I was under the assumption that the max masters setting referred to the physical number of devices on a network but as I sit here after wasting a day trying to get a bacnet network communicating it occurred to me that the max master setting may refer to the max MSTP address on the network which would explain why I can't discover some devices and have iffy comm. throughout my 5 networks. Can someone confirm or deny. I'm not looking to start another lon vs. bacnet debate.
