Così a occhio stai cercando di inviare dati al multiplexere in formato rs232 anziché rs422 ...

Ho trovato questo:

"FAQ – How to connect NMEA0183 RS422 to older RS232 devices.
This product uses the NMEA 0183-RS422 protocol (differential signal), however some older chart plotters or instruments may use the older NMEA-RS232 protocol (single-ended signal).

To ensure A031 compatibility with any older NMEA0183 device, check if your device uses NMEA0183 RS422 or RS232

NMEA0183 RS422 devices’ wiring is compatible ‘out of the box’
NMEA0183 RS232 will require a Protocol Bridge (AS03) to connect your wiring
.

Connecting the A031 to an older (RS232) instrument or chartplotter is not a problem, simply order the QK-AS03 Protocol Bridge. Our QK-AS03 Protocol Bridge connects NMEA-RS232 wiring to MNEA0183-RS422 and vice versa, using a simple ‘Plug ‘n’ Play’ connection, with no setup or configuration needed."
