Digital inputs.

MaxxECU has digital inputs (DIN x) that can be used to trigger certain Digital input functions.

Note: User CAN inputs, AIN x can also be used to trigger digital input functions.

 

 

Digital Input (DIN x)

clip0023

 

function

Specifies the digital input function to be triggered when the DIN x input gets active.

 

active level

Activate the digital input function when input gets high or low.

 

pullup

Use internal pullup (+5V), to be able to trigger the input when connected to GND.

Note: if you do not enable the Pullup on this input, you can either input +5V or +12V to trigger it.

Note: Internal pullup on MaxxECU DINx (digital input) is 2k5 ohm).

 

input type

Digital or VR input.

Note: Not all MaxxECUs has this option, depending on MaxxECU hardware revision.

Note: DIN x inputs will trigger on 0.15V when set to VR.

 

 

Using AIN (temperature) as digital input

clip0215

In the above example a simple switch is connected between GND and AIN 1 to close the circuit and activates

the secondary boost target in boost control.

 

wiring-digital_input_to_gnd

Example wiring to ground a DIN x (with pullup activated) or AIN (temperature) (since these AIN (temp) have built-in pullup they can be triggered when grounded.

 

 

 

Using AIN (0-5V) as digital input

clip1234

You can also use an AIN (0-5V) to trigger a digital input by wiring a +5V or +12V source through a switch to a AIN (0-5V) input.

 

clip1236

In the above example where we set AIN 4 active level to active high, the boost target changes to boost target 2.

 

clip1235

Example wiring to trigger a digital input function on a AIN (0-5V) input.

 

 

How to make digital input 3 (DIN 3) visible?

MaxxECU V1/RACE and PRO (REV4+) has the ability to use GPO 7 as digital input 3 (DIN 3).

 

clip0056

GPO 7 used as digital input 3 (DIN 3) in the above example in Output --> Output config.

 

 

clip0057

In Inputs --> Digital inputs, DIN 3 is now available for usage in MaxxECU.
