Data loggers and plug-ins / SNIFF RFID reader output
December 23, 2014, 04:35:16 AM
Hi All,

I want to send the TCP output of an RFID reader to SQL database.  Initially I want to analyze the data received from the RFID reader.  I directed the TCP output of the RFID reader to a TCP port in the PC and analyzed through PORT PEEKER, it displays the TAG id sent by the RFID reader. While trying with Advanced TCP logger the output is junk characters?? 

output of PORT PEEKER

192.168.0.199 : 10020 TCP Data In Length 8 bytes
