I am trying to update the firmware on my communications hub. I purchased the update cable from signature solar, it is labeled as an RS 232 cable which is apparently a slower cousin of RS 485. I plugged this cable into the USB port on my computer and the RS 485–3 inverter port on the hub. When I use BMS test software it will open the port however the get boot information fails and the update also fails. Has anyone had success with this update? My hub is version 1.6 and trying to update to 1.12.4. using BMS test software version 2.7.8.
