Hello, i Am attempting to set up my 5v IMU up to my iqan system. i am using a 10" display and a Qs20 24V DC power supply. I keep getting an error value based on Vref if i have my sensor hooked up to the reference voltage. 

is there another way for me to power the sensor through the screen? 

could i program a Dout to output 5V constantly?

Hello Samuel.

Do you know how much power the sensor draws?

The VREF on the MD4 display has a maximum load of 50 mA.

Do you have a shared ground between the sensor and the display?

No, you can not program the DOUT to a specific voltage.

And the DOUT on the MD4 is a low side output, meaning you are grounding trough the display when the output is turned on.

So you do not get anything out from the DOUT.
