This is true.. the only thing I'd say is that not all IBUS messages are direct.. there is quite a lot of messages that get sent to GLO (Global), but the LCM doesn't listen out for those afaik
however.. the GapTech does run on the KBUS, rather than the IBUS, so if it's causing some sort of headache on that line, who knows? lol
Ah, I didn't realise the GapTech ran over K-Bus, I just assumed it was I-Bus because when mine was blocking the bus and sending out spurious packets I was getting a lot of warning lights going on/off randomly and AIUI, they're controlled by the Kombi (IKE) module which I always think of as an I-Bus module - I haven't looked at the bus info for a long time but but IIRC on some chassis the IKE is also the gateway between I & K busses so that would still make sense
I didn't mean the I-Bus messages are 'direct' (as in point-to-point), I said 'directed' as they have a receiver ID in the header - the broadcast (GLO) messages are just a special case as the modules accept anything with a broadcast value as the receiver ID as being addressed to them. Strangely enough I seem to recall that the I-Bus uses two different broadcast IDs 0x00 and 0xFF but I haven't got a clue what, if any, difference there is between them
Unfortunately, we're not going to the National but, if you don't get any joy with Steve's research, or find another guinea-pig that's attending, I can always mail you my Gaptech
