I'm pretty stumped by this issue - particularly as I have started getting perfectly formed packets every time from the 1141+. The only thing that has changed in my house from the point where I was getting malformed packets is that my wife has taken down the Christmas decorations, though I have so fa...

Hi jrkalf,

Thanks for the info... so do you have the module installed in the ceiling with just a switched live behind your bi-stable switch, or is the module installed behind your switch?

I'm curious if anyone from the UK has had a go with this in 2-wire mode, with a wiring setup like this: http://www.x10-hk.com/store/manual/plcbus/wiring-plcbus-2267s-2w.pdf - I have quite a few of these PLCBus modules installed in the ceiling (or in the light fitting itself, which is very neat), whi...

The thread I was referring to is entitled "Plcbus 1141 ACK bug" but since my last round of testing, it is clear that the issue described is a different one (in that issue, the malformed packets were only received after a command was sent to an address that does not exist, and could be corr...

Interestingly, I seem to be getting some repetition in the responses. Here are some examples, all with an identical packet sent by the 1141+ (A2 On, 02 05 a9 01 22 00 00 03): > 0x06 > 0xa9 > 0x01 > 0x22 (") > 0x64 (d) > 0x00 > 0xac > 0x06 > 0xa9 > 0x22 (") > 0x00 > 0xa8 > 0x02 > 0x06 > 0xa...

Further to my last post, I have realised that my examples may not have been good ones - the checksums actually do cause the packets to sum to a multiple of 0x100 in both cases (both sums are equal to 1024). They are, however, 18 bytes long, and each segment of 9 bytes sums to 512, which makes me bel...

Hi Digit, Thanks for your reply - I did have a look at that thread, which was very helpful for determining why I wasn't getting a 0x03 byte at the end of my packets. But that isn't the problem - i know that a 9-byte packet with a checksum at the end that brings the sum of all the bytes to a multiple...

Hi All, My first post here, and I'm a beginner with reference to the PLCBus communication protocol, so please bear with me. I am attempting to roll a PLCBus controller using ruby (and thus the Ruby SerialPort gem), and I have had some success in being able to control my devices. Where I am having di...
