MPR-2010AR 1 Page 5 Doc# 041308 INTRODUCTION AWID's Sentinel-Sense MPR-2010AR is a long-range (12 to 15 feet) Radio Frequency IDentification (RFID) reader with RS-232 I/O interface that works with most leading UHF passive tags. This reader comes with a unique combination of long read range, small size, and low power consumption. It has an internal power converter, allowing it to work with a wide range of supply inputs without affecting its performance.
MPR-2010AR Page 6 Doc# 041308 is how the tags’ internal data are “conveyed” to the reader. The reader in turn monitors the perturbation of the RF energy field, and thereby receives the varying degree of signal reflected from the tags. One of the unique design features for a (single-antenna) RFID reader is that it must simultaneously transmit a strong CW signal and at the same time, receive a weak reflected signal with little frequency separation.
MPR-2010AR Page 7 Doc# 041308 well-designed dual-antenna reader can usually provide 25 to 30 dB of isolation between the two signal paths, reducing the unwanted signal in the receive chain to –20 dBm. However, when the RFID reader antenna is facing a tag placed on a large metallic object at a distance of 12 inches, the reflected transmitter signal at the receiver input can be as high as 13dBm, thereby eliminating any advantage of the dual-antenna design.

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.
MPR-2010AR 3 3.1 Page 10 Doc# 041308 INSTALLATION & OPERATION GUIDELINES SITE SURVEY Always conduct a site survey before starting installation. Avoid any possible sources of interference. For best result, use a spectrum analyzer with a wideband antenna and set the spectrum analyzer in Max Hold mode to gain measurement of the maximum signal strength on the airwave. If the MPR-2010AR reader is not installed properly, the performance will be degraded.

MPR-2010AR’s 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.

Please note that the threaded inserts are closedended, the user must select screws with the exact length to ensure proper tightening of the mounting screws. In cases where the reader aiming is critical, please order antenna-mounting bracket (P/N LRMB) from AWID. This mounting bracket provides pan/tilt adjustment for the reader.
MPR-2010AR 5.2 Page 15 Doc# 041308 USERS NOTE For System Integrators and/or Software Developers System Integrators and/or Software developers should get familiar with the MPR Serial Communication Protocol specifications for developing applications that control MPR2010AR readers.
