The JG-LS provides support for specialized hardware features through extended AT
commands. The features supported include the following.
GPS
GPS location functionality is provided by the device GPS receiver. NMEA GPS
records can be extracted in real time from the unit via the UART connection using
special debug commands that are outside the scope of this document.
GPIO
Two general purpose GPIO and two additional multiplexed IO’s are presented to the
external environment on the main connector. They are capable of providing system
interrupts to generate a report or drive logic levels to external devices. These lines are
3.3V logic level and are 16V tolerant. The multiplexed IO’s are typically configured as
Ignition, Relay and Tamper.
LED’s
Three LED status indicators are provided to verify correct installation and operation.
The status LEDs are color coded and directly convey the status of the cellular and
GPS subsystems, as well as the power input; described in the table below. Their valid
operation also indicates operational status and power.
