Spd Out; Sw2 (-) Or Tach Switch; Sw1 (-) Or Speed Switch; Adj Snd - Dakota Digital 3 Series Installation And Operation Manual

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 2000 PPM or 4000 PPM.
***If you are using the BIM-01-1 bus speed signal option this output will NOT work.

SW2 (-) or Tach Switch

The SW2 terminal is used for selecting the various rpm, engine, and warning displays
and also for entering the demonstration mode. The SW2 input is activated by a ground
connection. The push button switch supplied (or any momentary, normally open switch) is wired
by connecting one wire to SW2 and the other wire to a ground. When the button is pressed and
released, the tach message display will change. When the button is pressed and held for a few
seconds, any re-settable information displayed will be zeroed. On systems with two message
displays, the one below the tach is dedicated to rpm/warn messages. On systems with one
message display the speed/performance and rpm/warn messages will use the same display.
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.

SW1 (-) or Speed Switch

The SW1 terminal is used for selecting the various speed, distance, and performance
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 wire to SW1 and the other wire to a ground. When the button is pressed and
released, the speed message display will change. When the button is pressed and held for a
few seconds, any re-settable information displayed will be zeroed. On systems with two
message displays, the one below the speed is dedicated to speed/performance messages. On
systems with one message display the speed/performance and rpm/warn messages will use the
same display.

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 dim to approximately half brightness when the
DIM terminal has power, +12V, but this level is adjustable in the NIGHT 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 a WHITE/BLUE wire and a BLACK wire. Connect the WHITE/BLUE to the
ADJ SND terminal and the BLACK 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. The BLACK wire will connect to the ADJ – terminal, the
WHITE/BLUE connects to the ADJ SND.
*This terminal should not be used for grounding any other sensors or devices as damage
to the control box will occur. If not using a Dakota Digital DIM-1, this terminal should be
left open.
