The binary protocol XP protocol provides information in high density. Its structure ensures a simple implementation. The transfer is done in single data frames. The interface for the binary protocol XP can either be a serial (RS232) interface or a TCP/IP or UDP interface.
SYMEO Local Positioning Radar System LPR-1DHP Product Documentation Byte stuffing is deactivated for the fixed frame protocol (compare chapter 8.3). 8.1.3 CRC The CRC-16-IBM with polynomial x16+x15+x2+1 is used for the CRC. The CRC is calculated over all data fields (TYPE and DATA), but not for the START and END field. The CRC-calculation is only applied to the original symbols. The appropriate calculation for coding must applied before byte stuffing.

SYMEO Local Positioning Radar System LPR-1DHP Product Documentation converter either the connection to a port on the LPR has to be initialized from the PC or the LPR unit is establishing a connection to a PC. If the connection is established, the PC has to read the data from the LPR in fixed data length (i.e. 89 bytes). The first byte is always the START-byte and the second byte is always the TYPE-byte. The relevance of the following data is depending on the data type.
