I'm working with CF-RU 5102 desktop reader to read a RFID card. I have downloaded vb.net SDK from http://www.chafon.com/productdetails.aspx?pid=384.

when i run the sdk im getting error "serial communication error".

SDK : CF-RU5102 UHFReader09 vb6.0_17051009420181.rar

Please try to add a code sample (take look at How to create a Minimal, Complete, and Verifiable example). The question probably will be closed as off-topic when it remains like it is now.
