HT-MSU  
 
INTRODUCTION  
Thank you for purchasing the Niles HT-MSU Home Theater Main System Unit. The HT-MSU  
addresses an essential need of today’s consumers—the ability to easily control and manage the  
assortment of entertainment sources found in the home theater environment.  
Home theater systems are often controlled entirely by the remote. The result is a big, bulky, remote  
control with small, complicated buttons or screens that only a “mad scientist” could figure out. The  
Niles Home Theater Main System Unit (HT-MSU) ends the confusion by placing power and control  
in an interface box and using the remote to “trigger” desired activities.  
The Niles HT-MSU can be used with the Niles R-8 Handheld IR Remote Control or any learning  
IR remote control programmed with Niles single-touch activity keys. With the Niles HT-MSU,  
users gain levels of control that are simply not possible with traditional “universal” remotes.  
Infrared, RS232, voltage triggers, and contact closures make the HT-MSU a complete control and  
automation system for displays, surround receivers, cable boxes, satellite receivers, DVD players  
and more. In addition, the HT-MSU can automate functions like lighting control, TV lifts, draperies,  
and projection screens.  
Home entertainment systems should be fun, not frustrating, and Niles has always recognized the  
need for simple-to-use, cost-effective solutions. The Niles HT-MSU Home Theater Main System  
Unit gives end users one-touch control of their home theater systems and reflects the high quality  
fit and finish that meets the standards of today’s consumers.

FEATURES AND BENEFITS  
SIMPLE CONTROL OF COMPLEX SYSTEMS  
The Niles HT-MSU Home Theater Main System Unit simplifies entertainment by allowing one-touch  
control of home theater components. Ordinary home theater system controllers require users  
to turn on (and off) multiple components, resulting in a confusing situation of hunting down the  
fugitive component that is “off,” when it really should be “on.”  
The HT-MSU eliminates the confusion by shifting control to an interface box. The remote initiates  
commands to the HT-MSU, so whether you’re playing a DVD or watching a program recorded on  
your DVR, the HT-MSU provides one-touch access to all your entertainment.  
INTELLIGENT MAIN SYSTEM UNIT  
The HT-MSU incorporates an infrared sensor port to control sources that use original remotes  
or “all-in-one” programmable universal remotes, even if the system is hidden from view. The  
HT-MSU has both video and 12 Volt sync inputs to manage the “power state” of your home theater  
system components. These synch ports, along with IR flasher ports, RS232 control ports, and an  
expansion port, allow the HT-MSU to control up to 22 devices from your home theater system and  
even “share” sources with a house-wide distributed audio system. The HT-MSU also includes “dry  
contact closure” relays and 12V trigger outputs that can be used to control devices like projector  
lifts, screens, drapes or lighting. An ethernet expansion port is also included for system expansion,  
communication to Niles MultiZone Receivers, and future upgrades.  
INSTALLATION FLEXIBILITY  
With a low profile design, easy-to-access connections, and rack-mount-hole wings, the HT-MSU  
can be wall-mounted behind theater components or attached to the back of metal professional  
racks.  
QUICK AND EASY SET-UP WITH WIZARD-BASED NILES  
QUICKCONFIG™ PC CONFIGURATION SOFTWARE  
An HT-MSU configuration can be programmed, saved, and edited using the Niles QuickConfig PC  
Configuration Software and Niles IR-CS Infrared Capture Station. The QuickConfig PC Configuration  
Software is Wizard-based and guides the installer/programmer through basic and advanced  
system designs.  
ASSIGNABLE RELAYS AND 12V OUTPUTS  
Three dry contact closures and three 12V DC trigger outputs can be independently programmed  
to give installers greater control of mechanical devices or voltage-triggered power strips and  
dispersion controlled home theater loudspeakers.

INTELLIGENT INTEGRATION WITH MULTI-ZONE SYSTEMS  
The HT-MSU includes control ports that allow it to “share” sources with whole-house distributed  
audio systems. The power state of these “shared” sources can be completely managed so that  
sources are always powered-on when they need to be and powered-off when both whole-house  
and home theater systems are turned off.  
PROGRAM MEMORY PROTECTION  
The entire system profile is stored in non-volatile memory within the HT-MSU. This safeguards  
against accidental loss of the configuration programming.

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.)  
NILES AUDIO CORPORATION – 1-800-BUY-HIFI – 305-238-4373

IR OUTPUT PORTS  
IR (Infrared) codes are stored in the HT-MSU during configuration programming. The labels of the  
IR Outputs identify what source number these ports are designed to operate. SRC1 means source  
1. The outputs are labeled SRC1 through SRC6, TV/7 and RCV/8. If the TV is to be controlled via  
IR codes, then the IR Output TV/7 port should be used. However, if the TV will be controlled via  
RS232, then the TV/7 IR output can be used to control an alternate IR source. These IR outputs are  
dedicated and routed, meaning IR codes stored for source number 3 (i.e., a DVD player) can only  
be emitted from the IR output port labeled SRC3. RCV/8 can be used either for the receiver in the  
home theater or a source number 8.  
RS232 OUTPUT PORTS  
RS232 is a serial device control protocol that allows sources to be controlled via a transmit-receive  
cable. (See the Installation section for wiring information.) RS232 codes are stored in the HT-MSU  
as string codes during configuration programming. The labels of the RS232 Outputs identify what  
source number they are designed to operate. SRC1 means source 1. The outputs are labeled SRC1  
through SRC6, TV/7 and RCV/8. If the TV is to be controlled via RS232 codes, then the RS232 TV/7  
port should be used. However, if the TV will be controlled via IR, then the RS232 TV/7 port can  
be used to control an alternate RS232 source. These RS232 outputs are dedicated and routed,  
meaning RS232 codes stored for source number 3 (i.e., a DVD player) can only be emitted from|  
the RS232 output port labeled SRC3. RCV/8 can be used either for the receiver in the home theater  
or a source number 8.  
SOURCE POWER STATUS CONNECTIONS  
To properly automate home theater sources, the HT-MSU needs to “know” when the source is  
powered On or Off. There are three ways that sources are powered on:  
1. Toggle Power: A source via its remote control has one button for turning that source  
On and Off. When trying to automate such a device, you must provide the HT-MSU the  
“Power Status” as feedback using the Status connection on the HT-MSU’s top edge  
(detailed below).  
2. Separate On and Off Power: A source via its remote control has one button to turn  
the source On and a different button to turn the source Off. When trying to automate  
such an IR device, you should provide the HT-MSU the “Power Status” as feedback so  
the IC2 System will act faster using the Status connection on the HT-MSU. If a source  
is to be controlled via RS232 and it has separate On and Off codes, you do not need to  
provide the HT-MSU feedback.  
3. Latching Power: Latching power is an industry term that means the source has no  
power command/s on its remote control. A latching power source may have a “hard”  
power button on the front panel. To determine if a source is latching power, push its  
“hard” power button in, take its power cord and plug it into a live AC power outlet. If  
it turns on when plugged into the outlet and turns off when unplugged from the outlet,  
it is a latching power source. Latching power sources do not need a Power Status  
6
 
connection, but you will want to do one of two things:  
a. Plug it into the switched outlet of the receiver, or  
b. Use a Niles AC-3 Voltage Triggered Power Strip connected to one of  
the assignable 12V outputs on the HT-MSU. Use the QuickConfig PC  
Configuration Software to program the assigned 12V output to turn on  
when that source is selected. (See QuickConfig manual for more details on  
programming 12V outputs.)  
Along the top edge of the HT-MSU are the source-specific status connections labeled  
SRC1 through SRC6. These RCA jacks are designed to sense either 12 Volts or video  
so the HT-MSU “knows” when the source is On or Off. You must use these connections  
if the source you are trying to automate is IR controlled and uses toggle power  
(see 1.Toggle Power above).  
If the source has a video out jack, connect the video output to the corresponding SRC  
Status RCA jack on the HT-MSU. If the source has no video output jack, you may use one  
of the Niles external-sensing devices that provides 12V output (i.e., the CS12V Current  
Sensor or the LS-1 Light Sensor) connected to the RCA Status jack.  
ASSIGNABLE 12 VOLT OUTPUTS  
These three ports are completely assignable and can be used to trigger out-board automation  
devices such as:  
• 12V Triggered AC Power strips like the Niles AC-3  
• 12V Triggered subwoofers like the Niles SW300, SW12, SW10, and Pro15SW  
• 12V Triggered Dipole/Bipole rear effects speakers like the StageFront IW650FX  
• Motorized drapery systems and projection screens  
12V Output #1 has a default setting to output 12V DC whenever the home theater receiver is turned  
on by the HT-MSU Master Key activity setting.  
12V Output #2 has a default setting to output 12V DC whenever the HT-MSU Master Key activity  
setting turns on the TV.  
12V Output #3 has no default and is completely assignable.  
The three assignable 12V outputs can be configured (programmed) using the Niles QuickConfig  
PC Configuration Software.  
ASSIGNABLE RELAYS  
There are three independently assignable dry contact closures/relays. These connections can be  
used to trigger lights, curtains, screen lifts, and other devices. Use the Normally Open or Normally  
Closed side of the contact closure to complete the circuit to control the device.

In System Configuration #1 (Figure 2), a Niles IR sensor must be connected to the IR sensor in-  
put and a learning IR remote (programmed with the HT-MSU codes) is used to activate the HT-MSU.  
In this configuration, a flat panel TV is controlled via the RS232 connection TV/7 on the HT-MSU.  
A motorized lift to raise and lower the TV is being activated with the programmable Relay #1. The  
surround receiver is being controlled via IR flasher connected to the RCV/8 connection on the  
HT-MSU. The surround receiver’s power status is being monitored by a Niles 12V DC power supply  
plugged into the receiver’s switched AC outlet and then plugged into RCV/8 Status 12V connection  
on the HT-MSU. In addition to the TV and receiver, there are five sources. The DSS Satellite receiver  
is being controlled via IR from the IR SRC1 port. There is no status connection to the HT-MSU be-  
cause it has separate On/Off codes. The Media Server is being controlled via the RS232 SRC2 port.  
The DVD player is being controlled via the IR SRC3 port, and a CS12V Current Sensor connected  
to the SRC3 Status RCA jack is providing the status. IR connected to the IR SRC4 is controlling the  
portable Music Player in its dock, and video is providing the status connected to the SRC4 Status  
RCA jack. IR connected to the IR SRC5 port is controlling a latching power CD player and, using the  
12V Output # 1, triggering a Niles AC-3 to power it On and Off.

Figure 3. System Configuration 2  
System Configuration #2 (Figure 3) demonstrates the Dual TV Mode feature of the iC2 System.  
The flat panel TV is controlled via RS232 on the HT-MSU RS232 TV/7 port. This is considered the  
default TV. The customer also has a projector and screen used only when the theater room is dark.  
The projector is configured (programmed) with Niles QuickConfig PC Configuration Software to be  
TV2 and is wired for IR control to the HT-MSU IR SRC1 port. The Status of TV2 is connected to the  
HT-MSU IR SRC1 RCA connection using the 12V output of the projector (usually used to trigger the  
screen). The projection screen is being triggered by the HT-MSU 12V Output #3. When the first Mas-  
ter Key on the iC2 Remote is pressed from an all-off mode, the default TV (the flat panel TV, TV1)  
is turned on. Master Key 8 is labeled SWAP TV. When the SWAP TV Master Key is pressed, TV1 (flat  
panel) is turned off and TV2 (the projector) is turned on, and the screen is lowered for viewing. The  
Dual TV Feature is not limited to IR controllable TVs. Either TV can be RS232 controllable.  
NOTE: IN DUAL TV MODE, ONLY ONE TV IS ON AT A TIME. BOTH TVS CANNOT BE ON AT THE SAME TIME.

System Configuration #2 also shows an RS232 controllable lighting system connected to the  
HT-MSU RS232 SRC6 port. In this configuration, there are 2 sources (a DVD and a DSS satellite  
receiver) being “shared” with the house-wide multizone distributed audio receiver. The HT-MSU  
sends IR codes for both of the shared sources out of the Global IR Output port into the multizone’s  
IR IN port. The HT-MSU’s 12V Output #1 is connected to the multizone’s HT SYNC port, which  
ensures that the “shared” sources are turned On and Off correctly. The multizone “knows” that  
the home theater system is On or Off via this 12V connection.

System Configuration #3 (Figure 4) shows two more system design features of the Home  
Theater Main System Unit. The HT-MSU has a design feature called TV Array. Here, a Niles PAR4  
Simplified IR Router is used with the HT-MSU to control an array of identical televisions. (In order  
to use the TV Array feature, all of the TVs must be identical or respond to the same IR codes.  
Additionally, the TVs must have separate On and Off power commands and direct access input  
commands.) A Niles 3.5mm to 3.5mm cable connects the PAR4 to the HT-MSU’s IR TV/7 port. On  
the Niles PAR4, Niles MicroFlashers are connected to the numbered outputs 1 through 4. The main  
TV should be connected to the PAR4 #1 output. When the end user presses any Master Key from  
an All Off situation, the Main TV (PAR4 #1) turns on. Master Key 8 is labeled TV Array. Press the TV  
Array Master Key (Master Key 8), then press one of the number keys 1, 2, 3 or 4. This allows the  
end user to control that TV in the array of TVs. Two Niles PAR4’s can be used for a maximum of  
eight TVs in the TV array.

INSTALLATION CONSIDERATIONS  
PLACEMENT OF THE HT-MSU  
Niles recommends placing the HT-MSU conveniently  
close to the equipment it is controlling. Generally, the  
unit should be placed in a concealed location because  
its indicator and connections are only used during  
installation. Placement possibilities include:  
1) Wall-mount (affixed to the back of the equipment  
cabinet or a nearby wall) (Figure 5)  
Figure 5. Wall-mount placement.  
2) Rack-mount (attached to the back of a professional  
19-inch standard equipment rack that uses traditional  
1, 2 or 3 “u” hole spacing (e.g. Middle Atlantic)  
Use sheetrock screws  
3) Table-top (on the floor or shelf behind the equipment)  
WIRING CONSIDERATIONS  
The HT-MSU requires several different types of wires runs:  
1) IR Sensor Wire: The HT-MSU has an infrared (IR) sensor input for connection to any type  
of Niles IR sensor. Niles IR sensors utilize 4-conductor wiring and have been designed  
for use with CAT-5 cable (4-pair twisted) (Figure 6).  
2) Flasher Cable: Niles infrared flashers (not supplied with the IC2 System) include  
a 10 foot cable. Flasher wires can be extended up to 200 feet using  
2-conductor 22 gauge (“zip-cord”). Shielding is not necessary  
for a flasher.  
Remotely Located  
IR Sensor  
Sensors In  
3) RS232 Cable: The HT-MSU can control home  
theater sources using one-way RS232 control  
cable. Niles does not supply RS232 cables. Home  
theater sources that are RS232 control capable  
will usually supply or recommend the wire  
and the pin-out that will control their devices.  
Traditionally, RS232 one-way communication  
can be sent over three wires (transmit, receive  
and ground), but not for very long distances.  
(Niles recommends placing the HT-MSU in  
close proximity to the sources it  
CAT-5  
Figure 6.

to the HT-MSU  
is controlling.)  
NILES AUDIO CORPORATION – 1-800-BUY-HIFI – 305-238-4373  
11  
 
4) Status Wiring: The Niles HT-MSU has status (power synchronization) ports for eight  
home theater sources. The status connections for sources 1 through 6 (labeled SRC1  
– SRC6) are RCA jacks that can sense video or a 12V DC voltage signal. The TV/7 and  
RCV/8 (receiver) status connections are 3.5mm jacks that sense voltage signals. When  
using video for status, a standard RCA cable can be used from that source. Alternatively,  
when using 12V for status, a standard 22 gauge, 2-conductor cable (“zip-cord”) can  
be used. Niles Accessory Cables (FG00724 or FG00933) can also be used (SEE THE  
ACCESSORIES SECTION FOR MORE INFORMATION).  
TECH TIP  
WIRE SIZE IS EXPRESSED BY ITS AWG (AMERICAN WIRE GAUGE) NUMBER THE LOWER THE  
NUMBER, THE LARGER THE WIRE, FOR EXAMPLE, 20 AWG IS PHYSICALLY LARGER THAN 22 AWG.  
5) 12V Output and Relay Wiring: The HT-MSU has three 12V and three “Dry Contact  
Closure” Relay Outputs that can activate mechanical devices such as motorized drapery  
and projection screen systems, as well as a number of other automation devices. For  
each device these outputs will control, standard 22 gauge 2-conductor cable (“zip-  
cord”) can be used. Niles Accessory Cables (FG00724 or FG00933) can also be used.  
Each relay is rated to handle 12V DC, up to 5 amps. (SEE THE ACCESSORIES SECTION  
FOR MORE INFORMATION).  
6) Expansion Cable: The HT-MSU has an Expansion connection that can be used to extend  
the built-in RF radio away from the HT-MSU and/or for connection to and “sharing”  
sources with future Niles multizone receivers (SEE SYSTEM CONFIGURATION #3 IN THE  
SYSTEM DESIGN CONSIDERATIONS SECTION). This cable must be CAT-5 terminated  
with RJ45 connectors (T568A TERMINATION PROTOCOL IS SHOWN IN THE INSTALLATION  
SECTION 7).  
7) Antenna Cable: The supplied extension cable is 10 foot long and is a RG59 CL rated  
cable so it can be run through the wall. Extending the cable or using longer cable is not  
recommended as this will drastically affect the RF reception. The antenna is only used  
if a Niles RF Remote issued to control the HT-MSU.  
PROGRAMMING PREPARATIONS AND WORKSHEET  
The HT-MSU has a PC Configuration/Expansion port on the bottom edge that is used for configuring  
(programming) the system. If the HT-MSU is being used by itself, the PC Configuration/Expansion  
port will be empty and used to program the system (Figure 7).  
A Worksheet is provided with the HT-MSU Home Theater Main System Unit and should be used  
to organize all of the information an installer will need to configure the HT-MSU. The HT-MSU  
worksheet is also available on the Niles website: www.nilesaudio.com.

HT-MSU TRIGGERING REMOTE CONTROL CONSIDERATIONS  
Choosing the right IR remote to trigger the HT-MSU is very important. The HT-MSU is a component  
in the Niles IC2 Home Theater Automation and Control System. This system consists of the  
HT-MSU, the IC2 Remote, and a Zigbee RF remote that sends RF commands to the HT-MSU  
to trigger the activities.  
When choosing an IR Remote, consider the functions of the IC2 Remote that you want to duplicate.  
The IC2 Remote uses eight Master Keys (Activities or Sources) and 36 function keys for each of the  
Master Keys. The IR remote you choose should have the following features:  
1. Eight Source buttons that can be programmed with the Niles Master Key commands.  
2) Function Keys broken into the following categories:  
a. Transport functions (Play, Stop, Pause, Fast Forward, Rewind and Record)  
b. Numeric access the (numbers 1-0, Last, Enter and Favorites/Presets)  
c. Menu Navigation functions (Cursor keys, Select, Guide, Info, Exit, menu  
application-specific keys Red, Green, Yellow and Menu)  
d. Volume up/down, Mute and Channel up/down

INSTALLATION  
Before you begin, make sure that all of the cables and wires, as well as the power supply cable will  
reach the proposed location of the HT-MSU. Mark the cables with labels that describe where the  
cable originates (rather than which terminal on the HT-MSU it connects to).  
STEPS:  
1) CONNECT POWER TO THE HT-MSU. CHECK LED, DISCONNECT POWER  
Plug the supplied 12V DC power supply into an unswitched AC outlet. Plug the connector  
into the socket marked “Power” on the HT-MSU. If the Power LED does not light, test the  
unswitched AC outlet with another appliance. If the outlet tests OK, you have a defective  
power supply, which must be replaced for you to continue. Once you have completed  
the power supply test, unplug the power supply and continue hooking up the rest of the  
wires and cables.  
2) CONNECT THE SENSOR CABLE TO IR INPUT  
Strip 1/4 inch of the insulation from the end of each wire.  
Tightly twist the end of each wire until no frayed ends  
remain. Use a small flathead screwdriver or your fingernail  
to raise the locking tabs, exposing the holes on the  
removable connector. Insert each wire into the appropriate  
hole on the removable connector plug (Figure 8) and  
snap the locking tab down. To help you, the connector plug  
is keyed. Insert the smooth side of the connector plug into  
the smooth side of the socket.  
Figure 8.

3) CONNECT ALL FLASHERS  
Route the connecting wire to the HT-MSU. Connect  
the 3.5mm mono plug into the corresponding SRC jack  
labeled “IR Output” from the installation worksheet.  
If you need to extend the wire, use a 2-conductor 16  
gauge or larger (SEE “TECH TIP ON PAGE 12).  
Figure 9.  
Flasher connection

4) CONNECT ALL RS232  
The RS232 Output jacks use 3.5mm STEREO plug with standard TRS (Tip, Ring and Sleeve)  
configuration of Transmit, Receive, and Ground. This may require the installer to custom-  
make the connection to the corresponding source. Most RS232 controllable sources use  
one of the following as its RS232 input connector:  
a) A Male DB9 connector  
b) A Female DB9 connector  
c) A 3.5mm stereo input jack  
Most sources that are RS232 controllable provide a protocol document (usually from their  
Tech Support Department) that will have all of the necessary information, including pin-out,  
to custom build the RS232 control cable (Figure 10).

5) CONNECT ALL STATUS  
There are two types of status (power synchronization) ports on the HT-MSU: the TV/7  
and RCV/8 status connections are 3.5mm mono ports; and SRC1 through SRC6 status  
connections are RCA jack ports. The TV/7 and RCV/8 status connections are voltage-  
sensing ports “looking for” 12V DC Volt input. The most common technique for “synching”  
the home theater receiver is to use a Niles 12V (FG01035) power supply plugged into the  
receiver’s switched outlet, and plugging the 3.5mm jack into the RCV/8 Status connection  
port. The most common way to “synch” the TV (which usually doesn’t have a switched AC  
outlet on the back) is to use one of the Niles synching accessories like the CS12V Current  
Sensor or LS-1 Light Sensor. Both of these synching accessories have 12V outputs that can  
be connected to the HT-MSU using a 3.5mm mono jack plugged into the TV/7 status port.  
The SRC1 through SRC6 RCA connections are RCA jack ports that are “looking” for either  
voltage or a video signal from the source. If a DVD is to be hooked up as SRC2 (use the  
worksheets to help with source connection layouts), an RCA video cable would be used  
to connect the DVD’s composite video output to the SRC2 RCA Status connection port.  
If the DVD has only one composite video output, and that is being used to show video  
on the TV, an RCA Y-adaptor can be used to split the video output (of the DVD) for both

the TV signal and Status connection to the HT-MSU (Figure  
11).If the source to be “synched” doesn’t have a video output,  
one of the Niles Synching Accessories can be used instead of  
video. Most Niles Synching Accessories use a 3.5mm jack as the  
output. This 3.5mm jack must be changed to mate with the RCA  
connector on the HT-MSU; use a Radio Shack 274-897 OR 274-  
330 mini-plug to male RCA adapter.  
IMPORTANT NOTE: RCA SOURCE STATUS INPUTS ARE DESIGNED  
WITH HIGH-INPUT IMPEDANCES IN ORDER TO PRESERVE THE  
QUALITY OF THE VIDEO SIGNAL WHEN USING A RCA Y-ADAPTOR.

6) CONNECT 12V  
The 12V trigger output jacks use 3.5mm mono plug with standard  
“Tip and Collar” configuration. The tip is 12V DC 150mA when activated and the collar is  
ground. Niles has two accessory cables for use with these 12V output jacks (FG00724 or  
FG00933). Simply plug one of these cables with a 3.5mm mono plug into one of the three  
assignable jacks. Plug the other end of the cable into the device that will be triggered or  
activated.  
The Niles QuickConfig PC Configuration Software is used to assign (program) the  
functionality of these jacks. The configuration software allows the 12V output to be  
programmed as follows:  
a) Output #1 can be configured to output 12V constantly or momentarily. A  
momentary output would be used to activate a device that requires a pulse of  
12V instead of a constant 12V. The pulse can be programmed for 1, 3 or 5 seconds,  
then off when activated. The constant mode will output 12V continuously when  
activated, and no 12V when deactivated.  
b) Output #2 can be programmed just like Output #1, but  
completely independent of output #1.  
c) Output #3 configured for constant output only when  
activated, but is also completely independent of outputs 1 and 2.  
Please refer to the Niles QuickConfig Configuration manual for more  
information about the 12V output programmability.

The “Dry Contact Closure” relays use 2-conductor wire to pair  
either the NO “Normally Open” or NC “Normally Closed” side of  
the removable connector plug with the “Common”. NO or NC is  
determined by which device you are triggering. Strip 1/4 inch of the  
insulation from the end of each wire, and tightly twist the end of each  
wire until no frayed ends remain. Use a small flathead screwdriver or

TROUBLESHOOTING  
The HT-MSU Home Theater Main System Unit is a configurable system (i.e., the product arrives  
“empty” and must be programmed by the installer). Troubleshooting generally occurs after the  
HT-MSU is programmed; however, troubleshooting can be divided into two main areas, some of  
which can occur prior to programming:  
1) Hardware Issues  
2) Programming (refer to the Niles QuickConfig Configuration Software Manual for more  
information on programming troubleshooting)  
HARDWARE ISSUES  
There are two basic issues that can prevent proper operation of the HT-MSU system. These issues  
are presented in the order of probability and are as follows:  
PROBLEM:  
1. Bad Connections or Wiring  
If the connections or wiring are wrong, loose, shorted or open, the system will not

17  
 
operate properly. The symptoms could include: Power LED flickers or is off, IR/RF Test  
LED is continuously flickering or on without any Niles RF remote use, intermittent  
operation or no operation.  
SOLUTIONS:  
• Test your power supply connections  
• Test your Flasher connections  
• Test your Sensor connection  
• Test your cable for shorts and opens  
2. Source Powering On or Off Incorrectly  
To automate sources correctly, the HT-MSU requires Status feedback from sources  
that have a single-toggle power command. The HT-MSU either “sees” or doesn’t “see”  
control signals at the Status ports. If the HT-MSU sees improper or intermittent status  
feedback (i.e., the HT-MSU may “think” that the source is off when it may really be  
powered on), the operation of the HT-MSU is compromised.  
The symptoms could include: sources staying on when the System Off button is  
pressed; a source turns on for a Master Key and off when that Master Key is pressed  
again; and sources not turning on at all. The most important tool for troubleshooting  
this issue is knowledge. Knowing the functionality of the sources being used with the  
HT-MSU is paramount. For example, we know that most DVD players require choosing  
composite/component video output, even digital HDMI or DVI output. When set for  
component or digital video output, the composite video output is sometimes disabled.  
If a DVD player is set for digital video output and it disables the composite video output,  
you cannot use the composite video output for status connection to the HT-MSU.  
Because there will never be a signal at the composite output, the HT-MSU will think  
that the DVD is always off and issue the power command. This will cause the DVD  
player to be turned on the first time a Master Key is pressed and turned off the second  
time the same Master Key is pressed.  
Status feedback is tested when configuring the HT-MSU using the Niles QuickConfig  
PC Configuration Software. After the transfer screen in the software, there is a  
Functionality Test Screen that allows the software to test the configuration stored in  
the HT-MSU while providing feedback on the screen of the programming laptop. The  
feedback provided is real-time status feedback for Status Ports SRC1 through SRC6  
as well as the TV/7 and RCV/8 ports. The Functionality Test Screen also allows for  
feedback on the Assignable 12V Output and relay ports.
