6. Introduction CAEN UHF RFID Readers Communication Protocol Technical Information Manual CAEN3FID General Information This document describes the message format of the communication protocol used by the host and the reader in order to issuing commands and reply with responses The protocol is based on the Attribute Value Pair AVP schema and foresees a message header in order to identify the message scope The command set and the firmware architecture draw inspiration from the Reader Protocol 1 0 specification draft from EPCGlobal but at now this protocol is not fully compatible with the same last specifications Message fields are described left to right with the most significant byte on the left and the least on the right CAEN RFID Readers Communication Protocol Technical Information Manual CAENRFID Protocol Specification CAEN UHF RFID Readers Communication Protocol Technical Information Manual 3 CAENFID CAEN UHF RFID Reader protocol uses two logical communication channels one for synchronous commands and one for asynchronous notifications Command channel is mandatory and at now it is implemented on top of a TCP IP socket port 1000 and on RS232 while notification channels are implemented only with sockets All the messages commands responses and notifications are composed by a header and a body In all cases the body of the message is a list of attribute value pairs Responses always e
