Try something known as an RX-232 Expander. It takes traffic from one RS-232 port and spreads it out to 2 or more RS-232 ports.  If you have fast traffic, it will spoil your day if you try to divide that fast traffic port into 2 or more ports.  Some ports want to see fast traffic with minimum latency (delay). Ask Garmin if they make one or better yet, consult with one of their technicians to see if the Expander is compatible with their traffic flow.  I know GRT makes an Expander and works well with their traffic flow.



I'm still trying to figure out why RS-232 is being used in experimental airplane applications.  They should have gone with RS-422 a long time ago to avoid signal compatibility and integrity issues.
