I have a D10A and an Avmap1000 (Lowrance) GPS in my airplane which I would like to connect together so that the GPS dat can be displayed on the HSI screen. I have the serial TX of the GPS connected to the Serial 1 RX of the D10A. However the GPS data is not displayed on the HSI screen. The Avmap1000's NMEA Output can include the GLL, GGA, APB, RMC, RMB, GSA and GSV sentences, and use baud rates from 1200 to 115200. Can these instruments be connected in this way? What settings should I use?
