Hi Jamie

 

I've been an RFID software/firmware specialist for the past 8 or 9 years....

Could you help answer a question for me?

I've got an proprietary access control system that I installed and manage for my company. It is from kerisys

I wanted to know if it would be possible to hook up one of the readers from the system (which uses a RS485 interface) to a netduino ?

how would I know what or how to program the interface to read from this reader.  I do not even know at what frequency the tags are - I suspect it's the longer range frequency.

I have successfully gotten my netduino to read tags from a uart/serial RFID reader (RDM630).

I have also tried the various examples above, and am also getting the ArgumentOutOfRangeException.  It's not just Gmail either, because I've tried with a local smtp email server that accepts Auth, plaintext, and none.

did u ever resolve this issue ?
