MPR-1712 - 5 - 6/19/2008 1 INTRODUCTION AWID's Sentinel-Sense MPR-1712 is a Radio Frequency IDentification (RFID) reader module with RS-232 and USB I/O interface that works with most leading passive UHF and HF tags. The reader module comes with a unique combination of long read range, small size (credit card), dual frequency and low power consumption. Its primary applications are access control, asset management and tracking, and fleet management applications. The MPR-1712 reader modules are delivered with firmware version US0-211h1-xx.yy.00. In order to operate an MPR-1712 you will need the following:  PC running Windows1 2000 or higher, CD-ROM drive, USB and/or RS-232 serial port.  Host software (AWID’s demo software or your own custom software) 1.1 SPECIAL FEATURES • UHF Multi-Protocol: ISO-18000-6 Type B/C, EPC Class 1 Gen 2 • HF Multi-Protocol: ISO-14443 A/B, ISO-15693, Milfare Standard 1K and 4K and Mifare Ultralight • Thin passive tags with long-range performance • RS-232 and USB outputs • 1 Though MPR-1710 can also be controlled from a non-Windows programming platform, AWID demo and FW upgrade programs are applications to run in Windows.

MPR-1712 - 7 - 6/19/2008 Pin Function Pin Function 1 USB 6 GND 2 USB D- 7 +3V Aux Data 3 USB D+ 8 +3V TTL Rx 4 +5.5 V 9 +3V TTL Tx 5 +5.5 V 10 GND 2.3 MEASURING READ DISTANCE Make sure you know the tag types. For certain readers and tags, user must also be mindful of the tag’s orientation and the reader’s antenna orientation, what mounting surface the tags are designed for and how the tags are supposed to be mounted. Any departure from its intended purpose will drastically affect the reader’s ability to energize the tag and its read range. When measuring the reader’s read range, make sure that the tag is properly oriented to the reader antenna, and for optimum performance, be sure the operator’s finger is not within three (3) inches of the tag’s antenna surface.
MPR-1712 - 8 - 6/19/2008 3 INSTALLATION & OPERATION GUIDELINES For ease of explanation, MPR reader in this section refers to an RFID device that consists of MPR-1712 and a high performance circular polarized antenna inside a splash proof, UV stabilized housing case. The module should be installed on a heat sink. Example of a heat sink could be an aluminum plate of size 8”x8”x0.1” exposed to convection air flow. The screws at the bottom of module shall be used for mounting the module on the heat sink. 3.1 GENERAL WIRING REQUIREMENTS All the MPR reader wiring should be continuously shielded. AWID recommends using #24 AWG up to #22 AWG, longer distances and higher current consumption on the power supply line will require larger gauge wires. TABLE 3.4-1: Data Line’s Wiring Requirement WIRE SIZE #22 AWG (0.6 mm Dia.) #24 AWG (0.5 mm Dia.) RS-232 50 ft (15 meters) 50 ft (15 meters) 3.2 WIRING DIAGRAMS See section 2.2 for pin assignment for the RS-232 connector of MPR-1712. The MPR RS-232 interface is a short distance serial interface, a full command set for the standard serial interface is not necessary, therefore only transmit, receive and ground wires are used. Sense input is an enable input, which is traditionally used to activate the RF energy of the reader and to start the read functions.

Follow with some commands.
MPR-1712 - 10 - 6/19/2008 5 SOFTWARE PROGRAMMING AND SYSTEM OPERATION NOTES 5.1 SYSTEM OPERATION 5.1.1 Running a Custom Software Application or the AWID Demo Program If AWID Demo Program is not used, it is expected user will launch a Custom Software Application developed using the MPR-1712 Protocol to issue commands to the MPR reader/module as specified. 5.1.2 Operating Modes Typical operating modes for MPR readers can be grouped into the following modes: Search Mode This mode is used when operator or user is not certain what family of tags is placed on the items to be tracked. Since most tags are deterministic in nature, MPR reader must cycle through each and every protocol, issue a protocol specific inquiry, to hail and to wait for a response from tags of that specific protocol. Therefore, if there are many different protocols, for an untrained observer, the reader response will appear sluggish. Mixed Mode This mode assumes the user is aware of the types of protocol in use, and furthermore, the user made a determined effort to operate the reader in a mixed protocol mode. In this mode, the user can decide how many and which specific protocols to be selected. Once Mix Protocol Mode is selected, the reader will routinely cycle through each protocol, dwell long enough for the reader to wait for a response and then move on to the next protocol. It should be noted that in a mixed protocol mode, the tag must have sufficient time to respond to the reader, and therefore, it can only be used on a conveyor belt arrangement, with specific speed restrictions. Single Protocol Mode Single protocol is the normal mode of operation, where the protocol type is known and many tags are expected to pass through the readers. 5.2 USERS NOTE For System Integrators and/or Software Developers System Integrators and/or software developers should get familiar with the MPR-1710 1712 Protocol specifications for developing applications that control an MPR-1710. For Custom System Users For custom system user, please refer to your host software user guide for information regarding system and software operations For Demo Software Users
