Probably a Simple OC Question

Hi all,

I've decided to rebuild my 767 mcp interfacing all inputs and outputs to OC cards. I've gotten my displays to work, but when I hook up inputs, I run into problems. First of all, no matter what the input type, (switch, rotary, etc.) it makes the red LED on the USB Expansion light up, and the input number shows up in red in Controlador. Is this normal?

Second, when I hook up a rotary encoder, the inputs will show up in SIOC monitor, but they light up in sequence when I turn the knob. I.e. when turning it one direction, the following sequence will light up: 4, 4&3, 3, blank. What am I doing wrong?

For reference, I am using CTS288 encoders (288T232R161A2), 16 COM (4 pulse) 2-bit binary type. All of the inputs are being plugged into the J3 or J4 connectors.

Thanks in advance!

Steve

First of all i'm pretty sure that the usb expansion light is normal, im pretty sure that it means that it see's the connection. Im not quite sure about the rotary encoder though you might need to do some research on that one.

Hope this helped and if you have the time check out my problem.

Thanks

Hi Steve.

The sequence on those encoders seems right. Then should be like: off-off - on-off - on-on - off-on. Which seems like "4, 4&3, 3, blank."

On my OC Mastercard the red LED lights up when I connect my card and when ever an input is registered. Sounds much like the way our MasterCard behaves.

Cheers

Peter and Hey336,

Thanks for both of your answers! I've always used either arduino or third-party cards in the past for my rotary encoders and buttons, so I wasn't familiar with the manner in which the OC cards behave, but this solves my problem (which turned out not to be a problem at all.)
