This Bus Interface Module has inputs for up to three digital air temperature sensors, SEN-15-1. Each input can be
configured individually. There are two interface 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 sensor connected to the bus needs a unique ID number assigned to it. This module has three inputs so it can
use one, two, or three ID numbers. Each of the three inputs can be assigned an ID from 1 – 16, or turned off. The
factory default ID numbers are 5, 6, and OFF for the three inputs respectively. The factory default labels are
OUTSIDE, INSIDE, and INTAKE respectively.
Labels available for each input are:
OUTSIDE -
outside temperature. This will display OUTSIDE, AT (air temp), or OUTSIDE AIR TEMP.
INSIDE -
inside temperature. This will display INSIDE, IN, or INSIDE AIR TEMP.
INTAKE -
engine intake temperature. This will display INTAKE, IT, or INTAKE AIR TEMP.
Specs for each input are:

Temperature unit will follow the unit set for the main water temp gauge.
Sensor Mounting notes:
Make sure the sensor probe can get adequate air flow. For outside temperature measurement, the front grill area or
above the front bumper may be a good location. It should be in a location that can get good air flow across it while the
vehicle is moving. When you are sitting still for a long period of time after driving the temperature reading may begin to
rise due to the engine heat radiating forward.
