiring problems of the data signal input to the
C2N-HBLOCK. Refer to “Y and Z LED Illumination” on page 9 for
further information.
The C2N-HBLOCK mounting plate allows the unit to be installed into
any location that is convenient for Cresnet wiring. The mounting plate
can be removed to install the C2N-HBLOCK onto the CNXRMAK,
Crestron Rack Mount Kit (not supplied). The CNXRMAK is then
installed into a standard 19-inch wide equipment rack. Refer to “Rack
Installation” on page 5 for details.
NOTE: The CNXRMAK occupies two rack spaces (2U).

C2N-HBLOCK Ports
The C2N-HBLOCK contains three types of ports that are connected in
parallel. The eight 3.5mm, 4-pin connectors (labeled 1,2,3,4,5,6,7 and
8) and the five 5mm, 4-pin connectors (labeled A,B,C,D and E) are
used to connect the C2N-HBLOCK to other four-wire Cresnet devices.
The three 6-pin RJ11 modular ports (labeled a,b and c)are used to
connect the C2N-HBLOCK to modular devices in the Cresnet system.
Only one port (any of the three types) is used as an input source and the
remaining ports are used as outputs.
CAUTION: Do not connect or daisy-chain more than one power
input (power pack or power supply) to the C2N-HBLOCK. Multiple
power inputs may damage one or more power packs and/or power
supplies.
NOTE: When using the C2N-HBLOCK to output power to other
devices, do not exceed the maximum capacity of the power pack or
power supply. Calculate and add the total power requirements for all
devices drawing power from the C2N-HBLOCK. If necessary, use
additional C2N-HBLOCKs and power packs or power supplies.
C2N-HBLOCK Indicators
There are three LED indicators located on the C2N-HBLOCK front
panel. The LEDs are described in the next three paragraphs.
POWER
This LED (green) is brightly illuminated when Cresnet 24VDC power
is supplied to the C2N-HBLOCK and available at the remaining
connectors.
Y
During normal operation, this LED (red) is brightly illuminated when
the C2N-HBLOCK receives the correct Cresnet Ydata signal. If this
LED is anything other than brightly illuminated, refer to “Y and Z LED
Illumination” on page 9 for further information.
Z
During normal operation, this LED (red) is dimly illuminated when the
C2N-HBLOCK receives the correct Cresnet Zdata signal. If this LED is
4 •Multi-Type Network Distribution Block Operations & Installation Guide – DOC. 8157A

Crestron C2N-HBLOCK Multi-Type Network Distribution Block
anything other than dimly illuminated, refer to “Y and Z LED
Illumination” on page 9 for further information.
Industry Compliance
As of the date of manufacture, the C2N-HBLOCK has been tested and
found to comply with specifications for CE marking and standards per
EMC and Radiocommunications Compliance Labelling (N11785).
Installation and Wiring
Installation
The C2N-HBLOCK may be installed into any convenient location by
securing the unit’s mounting plate with screws (not supplied) or into a
19-inch rack by using a CNXRMAK, Crestron Rack Mount Kit (not
supplied). To install the C2N-HBLOCK via the mounting plate or into a
rack, refer to the appropriate subsection.
Mounting Plate Installation
To install the C2N-HBLOCK via the mounting plate, attach the mounting
plate to a convenient location and anchor the unit with a screw through at
least one hole in each corner (mounting screws are not supplied). It is
recommended to install the C2N-HBLOCK in an area where the
connectors are accessible and LEDs are visible.
Rack Installation
The C2N-HBLOCK may also be installed into a rack by using a
CNXRMAK (not supplied). Perform the following steps to install the
C2N-HBLOCK into a rack. The only tool required for this procedure is a
#2 Phillips screwdriver.
1. Using a #2 Phillips screwdriver, remove the four mounting
screws (shown below) that secure the mounting plate to the
C2N-HBLOCK and remove the plate.

2. For further instructions, refer to the latest revision of the
CNXRMAK Installation Guide (Doc. 8156). This document
can be obtained from the Downloads | Product Manuals section
of the Crestron website (www.crestron.com).
Network Wiring
CAUTION: Use only Crestron power supplies for Crestron equipment.
Failure to do so could cause equipment damage or void the Crestron
warranty.
NOTE: For larger networks (i.e., greater than 28 network devices), it
may be necessary to add a Cresnet Hub/Repeater (CNXHUB) to maintain
signal quality throughout the network. Also, for networks with lengthy
cable runs or varying types of network devices, it may be desirable to add
a hub/repeater after only 20 network devices.
NOTE: When installing network wiring, refer to the latest revision of
the wiring diagram(s) appropriate to your specific system configuration,
available from the Downloads | Product Manuals | Wiring Diagrams
section of the Crestron website (www.crestron.com).
