It looks like this device converts X10 and PLCBUS Rf to PLCBUS powerline signals:
PLCBUS-T4023UK PLCBUS Encrypted RF Transceiverhttp://www.futurehomes.com.sg/PLCBUSPage.htm
...but I'm not 100% sure. Anyone know for sure?
I have a load of X10 rf switches and sensors (EU and US frequencies) which I would need to interface into LMCE with low latency to then control PLCBUS kit.
That transceiver looks like it receives the ENCRYPTED X10 messages.. like the ones from alarm sensors..
I think you'll probably have more luck with the PLCBUS-4808 X10/PLCBUS Transfer Interface on the same page.
That will act as a 'bridge' between X10 and PLCBUS. If you need to receive RF X10, then simply plug in a X10 RF receiver. (I'm sure you have one of those around). That will take the RF X10 and put it on the powerline, which will then be converted by the PLCBUS-4808 X10/PLCBUS Transfer Interface.
