I recently bought this antenna (http://store.linkspr...8000-6c-epc-g2/). The software is working fine but I wasn't able to communicate with the antenna by RS232 with the protocol described in the documentation (https://s3.amazonaws.com/linksprite/RFID/integrated+reader/Communication+Protocol+of+LinkSprite+Long+Range+RFID+reader+.pdf).
After sniffing the packets on the COM port, I noticed that the request to read a RFID tag is 04 00 01 db 4b.
Is the documentation out of date? Where could I get the protocol for this RFID antenna?
