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.
