i-PORT MB – Manual 1 INTRODUCTION 1.1 Fundamentals IDENTEC SOLUTIONS’ ILR® (Intelligent Long Range®) technology is the next generation of long range RFID (Radio Frequency IDentification). The objective is wireless and automated data collection over large distances. HOW RFID WORKS Data is transmitted via high frequency radio waves between a tag and an interrogator. Information stored on the tag can be read and processed.
i-PORT MB – Manual Figure 1: ILR System Components ILR System Components: • Tags from the i-B series transmit stored data over large distances. The high data transmission rate ensures optimal communication. • The fixed reader (i-PORT MB) receives the data transmitted by the tags in regular intervals and buffers the received data for later transmission via a RS422 network connected to a master PC.
i-PORT MB – Manual 2.0 COMPONENTS 2.1 i-PORT MB The i-PORT MB is a reader for the i-B series of ILR® Broadcast Tags. Built into a compact plastic housing, the i-PORT MB receives transmissions from the i-B tags at distances of up to 100 meters (300 feet). Connection to the host system is established via a RS422 interface, resulting in the capability to connect up to 8 readers in a Daisy Chain using commercially available CAT 5 cables and connectors. A simple master/slave protocol enables data exchange.
i-PORT MB – Manual Orientation Diagrams: Elliptical polarized antenna Elevation Azimuth Linear Polarized Antennas Because of the smaller apex angle (60º), this antenna is more suited to selective data collection and restriction of read zones. Depending on the direction of mounting, the antenna’s field is either vertically or horizontally polarized, requiring the tag to have the same orientation.
i-PORT MB – Manual Orientation Diagrams: Linear polarized antenna Elevation Vertical Polarization Azimuth Horizontal Polarization Antenna Orientation 2.3. i-B Tag This active tag is particularly suited for: - Identification - Tracking and Tracing Using ILR technology, distances of up to 100 meters (300 feet) can be achieved with this tag. An operation lifetime of up to 6 years (depending on ping rate) can be expected due to the tag’s minimal energy requirement.
i-PORT MB – Manual Vertically Polarized Horizontally Polarized Polarization is dependent on orientation and is rotation symmetrical. 3.
i-PORT MB – Manual Cable losses as a function of cable length are displayed in the above diagram. The values are based on an RG58 coaxial cable at a frequency of 900 MHz. In the diagram above, the relative range is displayed as a function of the cable length. Relative because the range is dependent on the environment of the system. Under ideal conditions (free field, i-PORT R2), ranges of up to 100 meters (300 feet) can be achieved.
i-PORT MB – Manual Alignment of Antennas: Align the antennas with the tags or the objects to be monitored. Linearly polarized antennas must have the same polarization as the tags, either horizontal or vertical. Circular polarized antennas are not dependent on the polarization of the tags. 3.1 Mounting the i-PORT MB Dimensions without mounting kit and with end cap Version 1.1 02.02.
i-PORT MB – Manual Dimensions without mounting kit and without end cap Mounting kit Version 1.1 02.02.
i-PORT MB – Manual The mounting kit is to be clipped on the back of the i-PORT MB, there is 5 mm space left for the screws between the mounting kit and the reader. Use the two mounting holes (diameter 4,5 mm) to attach the i-PORT MB mounting kit to a suitable mounting surface. Once the mounting kit is fixed, clipped in the i-PORT MB reader. Please add to the i-PORT MB dimensions approximately 70 mm on the antenna side and 40 mm on the cable side to calculate the required mounting space.

i-PORT MB – Manual 4.0 COMMUNICATION PROTOCOL 4.1 Telegram Structure, Escaping and CRC Operation of the i-PORT MB follows strictly the Master/Slave principle. Readers are slaves and there is no information sent by the readers unless requested by the master computer. The data is divided into separate messages with the following structure: SOH Addr Cmnd data ... Crc16 EOT SOH and EOT are the ASCII characters 0x01 and 0x04, respectively. Addr is the bus address of the telegram recipient.
i-PORT MB – Manual Using this procedure it is ensured, that neither the EOT nor the SOH character will appear in a message sent by the reader and the host software gets a clear indication when a telegram starts and ends. Please note, that due to these inserted characters the maximum telegram length can be nearly doubled so the host program has to provide a sufficiently large reception buffer. If an addressed device detects an error when receiving a command (f.e.
i-PORT MB – Manual 4.2 Get version command Get Version Command telegram This command is used to get both a binary version number plus a version identification string from the reader. Parameter Range Length/byte Start Address Command Crc16 End SOH 1 1 1 2 1 0x33 EOT Get Version Response telegram The reader responds with a message as follows: Version 1.
i-PORT MB – Manual 4.3 Get Tags command Command telegram After power-up the reader automatically starts reading and stores detected tags in an internal list. With this command the tags can be retrieved from the reader: Parameter Range Length/byte Start Address Command SubCmd CRC16 End SOH 1 1 1 1 2 1 0x41 0x00 EOT Remark Response telegram The Reader can be configured to send more than one Response telegrams to one Get Tags Command.
i-PORT MB – Manual process_response_telegram(); } 2 The transmitted AgeCount contains the lower 8 bits b0..b7 and the highest 8 bits b20..b27 of the tag age counter c0..c15 (this is the result of a “mapping” of the 32 bit age counter on the tag to 2 byte transmitted by RF). The lowest bits are used to change telegram contents and encryption between transmissions while the upper bits are used to estimate tag life (and remaining lifetime).
i-PORT MB – Manual 4.4 Get Tag extended command Command telegram This command corresponds to the “Get Tags” Command but requests additional information.
i-PORT MB – Manual TelegramCount crc16 End Delimiter 0/1 EOT This byte is only transmitted if the SubCmd is 0x01. It is incremented each time it is transmitted. If the value on host and reader are inconsistent the complete list of tags can be scheduled for retransmission with parameter 0x15.
i-PORT MB – Manual 4.5 Get Tag Full command This command corresponds to the “Get Tags extended” Command but requests additional information regarding all antennas.
i-PORT MB – Manual TelegramCount crc16 End Delimiter 0/1 EOT This byte is only transmitted if the SubCmd is 0x01. It is incremented each time it is transmitted. If the value on host and reader are inconsistent the complete list of tags can be scheduled for retransmission with parameter 0x15.

i-PORT MB – Manual Inhibit Time: This parameter defines the maximum time the tag must not be detected by the reader before to be removed from the internal list. A tag is removed only if it is marked as reported. If the tag was not marked as reported, it will stay in the list as long as it is not reported or removed from the list. If List behavior is equal to 4 then the tag is removed from the list as soon as it is reported so this parameter has no effect.
i-PORT MB – Manual 4.9 Reader status information The GetParameter Command (with parameter ID = 4) is identified as the GetStatus command. The get status command returns 32 bits, this table details the type of error each single bit indicates. If a bit is set, it indicates the defined error occurred at least once since the last Getstatus command was sent. All status bits are cleared after reception of the Getstatus command. More than 1 bit can be set at the same time.
i-PORT MB – Manual 5.0 INSTALLATION- CONFIGURATION This chapter provides some useful hints and procedures how the reader should be used under different operating modes 5.0 Device enumeration On power-up the “To Slave” RJ45 port of the reader transparently transmits and receives data from and to the “To Master” RJ45 port. The device responds to either the broadcast address or the last static address assigned to the device.
i-PORT MB – Manual 5.2 Normal initialization (“application on host starting up”) − − − − Enumerate readers check that voltages are OK For each reader get serial number and compare to values stored on host. Report mismatch as error, if desired automatically redo first time initialization. 5.3 Normal operation (“host application loop after startup”) − − The host application typically polls the readers for data (with the commands “Get Tags” or “Get Tags Extended”).
