DIN1 never change #1

Closed ptorrent closed 6 years ago

ptorrent commented 7 years ago

Hello,

I have a problem with the driver. Maybe I'm doing something wrong. I can not change the value of my digital input. I plugged a cable in the 24v output and connected it to DIN1. I do not see any changes ?

DI1..4: 0000 | CNT1: 00000 | CNT2: 65535 | AIN1: 0.000 | AIN2: 0.000 DI1..4: 0000 | CNT1: 00000 | CNT2: 65535 | AIN1: 0.000 | AIN2: 0.000 DI1..4: 0000 | CNT1: 00000 | CNT2: 65535 | AIN1: 0.000 | AIN2: 0.000

Thank you in advance for your answer

Hello,

the digital inputs on the Monarco HAT are isolated. It means they have separated COM potential from the power supply ground. In your case, you have to connect GND (13) and DIN-COM (15) terminals together. Are they connected?
