GRT Avionics

Hi Jeff,
A few additional questions about the data in the serial output stream:
1. I notice that the EIS has a "Serial In" line on Connector A. This is not hooked up in my aircraft, but I wonder if it is used for anything?
2. The data fields (ASPDH,ASPDL), (ALTH,ALTL), and ROCSGN imply that the EIS ...

Thank you, sir!

The EIS Log data can be saved to a spreadsheet format. When you use File, Save As in the EIS Log program, use the file name extension ".csv". The data will be in the same order as in the program.

My engine has one electronic ignition and one magneto. They are wired to the EIS RPM/N1 and RPM/N2 inputs, respectively. I have verified that both N1 and N2 data are recorded in the EIS data stream. Usually, the two data fields have the same number, but during start or other changes in RPM, the two ...
