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.
