The EarthX batteries provide a discrete output for each pulse, which is a ground signal (active low). However, EarthX batteries 100 series, such as the ETX 900, only have three indications - slow flashing (five seconds on, five seconds off), short flashing 2 seconds on, 2 seconds off) or on solid.
If you have it connected to a discrete input, then the fault indication on the EFIS should come on or off and repeat until the fault clears per the table.
To understand the fault, you need to compare battery voltage against slow, short flashing or on solid.
But either way, it's just a discrete input and should work as if it were pulsing an LED light.
I've tested this on my G3X and it indicates correctly. BTW, there is a fault LED on the battery itself, so if you're testing, you can compare what the battery LED is indicating vs the EFIS.
The above quote is from an older post in the RV-10 subforum.
Does the G3X have the capability for the discrete to be programmed to differentiate the three EarthX fault flash sequences so the message displayed on the EFIS can be specific to the fault indicated? I searched the G3X installation manual but I couldn't find anything.
If not, I've got my first request for the Garmin G3X Touch Feature Wish List thread.
