{% hint style="info" %} FRX Pros configured for use in non-ALTA products (ie, Mōvi) need to
be reconfigured before they can be used in ALTA. Please contact Freefly for instructions to
reconfigure the radios. The symptom for mis-configured radios is that only one radio shows
a Green LED and rebinding does not reestablish communications. {% endhint %}
Datalogging
ALTA X provides comprehensive logging capabilities, which are enabled by default. In the
default configuration, logging starts when the aircraft is armed, and ends when the aircraft
is disarmed. These logs are stored on the onboard SD card, and can be downloaded to
provide information about the flight.
Downloading Datalogs
Logs are stored on the onboard SDcard. To download them, follow the following steps.
1. Ensure the ALTA X's battery is unplugged.
2.
Hold down the button labeled “MSC” on the expansion board while plugging in a USB-C
cable that is attached to a computer. Hold the MSC button for 5 seconds.
3.
The aircraft should enumerate as a USB drive on the host computer. This may take
another 10-15 seconds depending on the host PC.
4. Open the new USB drive in a file manager.
5. The “logs” subdirectory contains all the logs.
6.
In the logs directory, there are subdirectories labeled with a date. In each folder is a time
stamped file with a “.ulg” extension. These are the logs
7.
Download whichever logs are of interest. There may be some logs with very small file
sizes, less than 1MB. These are typically generated by arming and then immediately
disarming.
{% hint style="info" %} If the aircraft never acquired GPS, the aircraft may not have good
time information and may label the folder as “sess002” or equivalent. In this case, the
largest number is the most recent. {% endhint %}
