mesh network routing modes, where is documentation for Firmware 8075

clients have a mobile fleet 5 trailers. they operate in convoy talking to a supervisory vehicle with environmental data for live haul of animals. system is started during loading of trailers where they are all parked side by side. Having intermittent loss of random RS485 device ID.I have seen garbled and extended 485 data packets on end point software monitoring serial data.

Cant find documentation to explain network configuration options for Pro 900HP 200k firmware 8075. suspect mesh repeating in close proximity but unable to find relevant manuals or threads discussing the why and how to use optional modes for 900mhz network.

Thank for your time,
