ACTIVE HIGH:
When set to this state, a voltage above 4 volts (generally 12
Volts DC) on the given sensor input is interpreted by the
DVR to mean that the signal is activated, a voltage below 4
volts, (generally 0 Volts DC or Ground) is interpreted to
mean inactivated.
ACTIVE LOW:
When set to this state, a voltage below 4 volts (generally 0
Volts DC or Ground) on the given sensor input is
interpreted by the DVR to mean that the signal is activated,
a voltage above 4 volts, (generally 12 Volts DC) is
interpreted to mean inactivated.
The Active Low setting is very useful on certain types of vehicles and can
be used so that for the Brakes, for example, the Installers Mode screen says BR
when the brakes are being applied; as opposed to being there all the time until the
brakes are applied.
