• When you have identified the noise source, install a FilterLinc to isolate the noise source from the INSTEON
network.
Determining Source of Signaling Problems
• A problem area would be an outlet in which the tester has difficulty talking to the unit under test.
• Enable DISTANCE mode.
• Search the following list for your situation:
o No beeping and no On/Off of the device under test.
Make sure device under test is linked as responder to Diagnostic Keypad.
There may not be a signal path between Diagnostic Keypad and device under test.
• Confirm phases are coupled.
• Add dual-band INSTEON products if necessary.
There may be noise at/near the device under test.
• Find and filter the noise-making device with a FilterLinc.
o No beeping, but the device under test goes on and off.
The device under test is receiving the commands but the Diagnostic Keypad is not receiving
the device’s positive acknowledgement that the command was received.
Look for noise at the Diagnostic Keypad’s location. Move Diagnostic Keypad if necessary.
o Beeping, but the device under test doesn’t go on or off.
Acknowledgement may be coming from a different unit. Link to intended device under test.
Try moving Diagnostic Keypad to a different location and using ON/OFF TOGGLE to turn the
device on and off.
Confirm that the device was not linked at off. Turn the device on using its local switch, then
press the ON/OFF TOGGLE button and verify if the device under test turns off but not on. If
linked to off, relink Diagnostic Keypad with device under test set to on.
o The beeping on/off cadence is slower than other outlets.
The path to the device under test is longer, but this may not be a problem.
If the beep cadence is consistent, it’s likely not a problem.
As you use the Diagnostic Keypad, you will be able to more easily recognize the beep
patterns.
o The on/off beeping is spotty at best.
The path to the device under test is poor.
Add additional dual-band INSTEON devices to couple the phases.
There may be noise in the path. Find and filter the noise-making device with a FilterLinc.
