Analog input setup

The Analog Input window (Tools > Options > MP > Input/Output) is used to configure devices on the four analog inputs. Each tab corresponds to a pin:

Input 1

14

 

 

Input 2

7

 

 

Input 3

15

 

 

Input 4

8

 

 

To configure an analog sensor or gauge, select the tab that corresponds to the pin you are using and complete the fields as follows:

•Label: Enter a description of the sensor or gauge (Measured Voltage, Vehicle Speed, etc.), up to 20 characters long.

•Raw value: Shows the analog value from the input (read‐ only). The analog input has a 10‐bit (1024‐step) resolution, so the raw value range is between 0 and 1023.

•Zero scale: Enter the minimum value for the units you are reporting (used to convert the raw analog value of zero).

•Full scale: Enter the maximum value for the units you are reporting (used to convert the raw value of 1023).

•Current value: Shows the resulting converted value using the zero and full scales entered.

•Unit: Specify the units of the input (volts, km/h, etc.), up to 20 characters long.

Example

If you are measuring temperature, and the thermometer you have connected to the I/O connector measures between ‐30 (raw value 0) and +50 (raw value 1023) degrees Celsius, then your zero scale is -30.0and your full scale is 50.0. Your label could be “Temperature”, and units, “degrees C”.

The measurements are calculated for the 81‐degree range (between ‐30 and +50), which is divided into 1024 steps (0.0791 degrees per unit step). A reading of 25 degrees

(56 degrees above the minimum) would therefore show a raw value of 708 (56 degrees/0.0791 degrees per unit).
