GMX 200 Safety Monitor Codes
The GMX 200 is designed to detect anomalies and unexpected operational
and data events. When an anomaly or event occurs, the unit assumes the situ-
ation is unrecoverable and continued unit operation is ill-advisable. Regardless
of the code, neither the unit nor operator has enough information to identify the
source and resolve the problem. To avoid the possibility of displaying mislead-
ing data, the unit reboots itself to restore normal operations.
When an event occurs, the unit identifies the section of the software where
the problem was detected. A code is displayed on the error screen before the re-
boot and in the MSG function after the reboot. Codes are organized by subsys-
tem and functional block. See the table below for the list of codes. Error codes
include four digits. The first two identify the function or software section that
detected the error. The last two digits indicate a specific line or software instruc-
tion. The error code is an indication where the error was detected. However, in
most cases it is not where the error occurred.
If the error code condition clears and does not return after resetting the
unit, it can be assumed that the condition causing the code was temporary and
the unit will continue to function properly. If the condition causing the event
persists, the unit will detect the event and issue another reboot along with a
code, typically the same code. This will continue until the unit is turned off or
the condition causing the event is resolved.
Repeated occurrences of the same code indicate there may be a problem
with the installation, with a sensor providing data to the GMX 200, or within
the GMX 200. This situation should be analyzed in order to determine the
root cause of the problem. Should a code be displayed twice within a short
amount of time, please record the four-digit code if practical along with any
other symptoms or information, and report the event to your Garmin technical
support representative for further analysis. The GMX 200 also records log files
on the SD card. A copy of these files should also be provided to Garmin to help
investigate the problem.
Operational Response
Codes are not indicators that provide specific operational guidance (i.e., go
or no-go). There is no specific action to be taken by the flight crew based on the
displayed code. Codes are an indication that the unit may have received unex-
pected data, had a problem processing the received data, or other difficulty.
The following are recommended actions based on the current situation:
Pre-Flight and Post-Flight
If a code appears, the pilot should let the unit reboot. If the problem does
not reappear, the operation may proceed. If the code continues to appear mul-
tiple times, the pilot should have the problem investigated by a mechanic. Re-
peated problems must be reported to Garmin technical support representative
along with the code number and logfile(s).
During Flight
If a code appears, the pilot should let the unit reboot. If the problem does
not reappear, the flight may continue. If the code continues to appear multiple
times, the flight may continue at the pilot’s discretion. The pilot has the option
to turn the unit off. Repeated problems must be reported to Garmin technical
support representative along with the code number and logfile(s).
