Hi guys, i've got an optical encoder from an old ink printer. The model is Agilent h9731 ( datasheet http://pdf.datasheetcatalog.com/datasheet2/9/0pql04k9oru8uez14wx9h3d3657y.pdf )
I wired up the Vcc to 5v, GND to GND and ChanA and ChanB to the oscilloscope and everything works fine but the encoder gets warm which i suppose is not good. So ichecked the datasheet and i found out :
Load Capacitance CL 100 pF, 3.2 kΩ pull-up
The pullup resistor is between 5V and Vcc , and the capacitor in in parallel with Vcc and GND ?
