Re: Cresnet bus


 

Hi Chris,

Do you mean if the Y and Z have been crossed?

If you have two processors on the Cresnet, ONE of them will be on address 02 and the other MUST be on a higher address (in order to make it a slave). If they're both on 02, then they will BOTH try to take control of the Cresnet bus, and fight over the Y and Z lines. I'd be surprised if you'd see any Cresnet devices in such circumstances. At best, I'd expect very intermittent/corrupt responses from slave devices.

If one is a master and one is a slave, the slave will sit with its transceiver in high Z (i.e. listening to the bus) and you just won't see it if the Y and Z are the wrong way around.

If the master has Y and Z reversed, again, I think you're looking at a very quiet Cresnet bus as none of the devices will respond.

To be honest, I think off-site diagnosis is going to be inconclusive.

All the best,
Ol

So I have 2 questions.

First is - does anyone know if you can tell from offsite if 2
processors' cresnet buses have been crossed?

and second, what would the effects be if they were crossed?
