7.2RAW TCP/IP COMMAND & RESPONSE EXAMPLES

In RAW TCP/IP, RFID commands issued by the Host resemble Modbus TCP commands; however RAW TCP/IP commands require an additional two-byteheader (which includes 0xFF in the MSB, and 0x01 - the Node ID of the HS500E - in the LSB). These two bytes are inserted in front of the standard Modbus TCP command string. RAW TCP/IP response packets also contain the same additional two-byte header; 0xFF in the MSB and the 0x01 in the LSB. The HS500E handles all handshaking tasks.

In the following example, a 14-byte command has been issued to the HS500E (Node 01), instructing it to read 6 bytes from a tag within RF range starting at tag address 0x0001. A Timeout Value of two seconds has been set for the completion of the command.
