Optical Encoder Datasheet
I am using a CTS series 291 optical encoder for a project, I have attached the datasheet above this. The exact model I am using is the 291P1022 FX24ABB. So far I have hooked it up to my arduino board and keep track of the position, but I am not able to get the push button to work. The push button is connected with 2 pins instead of one like the other encoders I have used and I can not figure out how to use it. Any help would be appreciated, thank you.
