Hello, I have a multiplus with a USB Hub, with 2 USB to RS485 cables, one for the EM23 and the second for the ET112. From time to time the communication with the ET112 fails.
For the EM24 I use the original victron 1.8m cable.
For the ET112 a use a USB to TTL adapter fom FTDI and a TTL to 868MHz radio and on the ET112 side a RS485 to 868MHz converter, the radio device is configured for 9600 baud 8N1 fix.
This setu up works but from time to time the communication fails, I my question is:
- can a USB Hub without extra supply be used e.g. can the multiplus feed two loads with 120mA each.
- does the multiplus change the baudrate of the communication from other than the default 9k6 for ?
