I tried again to connect the nmea output of my ST50 repeater via the USB to RS422/485 item from sailoog's shop.
When I connect the NMEA ST50 output "signal" to R+, and "ground" to R-, then the Green LEDs starts blinking steadily at circa 1 Hz (which looks good, isn't it ?)
But when I connect the item to the RPI USB Hub, the blinking almost disappears , and though declared in the OP tabs (USB Manager and NMEA 0183) nothing appears in the inspector windows, but a time-out exception message !
Any assistance most welcome !
I also tried an RS232 to TTL adapter cascaded with an RS 232TTL to USB device, without any success...
