Modifying the X-10 JDS Time Commander Plus


These instructions are based on Hans Attersjö's Home page.  I have not attempted this modification and I accept no responsibility for the effects of anyone making these modifications.   You follow these instructions at your own risk.

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

Modification Steps

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 Time Commander Plus. Even mini controllers 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 buying a new EPROM from JDS technologies

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.

If you attempt these modifications, please let me know your results, and read the warning on the X-10 240 volt modifications  page.
