Tach Threshold On/Off; D2D Jumper Settings - Viper 5301 Installation Manual

➤ 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 that it will work with these type
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 module.
