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.
