0-10V analog voltage output explanation:
When the signal input port is not connected, the output port gives 0V. The first time when we power on this module, we better calibrate it: find a 50% duty ratio signal, connect to DIN-, DIN+, the amplitude matches corresponding jumper. When frequency is at 1kHz ~ 3kHz, use a multi-meter to test AO, GND. The meter should be showing around 5.4V. We adjust the potentiometer on the converter module to make multi-meter shows about 5.4V. After this is done, we have calibrated and matched pulse signal with this converter module.  The module has a definition of 0.1V. Output current 10mA. If duty ratio is in opposite to voltage, we can select PWM output pin STEP LOW / ACTIVE for MACH3 software.
