I'm hooking up my 430 to my 240 audio panel and have a question for you experts out there. The wiring diagrams have me a bit confused. Its clear that the 430 Com 1 audio HI pin 7 connects to the 240 Com 1 audio HI pin 9. Also the 430 Com 1 audio LO pin 19 connect to the 240 Com 1 audio LO pin 10. It also shows the 430 Com 1 mic audio HI pin 6 connects to the 240 Com 1 mic audio out pin 11. The 430 com 1 mic key pin 4 connects to the 240 com 1 mic key out pin 12. The 430 com 1 mic audio LO pin is where i get confused as there is no corresponding connection shown to the GMA 240. I would like to assume that I connect it to the 240 pin 10 also but I'm just not sure. Can someone who has walked this path give me some enlightenment here.
