Hi all,
i'm having trouble trying to solve a problem with my displays for the iocards

1) Transponder: displays 4321 on startup but when i try changing it only the last 2 digits move???

2) VS : starts up at 00500 but when i try changing it on changes in the range of -99 to 99 ???

The IAS & HDG work perfect

at this stage i'm not using sioc

thanks
Michael

Hi Michael. What PM offset are you using?

Bob,

Vspeed = $540C
Alt = $540A
Transponder = $0354

i'm also having trouble with the altitude readout.

Thanks
Michael

540A and 540C are writes not reads... Are you trying to write to those offsets or read them?

Hi Bob,
Found the problem, the last 2 digits have to be hardwired to 00 (no mention about this anywhere)
