Should work, best to test it first. Also, check to see if there is a
"ground" in the serial wiring diagram too. If so, you need to connect
them together as well, but that can be done permanently (not switched) I
would think.

A friend has two Volksloggers, primary and secondary. The
primary feeds data to his SN-10. The primary failed last
weekend and he wants a way to switch the secondary to the
SN-10 while in flight if it happens again.

I suggested a simple double pole double throw switch to
switch the TXD and RXD lines from the SN-10 between the
primary and secondary VL's. Has anyone done this? Any
problems?

Thanks.
