KRT2 Radio
The connection to a radio of the type KRT2, or another model if the navigation device (e.g. XCSoar) has a driver
for it, can be established serially via rear interfaces ttyS7 or ttyS9. The baud rate should be set to
9600
baud. To do
this, make the connection from the XCTouchNav’s pin 3 and 4 to the corresponding serial RX/TX of the KRT2, it
is best to solder it there to the existing KRT2 Sub-D connector. It is important to wire together always RX to TX
and TX to RX as follows:
XCTouchNav 3 (TX) <-> 13 KRT2 (RX)
XCTouchNav 4 (RX) <-> 2 KRT2
(TX Remote)
XCTouchNav 1 (GND) <-> 1 KRT2
(GND)
