Chapter 1 Introduction Chapter 1 Chapter 1 MR400 Integration GuideIntroduction Overview The MR400 is a RFID Reader that supports the GEN 2 EPC (Electronic Product Code). protocol, in the UHF frequency band. The reader architecture is intended to address the requirements of operation in different world regions with different frequencies, data rates and compliance specifications.
1-2 MR400 RFID Reader Module, Integration Guide Theory of Operation The MR400 is a UHF (860MHz - 928MHz) RFID reader module. The MR400 RFID Reader Module is used to read and write UHF passive RFID tags complying to EPCglobal Gen2 standard. Communication between a reader and a tag occurs in a half-duplex reader-talks-first manner. Commands from the reader is sent to the tags on the forward link modulated on the transmit carrier followed by a CW transmission.
Introduction 1-3 Baseband Processor The Baseband Processor responsible for sending out appropriate commands in accordance to a selected tag protocol to interrogating or accessing tags. Upon receiving the base band data from the Transceiver, the Baseband Processor applies the appropriate algorithm to detect and extract the tag responses from the incoming data stream. The data then will be buffered and sent to Controller for uploading to the Host.
1-4 MR400 RFID Reader Module, Integration Guide Host Interface The host interface connector consists of a PCB connector p/n Molex 54548-1470, 0.50mm (.020") pitch FFC/FPC connector, 1.20mm (.047") height, right angle, SMT, ZIF, bottom contact style, with 14 circuits. Table 1-1 Host Interface Connector J1 Pin # Signal Names Dir Description 1 +5Vdc I Regulated +5Vdc (4V - 5.5V), 2A max, 2 +5Vdc I Regulated +5Vdc (4V - 5.5V), 2A max, 3 +5Vdc I Regulated +5Vdc (4V - 5.
Introduction 1-5 Mechanical Characteristics The MR400 mechanical characteristics include the physical dimensions, the weight and the enclosure and EMI shielding. Dimensions Dimensions: 85.6mm long, by 54mm wide, by 5 mm thick Weight Weight TBD Enclosure and EMI Shielding The MR400 is enclosed in a standard frame similar to PCMCIA type II card. The housing frame has two MMCX board edge antenna connectors at one end, and a 14pin FFC/FPC connector at the other end for host interface.
1-6 MR400 RFID Reader Module, Integration Guide Environmental Characteristics Thermal Management A heat sink is required on the MR400 to transfer the heat to the outer case. Temperature and Humidity Operating: -20oC to 65oC (RH 5% to 85%, non-condensing) Storage: -40oC to 70oC (RH 5% to 85%, non-condensing), non-operational. Thermal Shock: -20oC to +65oC, 30 min dwell, 100 cycles. ESD Pin Discharge: +/- 2 kVdc Indirect Discharge: +/- 8kVdc Contact Case: +/- 1.
Chapter 2 Installation Chapter 2 Chapter 2 InstallationMR400 RFID Reader Module, Integration GuideInstallation Overview This chapter provides information for mounting and installing the MR400. Physical and electrical considerations are presented, together with recommended window properties and housing designs. Unpacking Remove the MR400 from its packing and inspect the reader for evidence of physical damage.
2-2 MR400 RFID Reader Module, Integration Guide MR400 Installation Before installing the MR400 RFID reader module into the host equipment, consider the following: • TBD • TBD • TBD Housing Design The RFID reader module housing design must protect the module from impact and adverse environments. Environment The RFID reader module must be sufficiently enclosed to prevent moisture and/or dust from interfering with the MR400 operation.
Installation 2-3 Using the MR400 Some applications require the MR400 be mounted to read tags that are automatically presented, or that are presented in a pre-determined location. In these applications MR400 positioning (with respect to the symbol) is critical. Failure to properly position the MR400 with respect to the tag may lead to degraded or unsatisfactory reading performance. Locating Parameters: • TBD • TBD • TBD Accessories The available accessories for the RFID reader module.

Byte Stream Protocol Chapter 3 Chapter 3 Chapter 3 MR400 RFID Reader Module, Integration Guide Byte Stream Protocol With the MR 400 The Byte Stream Protocol can be used to communicate with the MR 400 reader, using a two wire serial link TTL at 115200 baud rate. Request and Response Packets The byte stream packet follows generalized packet format for request and response packet. This section describes the packet format which most request and response examples in this document will use.
3-2 MR400 RFID Reader Module, Integration Guide For every request sent to the reader there may be one / more response packets that the reader sends back to the host. A Typical Response Packet has been described in the following table: Table 3-2 Field Number of Bytes (Size) Value Description SOF 1 0x01 Described in Request Packet description. Node Address 1 0~0x1F Described in Request Packet description. Packet Length 1 See Description Described in Request Packet description.
Byte Stream Protocol 3-3 Byte Stream Command List The following commands are supported by the MR400 reader. • Read Full Field Command (22hex) • Set Parameter Block Command (23hex) • Get Parameter Block Command (24hex) • Get Reader Status Command (14hex) • Set Frequency Channel Command (1Chex) • Read With Payload Command (31hex) • Kill Specific (32 hex) • Write Tag (33hex) Read Full Field Command (22hex) Read all RFID tags using one antenna port of the addressed reader.
3-4 MR400 RFID Reader Module, Integration Guide Read With Payload Command (31hex) Only the first antenna port must be passed in the request packet while using this command with the MR400 reader. No Antenna combination options should be used with this command when using it with the MR400 since the MR400 does not support combination of antennas. For more information on this command refer to the Matrics API Programmers Manual.
