must cross a Critical threshold in order for the GPS information to be sent to
the AMM.
·
Accuracy Unit
: specifies the units to be used for the Critical Accuracy
Threshold field (see below). Selectable values are yard and meter. The
default is meter.
·
Critical Accuracy Threshold
: specifies the threshold of measurement
beyond which a critical accuracy threshold event will be generated.
Values must be greater than 0. The default is 5. Note that the number of
seconds specified in the Critical Accuracy Interval field (see below) must
have also elapsed before the event will be triggered.
·
Critical Accuracy Interval (secs)
: specifies the amount of time (in
seconds) after which a critical accuracy threshold event will be
generated. Values must be greater than 0. The default is 30. Note that the
threshold specified in the Critical Accuracy Threshold field (see above)
must have also been exceeded before the event will be triggered.
·
Critical SBAS Status Event Reporting
: when enabled, specifies that
SBAS (satellite based augmentation system) events will be reported to
the AMM.
·
Critical SBAS Interval (secs)
: the interval (in seconds) at which to
report SBAS events. Values must be > 0. The default is 30.
A.12 General Configuration Settings
A.12.1 Startup
•
AutoPower
: changes the start up behavior. When enabled, the oMG starts
automatically when power is applied. Otherwise, the RESET button must be
pressed to start the oMG.
•
Delay After Ignition On (secs)
: defines the number of seconds of wait time
before turning on the oMG’s power after the ignition is turned on.
A.12.2 Shutdown
•
High Voltage
: the upper voltage limit. Note that voltage readings are subject
to cable length and will always be slightly lower than the voltage measured at
the source.
•
Low Voltage
: the lowest voltage limit. This value is set to ensure that the
oMG shuts down to prevent further discharge of the vehicle battery.
Note: This is the “slow discharge” shutdown. When a vehicle cranks, the ignition system
should conform to SAE J537. If it does not and the voltage spikes down below the SAE
minimum the oMG will reboot, regardless of this setting. Also, voltage readings are subject
to cable length and will always be slightly lower than the voltage measured at the source.
•
Low Voltage Alarm Hysteresis
: if the oMG shuts down due to a low voltage
alarm, it will not restart again until the input voltage exceeds Low V
Low Voltage Alarm Hysteresis. The default Low Voltage value is 11v and the
default hysteresis value is 0.9. Therefore the unit will not restart until the
