5.1 Reader to Host Protocols
5.1.1 StxNG
StxNG is the protocol used by the XC-RF300 reader to communicate with the
host system. Upon start up, the XC-RF300 reader starts listening for incoming
frames over Primary and Secondary TCP ports (default ports are ports 4000 and
4001. Only one connection per port is accepted).
After a valid frame is received from one of the interfaces, the corresponding
command is executed and a reply is sent back to the host.
Below is a short description of the “command” and “response” frame format.
Host to reader frame (command):
<SOF> <Address> <Command ID> <Nb Data> <Data> <Checksum>
Reader to host frame (response):
<SOF> <Address> <Error Code> <Nb Data> <Data> <Checksum>
