Those are the settings and limit pages. There are a bunch of "Disable Pg#" settings, so you may not be able to tell them apart. Keep pushing the right button (Next) to go to the next setting, or hold down the right button to cycle through all settings and exit the settings menu.

"Cont" is the LCD ...

It seems like it could work with their P-lead voltage spike but other information says you need the Tach2. Here is what Ken told another customer a few months ago:

You will need the Tach2 module to get a tach signal from the SureFly SIM. Connect the SIM P Lead to the Tach2 module, then the 0-5V ...

For timing advance, a scale factor of 25 with offset zero, forwarded sensing, Integer follows their example: 2.5V would show as 25. If it can do fractions of a degree and you wanted a decimal point you would use a scale factor of 250 in Decimal mode to get 2.5V showing as 25.0.

The standard 100 amp settings (forward sensing with scale factor 164 and offset 313) would not include a decimal place, so you'd want to set up that Aux input for Integer mode. That would mean it was actually indicating 12 amps instead of 1.2.

It is updating with the full rate of the AHRS input, which is 15 times per second.

No, there are no HDG-to-VOR or HDG-to-GPS automatic intercept modes. The only HDG intercept modes we have are for the LOC/ILS, GPSV, and SAP approach modes.

The EIS 4000 has an OAT probe input on pin 22. It has to be the type of OAT probe that we make. Technically, you can connect one of our OAT probes to the Carb Temp input, but you would only do that if you needed to monitor an additional temperature. The EFIS will automatically recognize a sensor on ...

You can't use an EXT label for an SL30 or anything that's just a GPS or just a VOR/ILS receiver. It's used for GPS/VOR/ILS combo units with mode switching like the 480/430/650/etc. The "NAV EXT2 LABEL" setting is not used in your system. It sounds like everything is working correctly now.

Your 480 is NAV1. This is configured by the "ARINC VOR/ILS Inputs" setting. Your SL30 should be NAV2. Your SL30 should be configured as SL30-2 everywhere to tell every EFIS it's NAV2. The serial port and display link settings have SL30-1 and SL30-2 for that purpose. You should not have any EXT2 or ...

I got the DEMO files. Your 480 has an incorrect ARINC output setting so the EFIS can't see the mode or all the GPS data. One of your ARINC outputs is set to "ARINC 429" and that one needs to be "GAMA 429 NO FP". Don't change the VOR/ILS one, that one is working fine. You can check the received data ...
