In 8.02-beta8 you can now use MORE, ENGINE (or just ENGINE from the ENG/MAP page) to get SCROLL and SCALE knobs for the time history. The upper right corner of the history will show a negative time offset for the graph ending on the right side as you scroll back. The bottom center changes to show ...

Yes, the warning light output simply pulls to ground when active. You can put anything you want there up to 0.11 Amps. A simple LED would need a series resistor to limit the current through the LED. Some LEDs made for panels have the series resistor integrated. The parallel resistor prevents the LED ...

The HXr has a warning light output that blinks when an alarm is active, or lights solid when all alarms are acknowledged but there's still an active condition. Active alarms have to be acknowledged through the ACK button on the EFIS. We don't have a remote ACK function although that could be added ...

2. You always want to update the Safe-Fly to version 4. The EFIS and Safe-Fly software doesn't change the altitude function and doesn't require any echo changes. We only made one change for altitude in that if the altitude input fails, the Safe-Fly will stop sending altitude. The main change for the ...

This means the AHRS is not receiving data from the magnetometer and the system always expects the AHRS to have a magnetometer connected. The Adaptive AHRS has a magnetometer power output, ground, and a serial input for the digital magnetometer. See pins 22, 14, and 8 on the AHRS connector and 5, 1 ...

The side doesn't matter. The direction of rotation is configured in the EFIS menu and you will test and set that as part of the setup procedure.

We don't have our own capstan instructions. The TruTrak, xCruze, and Dynon servos generally mount the same way so you can use any examples and ...

The GNC255 didn't have ARINC input and I haven't seen the 215 install manual. If it doesn't have ARINC input, the only way to control OBS from the EFIS is through RS232. If it has ARINC input, it may work, but our ARINC output sends the same course select to everything based on what NAV MODE the ...

A beta update with the GTR/GNC protocols is also available for the Mini but just hasn't been posted to the web site yet.

We usually use the RS232 interfaces when we can although the ARINC interface is good if you don't care about frequency transfer or anything besides VOR and ILS display. The GNC ...

Yes, the GNC215 has a similar RS232 interface to the SL30 and it is compatible with the SL30 format for frequency input. Our beta software update supports the newer Garmin GNC RS232 protocol. I have heard of customers using the ARINC 429 interface of GNC2XX models for the VOR/ILS display if they ...

We had some customers who wanted to manually limit what alarms are enabled during special flight operations. When this button is set to F/O-PRS, then only Oil Pressure and Fuel Pressure alarms are enabled and all other alarms are disabled.
