DOTR221 READER MODULE USER GUIDE D.O.Tel Co., Ltd. #412, Kolon Science Valley 2 nd 811 Gurodong, SEOUL, KOREA 152878 Copyright 2008 Note: FCC Section 15.21 "Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment." Chapter 1 INTRODUCTION The DOTR221 module is a compact UHF RFID reader module which is compliant with the ISO18006C (EPC class1 Gen2) protocol. It is intended to be used in conjunction with the accompanying antenna and a host computer (not supplied). The small physical size allows the module to be easily integrated with a mobile host computer, such as a Personal Digital Assistant. The module is designed to be operated off a single cell lithium ion battery, and has two host interface options: USB and UART. WARNING 1. ESD precautions: This module contains electrostatic sensitive components. Handle the product at a staticfree workstation, and wear a static grounding strap always. Observe standard ESD precautions. 2. This module does not contain fuses or other protective devices. Be extra careful when applying power to make sure voltage and polarity are correct. 3. Do not attempt to open the cover. There are no serviceable parts inside. 4. Provide good thermal conduction of the module or good ventilation around the module. As the module consumes around 4 watts of power, it can be hot when operated continuously. Adequate cooling should be provided to ensure reliability. 5. Do not operate the product in an explosive atmosphere or in the presence of flammable gases or fumes.

DO NOT CONNECT TO ANYTHING. 12 USB 5V In USB Vbus Voltage (+5V). This pin is for sensing the USB Host only. The module is not powered from this voltage. Notes: 1. All of the supply pins (Pins 1,2, 5, 6, and 7) must be used in order to minimize voltage drop at the connector junctions. 2. TX / RX and I/O classification is from the module’s point of view. 3. Leave pin 11 open. Do not apply any voltage, or the module will become nonfunctional. 3.2 TTL INTERAFACE UART communication is provided on the TXD and RXD lines. Baud rate is fixed at 115.2kbps and no handshaking (8 data bits, no parity, 1 stop bit). Details for communication protocols are described in the software chapter. 3.3 USB Interface The module provides full speed compliant USB interface (12Mbps). Note: The module is set to communicate via UART port at the factory. CHAPTER 4 Operation 4.1 Antenna Connection A good antenna must be connected before applying power. The antenna must have a low VSWR value (less than 1.25) in the entire frequency range of 902 through 928MHz to ensure maximum read range performance. Care should be taken when connecting the antenna cable to the antenna connector, as the antenna connector is very small and fragile. 4.2 Power Supply The reader module is designed to operate off 3.7V nominal supply voltage which is typically available from a single cell lithium ion battery. Other power sources can be used as long as it is within the specified voltage range of 3.4V to 4.2V. Care must be excersized for correct polarity. Pins 5, 6, 7 and the housing are ground while Pins 1 and 2 should be connected to +3.7V. 4.3 GP0 and GP1 ports. GP0 (Pin 10) port is an active high enable control to power up the reader module. A logic voltage above 2.5V (?) will turn on the reader while level below 0.5V (?) will turn off the reader. GP1 (Pin 11) should be left open for internal pulldown to work. Pulling the GP0 and GP1 ports to a high level will erase entire contents of internal flash memory. This mode is used at the factory. Consult with the manufacturer to use this function. 4.4 TXD and RXD ports TXD (Pin 8) and RXD (pin 9) are UART communication ports and TX/RX notation is from the reader module’s point of view. These ports provide a single speed (115.2kbps) serial communication without flow con…
