Paul1436215384 Posted January 5, 2011 Report Share Posted January 5, 2011 Hi I have two wheel speed sensors reading off VR sensors to my G4 Xtreme. I am in the process of purchasing a dedicated external data logger, and would like to know the following : When those 2 DI (DI#1 and DI#2 in my case) are outputted via the serial interface, do they get sent as sine waves, or are they converted to square waves? I am assuming the G4 converts the sine wave to square wave internally for it's processing, therefore I am hoping that a square wave would get output. Unfortunately I don't have an oscilloscope to test this, hence my question. Thanks Paul Quote Link to comment Share on other sites More sharing options...
Dtech Motorsport Posted January 5, 2011 Report Share Posted January 5, 2011 The data will be sent out as the converted value which would either be frequency or speed so data available will be the calibrated value for that input eg. 100kph What are you using for a data logger?

Paul1436215384 Posted January 6, 2011 Author Report Share Posted January 6, 2011 I want to use a Race Technology DL1, which will be connected to the G4 via the ECU interface. It requires that speed inputs be square wave. My car has VR wheel speed sensors, which is why I hoped that the G4 would convert the signal for me. So if I understand correctly, I can configure 2 DI's for ground speed and driven speed respectively, and the DL1 will receive a square wave signal from the G4? Nice. Thanks for the reply.

Dtech Motorsport Posted January 6, 2011 Report Share Posted January 6, 2011 that data will come straight from the data stream you will just need to configure the logger as necessary what country are you in? regards Dave [email protected] www.dtechmotorsport.com Quote Link to comment Share on other sites More sharing options...
Paul1436215384 Posted January 6, 2011 Author Report Share Posted January 6, 2011 OK, it should work fine then. The data logger will just be configured to display the correct speed, using the DI stream output. Thanks for the help. I am in South Africa.
