E127 wiring connection with Standard Horizon Gx2200

I would like to connect the Gx2200 using the 38400 Baud connections. I have the instructions to do that but I am confused by the Raymarine instructions since I also need some 4800 baud output for other equipment.

I know I have to set the E127 port 1 and the Gx2200 to 38400 Baud however I also need to have 4800 baud connections for my Auto pilot high speed connection, an additional radio and my EPIRB. Port 2 seems to be for input only. How do I get 4800 baud output?

would appreciate some help.

Thanks
