Bus Interface Module for pressure
(Sensor is sold separately)
This Bus Interface Module connects to a solid state pressure sensor. There are two power & data interface (I/O) ports on
the module. Either one can be connected to the gauge system or to another module, allowing several units to be daisy
chained together. Do not connect the I/O port to anything other than a Dakota Digital gauge or BIM. Do not mount the
module in the engine compartment; it should be mounted in interior of the vehicle.
Each unit connected to the bus needs a unique ID number assigned to it. The unit comes preset with an ID value that
should not conflict with any other BIM connected to your system. If needed the ID can be automatically reset to an
unused value. The factory default label is PSI, but this can be changed in the gauge setup.
Labels available for each input are:
PSI -
generic pressure input. This will display PSI x, Px, or PRESSURE CHx where x is a number from 1
– 8
corresponding to the module ID
number. ID’s over 8 will start over at 1.
FUEL -
fuel pressure input. This will display FUEL P, FP, or FUEL PRESSURE.
AIR -
air pressure input. This will display AIR P, AP, or AIR PRESSURE.
BOOST -
vacuum/boost input. This will display BOOST, BP, or VAC / BOOST.
NOS -
nitrous oxide pressure input. This will display NOS P, NP, or NOS PRESSURE.
Specs for each input are:

No warning will be active for NOS P if the pressure drops to zero due to the tank being removed.
High pressure spikes found in many diesel applications can drastically shorten the lifespan of
a sending unit. In order to protect the sensor from these damaging spikes, a snubber adaptor
should be added before the sensor. Due to the vehicle specific nature of these parts, a
pressure snubber should be secured from your favorite diesel parts supplier.
