Terminating the CAT 5 Cable
The HAL System wiring complies with the standard CAT 5 T568-A or T568-B termination. You can use
a CAT 5, a CAT 5e, or a CAT 6 cable (UTP and 24 AWG). To comply with the FCC and European emis-
sions standards, you
must
use cable for all DR and RAD devices that has screened twisted pairs (four
unshielded twisted pairs surrounded by a single foil shield with a drain wire). This is referred to as
F/UTP, S/UTP, FTP, and ScTP.
You’ll also sometimes see the term STP, although technically this refers to individually-shielded twisted
pairs. For the remainder of this guide, we’ll be using the term CAT 5 to represent all of these choices.
When terminating the cable, it is important to maintain the natural twist of each wire pair as close to the
termination as possible. Use a standard RJ-45 connector to terminate the cable. Note that outputs are
short-circuit protected.
NOTE
:
Here is a bit of trivia for you. What are commonly referred to as RJ45 jacks are not RJ45 at
all but are 8P8C (8 Position 8 Contact) modular connectors. We’ll bow to convention, however,
and use the more recognized term of RJ45.
The following graphic illustrates the T568-B termination and also shows the function of each wire pair
on the HAL System network:
Task 5: Installing and Connecting RADs and DRs
When the CAT 5 cable is in place and the HAL and EXPs (if needed) are installed, connected, and con-
figured, you can begin installing and testing the RADs and DRs. Several installation procedures are
described in this section. The first procedure provides the details of installing and testing RADs and DRs
in a new HAL System. The remaining procedures explain how to replace a RAD or DR in an existing
HAL System.
Before installing the RADs and DRs, you may want to familiarize yourself with their functionality and
hardware features. See "Remote Audio Devices" on page 15 and "Digital Remote Devices" on page 20.
Also, if the audio designer did not provide you with labels for the RADs (and if you have not yet gen-
erated labels), you may want to print them before beginning the installation process. See "Generating
Device Labels" on page 45 for details.
NOTE
:
When installing and testing RADs and DRs in a new HAL System, double-check that the
HAL is connected and powered on (and, preferably, configured) before beginning the RAD/DR
installation.
