Tips for Using Insteon Modem 

 

Do not use a USB cable longer than 10’ (6’ or less is recommended) 

 

NEVER plug Insteon Modem into a power strip or AC line filter 

 

Use only one Insteon Modem per computer 

 

Do not place near large metal objects, such as refrigerators or TVs 

 

Some computers and their accessories can absorb Insteon Carrier (PLC) signals off the powerlines. Since Insteon Modem will 
be close to the computer, the power strip for the computer should be filtered. Use an Insteon FilterLinc (#1626-10) on the 
computer’s power strip to keep Insteon Modem signals from getting absorbed by the computer equipment 

 

To reset Insteon Modem to its original factory settings, unplug from wall outlet and wait 10 seconds. Press and hold Set button; 
while continuing to press and hold, plug back in. A long beep will sound; continue holding Set button until beep stops, then 
release. 

 

After several seconds, status LED will turn on to indicate reset is complete 

 

Use Insteon Modem as a Phase Bridge 

1) 

Install additional dual-band Insteon devices if they are not already installed 

2) 

Start Phase Detection Mode by tapping the Set button on Insteon Modem four times quickly 

Insteon Modem will begin beeping and status LED will turn on solid green  

3) 

Check the LED behavior of the other dual-band devices to see if they are on the opposite phase 

If at least one of the dual-band device LEDs is blinking green or is bright solid white or blue, the device is on the opposite 
phase. Continue on to step 4.

 

If none of the dual-band devices exhibit the behavior above, they are on the same electrical phase. Try the following:  

 

Follow steps 2 and 3 with the other dual-band devices to see if they are exhibiting the desired LED behavior 

 

Move a dual-band device to another location until it exhibits the desired LED behavior 

4) 

Tap Insteon Modem Set button 

Insteon Modem will stop beeping
