Multi-Type Network Distribution Block: CNHBLOCK
Operation & Installation Guide - DOC. 8157
NOTE:
When using the CNHBLOCK 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 CNHBLOCK. If necessary, use
additional CNHBLOCKs and power packs or power supplies.
If making four-wire connections to Cresnet devices, review the latest revision of the network
interconnection drawing (Doc. 5411). The document can be obtained from the Downloads
page (CABLES and MANUAL Libraries) of Crestron’s website (www.crestron.com). Search
for CRESNET.PDF. New users are required to register in order to obtain access to the FTP
site.
If making category 5 connections, refer to the latest revision of the Cresnet Mini Network
CAT 5 Interconnect Drawing (Doc. 5819). This document can be obtained from the
Downloads page (CABLES and MANUAL Libraries) of Crestron’s website
(www.crestron.com). Search for CAT5.PDF.
If making modular connections to devices in the Cresnet system, review the latest revision of
the Network Modular Cable Requirements (Doc. 5682). This document can be obtained from
the Downloads page (CABLES and MANUAL Libraries) of Crestron’s website
(www.crestron.com). Search for MODULAR.PDF.
CAUTION:
Crestron modular cables are rated for a maximum of
two (2)
amperes. Do not
exceed this current capacity for any modular device. If more current is required, connect an
appropriate external power pack to the modular device.
NOTE:
Use only Crestron modular cables when making connections to the CNHBLOCK
modular ports. DO NOT use standard, modular 6-conductor telephone cables. Most telephone
cables are wired in a crisscross fashion and are not compatible with Crestron equipment.
