If your Camaro is a 95, the reason you cannot get your OBD2 to link up is because even though you, (well, we, (I love my 95 Camaro)lol) have a OBD2 type connector, the system is actually OBD1. Some call it OBD1.5, but ultimately it is known as an "ALDL" port to which GM transitioned to the OBD2 Standard in a confusing way. Using OBD2 Connectors on the remaining OBD1 cars before being fully OBD2 compliant on 1996 vehicles and above. Here is a link to where I purchased my cable to connect to the PCM and PC.
OBD1 16-pin OBD2-'style'-connector:

I recommend getting as familiar as you can so as to make sure to purchase the correct cable, (the one I linked to is the one that I bought for my 1995 Camaro that has an OBD2-style-connector but is in fact a OBD1 system. You can confirm this usually by the sticker under the hood, atop the radiator in front of the engine bay. I should say OBD1 compliant. After you receive the cable, (or while your waiting for it to arrive) research the various programs that will be used to read codes, etc. The ALDL site has all that info as well. If you have any other questions about that, feel free to ask. Hope this helped!
