Modbus mapping help
#24
This while painful experience happened after a system crash, then I lost the Modbus profile, settings and all that. I mean, currently really only have 4 x RS485 thermostats connected to the LM4, which I use to map to KNX so that I can control them from a HomeKit gateway.
If the profiles are good, then I might just need to test if the RS485 ports are funcitioning. I have already ordered a USB-RS485 connector, it's on the way.

Ah... I thought I need a profile to do any tests... Scan and Read. Sorry~
In that case, I am really out of ideas, this is more and more leading to a faulty 485 ports
