The NL2’s sole function is to communicate speed data from the GPS Receiver
to the existing speedometer. The NL2 will in NO-WAY interfere or meddle with
normal MDC/MMDC computer functions. The computer data targeted for the
NL2’s speedometer is now ignored, and GPS speed is injected in its stead.

The NL2 will flash or blink the Speedo’s backlight to convey its state, intent,
or warning. To witness the flashing, the dash lights must be ON.
This is by design! For under normal conditions visual feedback from the NL2
becomes routine and unnecessary. Thus, the user has ability to enable/disable
these visible cues by turning the dash lights On or Off. Upon power-up, the
NL2 waits 2 seconds for the power to settle.

Visible Cues:

· No Flash or blinking: the NL2 is operating normal.

· Continuous Flash; ON for one second, OFF for one second:

    the NL2 is waiting for a satellite fix from a 1Hz GPS Receiver.

· Continuous Flash; ON for ½ second, OFF for a ½ second:

    the NL2 is waiting for a satellite fix from a 5Hz GPS Receiver.

The installation of the NL2 is a snap. Actually it’s a snap, snap, snap, and in. This is a retro-fit.
The NL2’s power and signal connectors are inserted in-line between the existing MMDC wire
harness and the speedometer. Wire stripping and/or splicing are NOT required.
