Jamming I/O Setup
GPS jamming detection can be enabled to trigger output devices likes lamp or buzzer when the jamming is detected. The
data will be saved to flash memory during the period of jamming.
Either one or both of the device two output I/Os can be defined for jamming detection. Pull high/low or high/low pulse
output signaling settings are available.
The external power source is required for triggering output devices, or the device will detect jamming without warning.
When the output I/Os are assigned for jamming detection, any other command to trigger the output I/Os will be invalid
(no actions).
