Document type: User's Manual (MUT) Title: CAEN UHF RFID Readers Communication Protocol Revision date: 02/04/2008 Revision: 5 1. Introduction 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.

Document type: User's Manual (MUT) Title: CAEN UHF RFID Readers Communication Protocol Revision date: 02/04/2008 Revision: 5 2. Protocol specification CAEN RFID 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.
