Encoder Wiring Quesiton

[evileye917]

OK... I was searching for how to hookup the Agilent quadrature encoder our team is using. I came across this site and searched but my questions weren't completely answered.

Our encoder has 4 wires: Phase A, B, Gnd, +5V. My question is how are they hooked on the RC? I get that the A and B are hooked separately. Are both hooked to the SIG slots? Secondly, are the Gnd and +5V inputs hooked to other Digital I/O pins or a set of the above?

Thanks for any help you can provide.

The A & B lines connect to two different SIG (inside) pins, either interrupts (1-6) or simple digital inputs (7 and above).
Gnd connects to the ground or "black" (outside) digital pin
+5v connects to the center pin for your power.

Typically we connect the A, +5v, and Gnd to one of the digital input sets and the B line to another.

Kevin Watson has an example program for encoders that also covers how to wire them. It's definetly worthwhile to check it out. http://kevin.org/frc/frc_encoder.zip. He has a bunch of other example programs at http://kevin.org/frc/.
