Hi Tom,

I'm sorry, but your note below doesn't completely make sense to me.

Both the DB-9 port and the RJ45 port support RS-232 serial data
communication with external devices.

To what device(s) are you trying to connect the PowerFLARM Core?

The USB port is not a serial port. It is for connection to a USB flash
drive for firmware upgrades and flight log transfers.

Best Regards,

I'm confused about the RS232 feature with my PowerFlarm core.
The manual decribes the interface as RS232 but doesn't mention
the voltage levels. Is it the voltage levels called out in the
standard (-3 to -15, +3 to +15) or are these digital voltage
levels (0, 5) with the RS232 protocol? I see some pilots with
a DSub9/USB cable which will not give them the RS232 standard
voltage levels.
