INTRODUCTION - CAEN UHF RFID Readers Communication Protocol 5 1 INTRODUCTION 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.

PROTOCOL SPECIFICATION - CAEN UHF RFID Readers Communication Protocol 6 2 PROTOCOL SPECIFICATION Introduction 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 echo the Command AVP sent by the host. All the packets for the control and notification channel share a common header format: 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-------------------------------+------------------------------+ | FIXED | Message ID | +-------------------------------+------------------------------+ | Vendor ID | +-------------------------------+------------------------------+ | Length | +-------------------------------+ FIXED: Must be 0x8001 for commands and 0x0001 for responses. Message ID: Id of the message. It is a sequence number used to map requests to its responses: a request and its corresponding response have the same message ID (the id is local to the channel). Vendor ID: Must be 21336: the IANA “SMI Network Management Private Enterprise Code” assigned to CAEN SpA. Length: Encodes the length of the message (in bytes) including the header. The header is followed by a list of AVPs the number of which depends on the command. Each AVP have the following format: 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-------------------------------+------------------------------+ | RESERVED | Length | +-------------------------------+------------------------------+ | Attribute Type | Attribute Value ……… | +-------------------------------+------------------------------+ | ………[ until length is reached ]……… | +--------------------------------------------------------------+ RESERVED: The first 16 bits are reserved for future extensions. All reserved bits must be set to 0 on outgoing messages and ignored on incoming messages. Length: Encodes the length of the AVP packet including the length and the reserved fields. Attribute type: A 2 byte code identifying the attribute type. Attribute value: The actual attribute value according to the type. It follows immediately after the Attribute Type field and runs for the remaining bytes indicated in the Length (i.e. Length minus 6 bytes of header).

PROTOCOL SPECIFICATION - CAEN UHF RFID Readers Communication Protocol 11 Command codes Note: Some commands have been renamed to align the nomenclature in this manual and in the CAEN RFID API Reference Manual. See § Tab. 2.4: Renamed Commands Table pag. 21 to know the equivalence between old and new name of the renamed commands. Note: Some commands have optional parameters. See § Tab. 2.3: Commands with Optional Parameters Table pag. 20 to know the CAEN RFID readers that support them. For the compliance of the command codes with the obsolete readers, please refer to the previous revisions of the manual that can be downloaded in the Manuals and Documents area of the CAEN RFID web site.

SourceNameOut: [out] the name of the source used. ReadPointName: [out] the name of the readpoint. TimeStamp: [out] the time at which the tags are detected. TagIDLen: [out] the ID length of the tags detected. ListOfIDs: [out] the list of Ids detected from the source. ResultCode: [out] the result code.

PROTOCOL SPECIFICATION - CAEN UHF RFID Readers Communication Protocol 12 Code Description Comp. 0x13 InventoryTag: permits to get all the tag’s Ids that are under the RF field of the selected source. Parameters: SourceNameIn: [in] the name of the source to use (optional) Bank: [in] the number of the bank to use (optional). Length: [in] Filter Mask Length (optional). TagID: [in] the Filter Mask Value (optional). TagAddress: [in] Filter Mask Start Address (optional) Bitmask: [in] Inventory Flags. When set to 1 for each tag detected the RSSI value is returned. Default value 0. (Optional). Flags: (optional). Bit0: RSSI: a 1 value indicates the reader will transmit the RSSI (Return Signal Strength Indicator) in the response. Bit1: FRAMED:a 1 value indicates that the tag's data will be transmitted by the reader to the PC as soon as the tag is detected, a 0 value means that all the tags detected are buffered in the reader and trasmitted all together at the end of the inventory cycle Bit2: CONTINUOS: a 1 value indicates that the inventory cycle is repeated by the reader depending on the SetReadCycle setting value, a 0 value means that only one inventory cycle will be performed. If the continuous mode is selected a 0 value in the ReadCycle setting will instruct the reader to repeat the inventory cycle until an InventoryAbort method is invoked, a value X different from 0 means that the inventory cycle will be performed X times by the reader. Bit3: Compact data: a 1 value indicates that only the EPC of the tag will be returned by the reader, a 0 value indicates that the complete data will be returned. In case that the compact option is enabled all the other data will be populated by this library with fakes values.

ASYNCHRONOUS NOTIFICATION - CAEN UHF RFID Readers Communication Protocol 22 3 ASYNCHRONOUS NOTIFICATION The notification channels are implemented only with sockets. All the messages notifications are composed by a header and a body. In all cases the body of the message is a list of attribute-value pairs. The first AVP of the body is fixed and called NotifyMessage. All the packets for notification channel share the same header format of other packet as described at § 3. The first AVP (NotifyMessage) is followed by a list of AVPs, the number of which depends on how many tags should be notified. Each AVP has the same format of the AVP described in § 3. The NotifyMessage has the following fixed format: 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-------------------------------+------------------------------+ | RESERVED | 8 | +-------------------------------+------------------------------+ | CommandName | ReportBuffer | +-------------------------------+------------------------------+ After the NotifyMessage AVP we can receive: a) a list of AVPs (as described in table 3) followed by an AVP with ‘Attribute Type’ ResultCode b) a single AVP called KillMessage with the following fixed format: 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-------------------------------+------------------------------+ | RESERVED | 8 | +-------------------------------+------------------------------+ | KillCommand | KillCommand | +-------------------------------+------------------------------+ Description TimeStamp: the timestamp of the notification TagIDLen: the ID length of the tag.
