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

C2N-HBLOCK.

Specifications of the C2N-HBLOCK

SPECIFICATION DETAILS

Height: 1.27 in (3.23 cm)

Width: 5.55 in (14.10 cm)

Depth: 3.30 in (8.38 cm)

Weight: 0.68 lb (0.31 kg) *

Dimensions & Weight

* The weight listed is for the C2N-HBLOCK and all supplied 4-pin

connectors.

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

are internally wired together in parallel. Although not shown, all 4-pin

connectors used to attach the Cresnet wiring to the C2N-HBLOCK are

supplied but Crestron modular cables are not. The large rear panel has

holes and serves as a mounting plate.

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.

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.

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).
