Radio Stack with IOcard

Recommended Posts

Hi everyone,Has anyone used IOcard from www.opencockpit.com, it seem's to be a good product and at great prices.If I want to build a radio stack (Cessna 172) I was wondering how many 7 segments display I would need to control, since the the "1" in all NAV and COM display are always on, I don't need to hook them on the IOcard. Since a IOcard can manage 16 display my count would be;8 digits controlled by IO card and one digits always showing "1" for NAV1, NAV2, COMM1 and COMM2.5 digits controlled by IO for the ADF4 digits controlled by IO for the transponder.For a total of 25 digits controlled by IO, I would have to buy 3 Display cards because it can managed 16 each.I'm I ok??Thanks for any help

Question: do you ever use com2 ? :(I leave that one out for now. And if I will install it I will hard wire it like you say with the 1's and the decimals. Dito with the last to 00 from the autopilot altitude.

You'll only need 2 cards as 2*16 is 32, which is more than 25 :(

I made a mistake, it's 8 digits for each com and nav so 8 * 4 = 32plus the ADF and transponder for a grand total of 41So I really need 3 cards I think.
