NMEA Tester

A universal tester with a resistive touch screen display is designed to check and display NMEA signals in text format transmitted via the RS422,485 bus.

 The tester can work both on reception (check incoming signals) and on transmission (generate the necessary NMEA signals and transmit them to the bus).

 The input bus is protected (suppressor) from high voltage (24v).

 The tester is powered by a 18650 lithium battery. The battery level is displayed on the main screen.  Charging is via a micro USB connector from 5v.
