| www..com WJM1000G Next Generation RFID Reader Module Based on WJC200 Gen2 RFID reader chipset Key Features x Multi-protocol support: ISO 18000-6C (Gen2) & ISO 18000-6B Dynamic RF output power: 10 dBm to 24 dBm range Two antenna port for added flexibility Power saving modes to extend battery life Special printer commands to enable high throughput tag/label fulfillment WJC200 Gen2 reader chipset based design Applications: x x x x x x x x Printers Item-level RFID Mobile & handheld devices WJ Communications' WJM1000 UHF RFID module is designed to enable OEMs, VARs and System Integrators to integrate RFID UHF Gen2 capability into new and existing short range applications such as printers and Mobile /handheld devices. By leveraging WJ's WJC200 Gen2 chipset, the WJM1000 enables cost effective, compact RFID-enabled devices. The WJM1000 extends industry leading features including Gen2 dense reader environment (DRE) . The WJM1000 reader module's simple but powerful command set allows for fast creation of custom applications via an open-source DLL and API. The WJM1000 printer-commands, includes Single API command for optimized, high throughput fulfillment of Gen2 labels/tags, increases printer throughput while minimizing overheard. The WJM1000 can be set to transmit a range of output powers, providing increased flexibility to enable optimal settings for fulfillment of labels/tags inside a printer. The module operates over the North American UHF frequency band (902-928 MHz) and includes the RF, digital circuitry and embedded firmware required for ISO18000- 6C (UHF Gen2) and ISO 18000-6B international standards. 3.3V CMOS level serial communications and 4 GPIO lines are available on a 15-pin connector. Mounting holes provide fast and easy mechanical integration. WJ's free demo software offers quick evaluation of the module without software development.

Grounding this pin shuts off entire module. Minimum logic high voltage is +2.5V. 5V tolerant. Low impedance driver or a pull up resistor less than 2K required. 3.3V CMOS logic-level UART transmit pin 5V tolerant CMOS logic-level UART receive pin 5V tolerant Active Low Reset Pin. When held low, WJM draws current but will not respond to commands. If nBL/nPD is held low as nRESET is brought high, the WJM enters Bootloader mode. If nBL/nPD is held high as nRESET is brought high, the WJM application starts. 5V tolerant Active Low Bootloader/PowerDown pin. This pin serves two functions. 1) If this pin is low at the rising edge of nRESET (including power-on), the Bootloader is activated for writing a new Firmware application (FW). If it is high, FW starts. 2) Once FW starts, bringing this pin low enables sleep mode. The module will not respond to API commands in sleep mode. Keep it high for normal operation. 3.3V logic-level 3-state output: Logic high: OK Tri-State: Sleep Mode Logic low: Error This has not been implemented in FW. Currently FW configures these pins as outputs, they display various debug and status signals to LEDs. If unused they can be left un-connected. Specific uses for these pins have not been finalized. 10 nBL/nPD 11 STATUS_LED 12 13 14 15 GPIO1 GPIO2 GPIO3 GPIO4 Copyright WJ Communications 2007. Subject to change without notice.
