AIO Micro Output Speed Questions

[Pat]

I think it’s like the ISO connector:

ISO 11786 7 pins Implement signal connection

Hi i want to build this connector in my old tractor to connect equipements like an APV. [iso11786] Official ISO11786 Data signals 5.1 Signal characteristics The signal characteristics for true and theoretical ground speed, PTO rotational speed and linkage are so specified as to be compatible with CMOS logic as defined in JEDEC1), powered from the tractor battery with a minimum voltage of 10 V. 5.2 True ground speed and theoretical ground speed 5.2.1 The signal shall be a square wave …

@Jakem0402

Could speed pulse output from AOG just be feed into Pin 1 below?

Yes, if you have a V4 board, you can plug the SPEED+ pin, it wont hurt the controller.
Maybe it will need a 2k pullup to work.

Follow this tread:

Speed Pulse Output to be ISO compatible

Speed pulse output at the AIO board should be according to the ISO standard in order to avoid issues when connecting different types of implements, or have to solder pullups or pulldown resistors. The ISO standard is higher than 6,3V and lower than 1,5V. Square pulse
