Features 

 

 

Bi-directional WiFi, USB and NMEA 2000 

 

Combines inputs data from up to three NMEA 0183 input devices and one SeaTalk input 

 

Galvanically isolated NMEA 0183 and SeaTalk input ports. (also called opto-isolation. 
Galvanically isolation prevents unwanted currents between devices, preventing equipment 
damage and interference with radio signals 

 

Converts common SeaTalk

1

 data types to NMEA 0183 sentences 

 

NMEA 0183 to NMEA 2000 converter (converts common sentences to PGNs and visa-versa) 

 

WiFi: Ad-hoc mode allows up to 4 connections to the internal WiFi module simultaneously 

 

WiFi: Station mode allows for the connection of the A034 to your router/ access point for 
greater number of wireless users and WiFi range. 

 

WiFi: Standby option (disable WiFi) 

 

WiFi and USB input and output of combined data in NMEA 0183 sentence format 

 

WiFi and USB additionally output of NMEA 2000 network PGNs (in both 0183 sentences and 
PCDIN format) 

 

Compatible with Windows, Mac, Linux 

 

Compatible with Android and iOS via WiFi 

 

Filtering allows for overflow reduction and additional configuration. 

 

Routing reduces the risk of data over-flow.
