SPD OUT
This terminal can be used to supply a speed signal to auxiliary devices such as a cruise
control or radio volume adjustment. The output is scaled to the input speed signal coming into
the SPD SND terminal. It can be set to 2,000 PPM or 4,000 PPM.
***If you are using the bus speed signal option, with the output from a BIM module,
this output will NOT work.
SW2 (-) or Tach switch
The SW2 terminal is used for selecting the various RPM, engine, and performance
displays and also for entering the demonstration mode. The SW2 input is activated by a ground
connection. The push button switch supplied (or any normally open, momentary switch) is wired
by connecting one terminal to SW2 and the other terminal to a ground. When the button is
pressed and released, the tach/LCD2 message display will change. When the button is pressed
and held for a few seconds, any re-settable information displayed will be zeroed.
To enter DEMO mode, press and hold SW2 while turning the key on. The system will light
up and say
DAKOTA DIGITAL
on the message readouts; release the switch and the system will
stay in demo mode until the power is cycled off and back on without the switch held. All back
lights will be on in demo mode and the needles will sweep back and forth on the gauges.
SW1 (-) or Speed switch
The SW1 terminal is used for selecting the various speed, distance, and warning displays
and also for entering the setup menu. The SW1 input is activated by a ground connection. The
push button switch supplied (or any momentary normally open switch) is wired by connecting one
terminal to SW1 and the other terminal to a ground. When the button is pressed and released,
the speed/LCD1 message display will change. When the button is pressed and held for a few
seconds, any re-settable information displayed will be zeroed.
ADJ SND
The ADJ SND terminal is an optionally used input that allows you to have control over the
dimming brightness. By default, the system will turn on the back lights when the DIM terminal
has power, +12V, but this level is adjustable in the
Lighting
setup menu. Using the ADJ SND
terminal allows you to have a dash mounted control to vary the brightness while the headlights
are on. This requires Dakota Digital’s DIM-1 kit; a stock headlight rheostat will not work.
The DIM-1 has two wires, one connects to the ADJ SND terminal and the other connects
to ADJ - ground. The dash mounted dimmer will only vary the display brightness when the DIM
terminal has power, +12V.
ADJ –
This terminal provides a ground reference for the optionally installed DIM-1 for dash
mounted dimming control. One wire from the potentiometer will connect to the ADJ – terminal,
the other connects to the ADJ SND.
*This terminal should not be used for grounding other sensors or devices or damage to
the control box will occur. If not using a Dakota Digital DIM-1, this terminal should be left
open.
