feature descriptions
1 IGNITION CONTROLLED DOOR LOCKS ON/OFF:
When turned on, the doors will lock three seconds after the
ignition is turned on and unlock when the ignition is turned off.
2 DOOR LOCK PULSE DURATION:
Some European vehicles, such as Mercedes-Benz and Audi, require longer lock
and unlock pulses to operate the vacuum pump. Programming the system to provide 3.5 second pulses will
accommodate door lock interface in these vehicles. The default setting is 0.8 second door lock pulses. See
Mercedes-Benz and Audi - 1985 and Newer (Type E Door Locks section)
diagram.
3 DOUBLE PULSE UNLOCK OFF/ON:
Some vehicles require two pulses on a single wire to unlock the doors. When
the double pulse unlock feature is turned on, the H2/E BLUE/BLACK wire will supply two negative pulses instead
of a single pulse. This makes it possible to directly interface with double pulse vehicles without any extra parts.
4 SECURITY FEATURES ON/OFF:
In the ON setting, the unit will trigger an ignition panic sequence, and the
H1/1 ORANGE ground-when-armed output will remain active when the ignition key is turned on. In the OFF
setting, the ground-when-armed output and the ignition panic sequence will be inactive.
5 CODE HOPPING
™
ON/OFF:
This system features Code Hopping
™
as an option. Code Hopping
™
is a feature that
uses a mathematical formula to change the system’s code each time the transmitter and receiver communicate.
This makes the group of bits or "word" from the transmitter very long. The longer the word is, the easier it is to
block its transmission to the unit. Disabling the Code Hopping
™
feature lets the receiver ignore the Code Hopping
™
part of the transmitted word. As a result, the unit may have better range with Code Hopping
™
off.
