Responder LE Model 5701 Security and Remote Start Installation ...

Tach threshold On/Off
In most cases, this jumper can be left in the OFF position. Some new vehicles
use less than 12 volts in their ignition systems. The unit may have trouble
learning the tach signal in these vehicles. Changing the jumper to the ON setting
changes the trigger threshold of the digital tach circuit so it will work
properly with these vehicles.
D2D Jumper settings
The security system has the ability to work with a compatible module through
the D2D lines. There are two settings: one for using an internal docking module,
(p/n 400N) or an external docking module. The factory setting is for the internal
docking module. When using an external module the jumper settings must be
changed.
