Serial output splitting.
Posted: Mon Feb 20, 2017 8:28 pm
This is a somewhat generic question, but this seems to be the best place to post. My hangar is finally warm enough to work again, with spring getting here.
I have a 430W that is current for ADS B out. I wired it to my 12" Hxr display with the proper ADSb+ format and it works fine, on the Hxr. I then outputted the serial out from the Hxr to my Trig 22 for GPS info. The format doesn't transfer, so my Trig doesn't see it as legal for an ADS B source. As I understand, I need a direct feed from the 430W to the Trig GPS input.
My question is, can I just split the current 430W serial out feed, and send a wire to the Trig 22 as well as the Hxr? That is, can the 430W serial output drive two inputs? I really would prefer they would be separate, but the 430W wiring at the back of the mounting tray is very busy, and somewhat fixed, so I would prefer not to get into that plug if possible. The Hxr plug with the serial data is readily assessable, so a splice there and then routing a serial wire back to the Trig 22 would be much simpler. The 430W serial feed is data and not a load, so it would seem that it should work, but advice would be appreciated.
Thanks in advance
