3.3.1 Three-Axis accelerometer input
the LMU-3030™ supports an internal 3 Axis Precision Accelerometer as one of its discreet inputs. When
the LMU is moved in any direction, the associated input will be in the High state. If the LMU’s
accelerometer does not detect motion, then the input will be in the Low state. No external connections are
required for this functionality to be operational.
3.3.2 Status LEDs
The LMU-3030™ is equipped with three Status LEDs, one for GPS and one for COMM (wireless
network status), and one for VBUS. The LEDs use the following blink patterns to indicate service:
