AIS Output from VHF to Axiom 9

[randytank]

I have a Standard Horizon GX2200 VHF/AIS that used to connect for AIS output only to my C80 and worked like a champ. The C80 is replaced by Axiom 9 and I need to get AIS data out from GX2200 and into Axiom 9. I do NOT need GPS input from Axiom to VHF, it's already built in. I've seen reference to Actisense NGW-1-ISO-AIS in forum but this is a $190 item and still needs a cable to the SeaTalkng backbone. Is there a more simple (i.e. cheaper) way? In addition to Axiom I have Quantum wireless radar and Evolution Wheel Autopilot.

BTW the Evolution Wheel pilot is the cat's meow. So much better than old X5 it replaced.
