Introduction
The 3M Compact RFID Reader 1000 is a member of the 3M family of Radio
Frequency Identification (RFID) products. RFID is a wireless data acquisition
method used to remotely retrieve product data such as part number, date of
manufacture, quantity, version, and other information. All RFID systems are
comprised of the following components:
Transponders (or tags) attached to a product
Reader (or Interrogator) to read and write tag data
Reader (or Interrogator) Antenna

1000 Overview
The 1000 operates in the 902 MHz to 907,5 MHz and 915 MHz to 928 MHz
Brazil Anatel band. The 1000 supports ISO18000-6B (ISOB), ISO18000-6C
(ISOC), Electronic Article Surveillance (EAS) Alarm protocols, or any
combination of the protocols. The reader supports dense reader mode for ISOC,
and may be deployed into various Automatic Vehicle Identification (AVI)
installations. The 1000 provides cabled external interface options including RS-
232 serial at 115200 Baud, Ethernet at10/100 Mbps, USB 1.1, and general
purpose digital I/O.
The 1000 is equipped with four (4) RFID antenna ports using reverse-polarized
TNC connectors. The antenna ports are multiplexed, and only one port is
transmitting at any given time. Through on-board electronic switching the 4-
and configuration can be operated in bi-static or mono-static transmit (TX) and
receive (RX) configurations. In mono-static mode the selected antenna port
provides both the TX and RX function. In bi-static mode one antenna port
provides the TX function, another antenna port the RX function.
Conducted RF output power is limited to 1 Watt at the input of the RFID
antenna selected for product installation. The antenna gain and RF cable loss
parameters are factory set.
In addition to flexibility in RF power level, the transmitter has been optimized to
handle the demanding requirements of dense reader modes. These optimizations
include the use of phase reversal keying and substantial filtering to reduce out-
of-band emissions to well below industry standards.
