XTB-IIR TW523(?) Interface vs. XTB-232 (CM11A)
« on: October 03, 2015, 03:05:32 PM »
Jeff,

I've had an XTB-IIR for a while and per my usual it's uninstalled.  That is about to change.

I'm using the Activehome CM11A with XTension.  The last few months it has been unusable, giving "Unexpected response from CM11"

10/3/15 4:57:17 PM CM11: CM11: Unexpected response from the CM11

Throughout this now it won't control any X10 devices.
I even replaced the CM11 with one of the new ones now being manufactured and got the same errors.

I'm about to wander blindly unplugging and pulling breakers to find out if the "unexpected response" is due to noise.

I'm confused by the reference to the TW523.
The main question have is can I directly replace RJ11 link to the CM11 with the RJ11 on the XTB-IIR?

If I need to buy a XTB-232 I'll do that.

Advice?

I just verified that I can control the X10 devices with an X10 tabletop controller.
That means it's the Mac-CM11 part that is broke. I guess I need to try a new serial interface.

The TW523 protocol is a digitized version of the signal bursts sent over the powerline.  Devices like the discontinued Stargate, HomeVision, Ocelot, Elk M1, and the WGL transceivers use that protocol.

It was developed by X10 back before computers became a household item, and is not at all compatible with the serial or USB port on a computer.  The XTB-232 emulates the CM11A serial port interface.  Some folks are using that XTension.

Thanks, Jeff,

I discovered after replacing the USB-Serial cable that the problem was caused by an bad RJ11-DB9 Serial cable to the CM11.
I'll likely send you an order for a new DB9 serial cable (or two with an XTB-232.)

That's great that you found the problem.  The original CM11A cable is still available on eBay:
