PCB-Mounted DIP Switch Chart and Function List
There is a Dipswitch mounted on the circuit board of the Engine Analyzer that can be
used to quickly configure the sensor for customized operation. The Dipswitch is
located at the back of the circuit board, and can be easily accessed by removing the
rear endplate of the enclosure. The function of each switch is defined in the
following table.
Switch Function Description
1 Sensor Type Select
On = NTK
Off = Bosch
2, 3, 4 NOT USED
5 Driveshaft Signal Type
On = 2-wire Magnetic Pickup
Off = 3-wire Hall-Effect/Square Wave
6 Not Used MUST BE OFF FOR PROPER OPERATION
7, 8 Not Used
Switch 1 – Sensor Type Select
For Engine Analyzer models with firmware version(s) 2.0.0 and higher, put this
switch in the ON position if you are using an NTK wideband sensor. Put this switch in
the OFF position if you are using a Bosch wideband sensor.
For Engine Analyzer models with firmware version 1.0.2 and higher, but less than
2.0.0, the sensor type selection is done on the configuration screen of the DataMap
software, and the dipswitch setting has no meaning.
Switches 2, 3, 4, – Not Used
The Functions of these switches will be determined in the future.
Switch 5 – Driveshaft Signal Type
In the ON position, the wideband controller will accept a magnetic pickup signal input
from a driveshaft speed sensor. This type of sensor is generally identifiable by its 2-
wire pickup. In the OFF position, the wideband controller will accept a hall-effect or
square wave signal input from a driveshaft speed sensor. This type of sensor is
generally identifiable by its 3-wire pickup.
Switches 6, 7 & 8 – Not Used
To be determined. These switches must be in the OFF position for the Engine
Analyzer to function properly.
