5
6) Global IR Output - A 3.5mm jack provides all IR codes that the HT-MSU generates
and all IR codes that come in through the IR Input connection and can be configured via Niles
QuickConfig Software for Normal or High output. Normal output is designed for a Niles MF1 IR
MicroFlasher
®
; high output is designed for a Niles IRB1 High-Output IR Flasher
7) RF Antenna Socket - The BNC connector accommodates the supplied antenna. The
antenna must be installed perpendicular to the ground for best results. A 10 ft. (3 meter) antenna
extension cable and mounting bracket are included if remote installation of the antenna is necessary.
The antenna is used when the HT-MSU is being controlled via a Niles compatible RF Remote
8) Status 12V or Video - Six video and voltage-sensing RCA synch inputs for sources
1 through 6 detect when a source is on/off for reliable system activation
9) Status 12V - Two voltage-sensing 3.5mm jacks for sources TV/7 and RCV/8 detect when
those sources are on/off for reliable system activation
10) Power 12V DC - A barrel connection for the provided 12V DC power supply
11) Diagnostic - A USB A connection for Niles Service Center
12) PC Connection/Expansion - A RJ45 connection used to plug in a computer for
system configuration programming or expanding the system design out to future Niles multizone
receivers. Niles QuickConfig PC Configuration Software is used for system configuration
13) RF Test - A 3.5mm jack used to connect the optional Niles IR/RF tester for testing RF reception
SYSTEM DESIGN CONSIDERATIONS
The Niles HT-MSU Home Theater Main System Unit is a highly flexible tool that allows system
designers to create home theater systems that will delight their customers. The following section
explains just some of the system design features of the Niles HT-MSU Home Theater Main System
Unit. To fully understand the system configurations, it’s important to understand the basic control
sections of the HT-MSU.
IR INPUT PORT
This connection is used to control the HT-MSU and all of the home theater sources connected to
it. Each of the system configurations that follow must include an Infrared Sensor connected to this
port and a learning remote programmed with the Niles HT-MSU codes or the Niles R-8 Remote
control. This port also allows for IR pass-through of IR codes from the original remotes of the
connected sources. (Refer to the Accessories section on page 19 for more information on Niles IR
sensors.)
