OBDII Scanner for Porsches

[lincolnb]

I just bought a 2000 Boxster S & recently had 2 occurences of the Check Engine Light (CEL) coming on. The first one happened right after getting emissions tests, where the tech removed the gas cap while the car was running. It took about a week & the light went out. I suspect that was due to the gas cap.

The light came on again about 2 weeks ago on a quick day trip down to Silver City. The light hasn't gone off this time & now I'm starting to suspect something more sinister may be at work here... Can anyone provide guidance on the model/type of OBDII meter & any connectors to help read the codes? Tried one from the local Checker without any luck & figured that it had to do with the adapter...

Thanks for any feedback.
