Using the above set-up a vehicle can be enabled or disabled by clearing (enabled) or setting

(disabled) output 0 via PEG Scripts, Real-Time PEG Actions or SMS messages.

4.3.2 External vs. Internal Power Switch

This output allows the LMU to switch between power sources when certain conditions are

met (e.g. low power on the currently selected supply). If this output is set then the LMU will

use its internal battery as its power supply. If this output is cleared, the LMU will use the

external power supply.

By default, this output is cleared so the LMU will operate off external power.

4.3.3 Enable / Disable Battery Charging

This output allows the LMU to enable or disable the charging of its internal battery. If this

output is set then the LMU will stop charging the internal battery. If this output is cleared

the LMU will charge the internal battery.

By default, this output is cleared (i.e. battery charging enabled)

4.3.4 LED Outputs

On the LMU-1000™ the LED outputs mirror the behavior of the Comm and GPS Status

LEDs. These allow an installer to remote the LEDs from the LMU-1000™ so they can be

observed to verify an install.
