AS03 Protocol Bridge Board (RS422to232 and visa-versa)

SKU: QUA-0012

QK-AS03 Protocol Bridge enables the connection of Quark-elec (or other) NMEA 0183 RS422 products to older RS232 chart plotters or sensors (including older Garmin/Raymarine/Standard Horizon devices).

The AS03 Protocol Bridge Board converts NMEA 0183 RSS422 to RS232 and visa -versa.
