Well, its been a few decades in the making, but I finally bought a new vehicle that has Homelink.
I was successful in programming the left and right Homelink buttons to operate my left and right garage door openers.
But now I want to also program the center Homelink button to operate an X10 unit.
I have the Homelink Vehicle Interface.
I use an extension cord to have the Home Vehicle Interface right in the vehicle with me. I set the Home Vehicle Interface to unit code 1, slide the switch to "install", and press the center button in my vehicle. Nothing.
OK, I see that unit codes 1, 2, and 3 might
be reserved for the garage door status units. So, I change the Homelink Vehicle Interface to unit code 4 and try again. Nothing.
Each time, the Homelink in my vehicle appears to be in Learn or Receive mode. That it wants to be programmed for a third garage door remote. The yellow
LED just slowly blinks. Even after I hold it for 20 to 30 seconds.
I know that X10 instructions in general are notorious in omitting some critical step, assuming the user knows what to do.
How do I get the Homelink in my vehicle to be in, I assume, transmit
mode, such that it transmits the signal that the Homelink Vehicle Interface wants to see and itself install/learn??
Anyone with any personal experience they could share?
