X10 has made a change to the XPT bases and the keypads. You need to be sure you have keypads and bases that will work together. The newer version of the keypads and the bases have an "A" designation on them (for example XP4-W A or XPT A). The newer bases look better when they are installed in that they sit back in the wall further giving a more flush appearance with the wall plate. The metal mounting tabs are deeper but the base enclosure is thinner which means that the overall depth of the XPT base is the same as the older version. There's no worry about them not fitting in the electrical box that an older XPT was originally mounted in. The older style stuck out from the wall and honestly looked kinda' stupid. The main difference, electrically speaking, is that the newer version "A" keypads will not work on the older NON "A" bases. Also, the new "A" version XPT bases will not work with the older NON "A" keypads. Why X10 made them electrically incompatible is unknown--it makes no sense to me. They could have saved a lot of problems by making the new bases so they'd work with the older keypads and vice versa. With this change, you have to be certain you have the right keypad with the right base. All of the bases and keypads I carry are the newest version and are all compatible with each other. You can view a more detailed explanation on how to tell if you have "A" or NON "A" keypads and bases by clicking HERE.


This is the newest style "A" version X10 in-wall transmitter base module number XPT. This is for use with the newest version "A" X10 Pro in-wall keypads. This will not work with any of the old style NON-A version keypads.

The XPT base transmitter module wires into a single gang wall box with a simple two wire connection. One wire connects to the AC HOT and the other to NEUTRAL. You set house and unit codes on the base to the first unit code you want the keypad to control. The next will be the following unit code in sequence. For example: Say you have a 4 unit keypad and set the XPT dials to B-4. The keypad will control units codes 4, 5, 6, and, 7 in housecode B. If you just have a single button keypad for one unit, it will control B-4. You simply attach whatever keypad configuration that you need to the front of an XPT base transmitter. Keypads are available in either white or ivory to better match your decor.

To attach a keypad is easy, you slip the top tab of the keypad under the metal tab of the base transmitter, then push the bottom of the keypad all the way in so the keypad pins are inserted into the XPT base socket. Then put on any decorator style wall plate. You can mix or match keypads at any time as your requirements change. You can even wire in several XPT transmitter bases to set up multiple keypads to control all of your X10 modules from one wired-in location. Think of it as a mini-controller that's mounted in the wall.

Like a mini or maxi-controller, the XPT base transmitters generate their own X10 signals and put them directly onto the powerline. You don't need a transceiver. An XPT transmitter base and keypad combination does not directly control the electrical load, but rather sends out X10 signals to wall switch, wall outlet, lamp, appliance, and in-line modules to control them. Those modules do the actual load handling. The XPT is also a smart transmitter in that it automatically monitors the AC powerline for noise and other X10 signal activity and will not transmit until the line is clear.

  1. XPT In Wall transmitter Review

    Posted by Chris Swanberg 7 years ago

    The notion at first of an in wall switch that really does not directly switch anything seems a little odd, but with some imagination it really opens up possibilities. You just need to think a little outside the box. Example: I had a single back patio light with an interior switch inside. I wanted to put two separate lights on that circuit for patio lighting, and also a 3rd light that served as landscape lighting. BUT I wanted to be able to separately control each, from the location of the single switch. Here's how I solved the problem. In the conduit line I ran from the original light location, I put a conduit box large enough for two inline dimmable modules that directly control lights by X-10 line commands. In the higher mounted architectural light, I put a 3rd dimmer module in that box. I set the addresses sequentially (e.g. B7, B8 and B9) Now I "hot wired" the circuit into an always ON state so that any on-off control would come from the modules hidden in the boxes. Next I wired the switch into the old switch location black to black/white to white, so it is powered and on the powerline. Result... I can control all three lights independently, from the "old" single switch location. An added benefit is that I can also control them remotely via X-10 controllers and keypads. A great little device, used properly.
