The good news is that we are making a software change to enable the EFIS serial port to receive aviation and transmit ICARUS altitude data.
EFIS Serial Ports:
#1 RXD Aviation <- GTN650
TXD ICARUS -> GTN650 + GTX330
#2 VP-X
#3 SL30
#4 ARINC Module
Then connect your 330 to the 650 and use it to display traffic.
