This is not a X10 module but I mention it because it is an interesting device. It is BTW, identical to the Homebase system but I believe there are some differences in the software they are currently delivering.

Modify the TW523 as mentioned elsewhere in these texts. Note that the three phase transmit would still be set for 60Hz. If you have three phase, I think that it is better to use a three phase active repeater and disable this feature on the Timecommander Plus. Even minicontrollers and other transmitting devices would in this case work correctly. This feature is stored in the firmware and can be changed between 50 and 60Hz by bying a new EPROM from JDS technoligies

Replace the wall mounted power supply with a 220V (or 240V) unregulated type, delivering a nominal DC voltage of 12V and at least 400mA. It is unregulated so the idle output voltage is around 16V DC. The connector uses negative in the middle and positive on the outside.
