Dear Sirs,
We performed already several installations of EFIS D10A, EDC and OAT (type2). However a problem arose, now - D10A display shows: " OAT NOT FOUND" and "EDC NOT FOUND" (Remote compass not found). EFIS has the latest software (2.12) version. OAT probe is type 2 and this type is set in EFIS.
The installation of EFIS, EDC and OAT is exactly the same as we did already several times on our aircraft. We checked OAT probe - OK and all wiring - OK.
So we connected another EFIS D10A unit (having older software version 2.11) an it was OK - i.e. Compass and OAT were found immediately and all worked correctly. With the same settings.
It means the problem is probably in the EFIS unit (2.12.)?
We tried to update both this "wrong" Efis unit and EDC software to be sure that there is the same software version (2.12.). However this is impossible because EDC is not found in the unit so EDC software update is not possible through the unit.
We tried to replace 2.12 version in the unit by older 2.11 version, which was installed in that unit with which the EDC (and OAT) communicated correctly. This is impossible. A warning message announced , that EFIS S/N will be changed by this operation (????), we decided to risk it, but after clicking YES, another window box appeared showing that this is impossible (to replace new software version by an older one).
What do you advise us? Thank you very much for your support.
Sincerely
