Unless I've overlooked something, the X-10 module that has the antenna, works with the wireless remote, and has an appliance module built in, is hardwired to address 1. If find this quite annoying and was wondering if it could be set to another address. I suspect if I take it apart and compare it to a conventional module, that I'll find the same chip in there, that the switches just ground or float a set of 4 pins, and that on the receiver module I could clip or unsolder them and pull them the other way to change the address. But I don't know. Has anyone been through this before? You could save me the trouble if the answer is that it doesn't work.
