Indy® RS2000, a surface mount module that comprises a
completely integrated reader solution for EPC Gen2 / ISO18000-63
(formerly 18000-6C) applications. The module was developed to
make embedding a high performance reader easy. The MTI M200-
RS module based on Impinj's Indy and R2000 builds on market-
leading Indy reader chip technology and integrates all of the
necessary components into a small package. Just provide power,
UART connection from a host, an antenna, and start reading tags.
It is fully tested and is certified for modular operation under FCC

    • ENABLE is used to enable or disable operation of the part. If this pin is driven low, the power supplies in the part will be disabled. M200-RS may be reset by toggling this pin. This pin must be driven high to enable the part.
  • Page 5 MTI M200-RS Hardware User’s Guide • STATUS toggles to provide an indication when the M200-RS is in active mode (for example, inventorying tags). Connection to an LED provides a visual indicator of the device’s activity. Optional connections: • GPIOs allow interaction with the M200-RS as both digital inputs and outputs. They may be used to trigger inventory, generate events based on inventory activity, or provide general-purpose user-controlled digital I/O.

  • Page 8: Power Supply

    UFL antenna port 2 Power Supply M200-RS is powered by a voltage applied to the VDC_IN pins (pins 1 and 11) relative to the GND pins. The supply voltage operating range is 3.2 V to 5.25 V. Average current consumption varies from about 1600 mA (8 W) to about 1 µA (5 µW) depending on the operating mode.

  • Page 9: Uart Communication

    Enable Pin The M200-RS has an ENABLE pin (pin 9) allows an external signal to put the module in Shutdown mode, which offers the lowest possible current consumption. The Enable pin can also be used to restart the module.

  • Page 10: Health And Status Pins

    1.2 �� Health and Status Pins The M200-RS has two pins that indicate the state of the device through their voltages: HEALTH (pin 23) and STATUS (pin 22). Both pins are outputs operating at a logical voltage level of 3.3 V, and can sink and source 2 mA each.

  • Page 11: Status Pin Behavior

    Blink alternate pattern with STATUS LED 2.6.2 Status Pin Behavior The STATUS pin indicates whether the M200-RS is operating in its active mode, or if some other condition exists. The pin is cycled high and low in specific patterns to indicate the state of the M200-RS.

  • Page 12: Wakeup Pin

    The WKUP pin operates at a 3.3 V logic level. It has a 10 kΩ typical pull-down resistor inside the M200-RS. Voltages outside of the maximum IO operating voltage range of -0.3 to 4.0 V should not be applied to the WKUP pin. This can cause permanent damage to the device.

  • Page 13: Pcb Transmission Line Types

    Z represents the characteristic impedance of M200-RS, 50 Ohms. For example, if a 40 Ohm transmission line is used, the reflection coefficient will be = 10 / 90 = 11.1%, thus 11.1% of it will be reflected back into the M200-RS, and only 88.9% of the power will be transmitted.

    λ divided by 10, or less. In 900 MHz UHF RFID applications, λ / 10 ~= 3.3 cm. Note The M200-RS development board PCB can be used as a reference for RF layout best practices.

  • Page 15: Using All 4 Antenna Ports With Uniform Connectors

    For this reason, in most 4 port readers based on the M200-RS, 2 of the 4 antenna ports of the M200-RS will need to be converted to match the other type.

  • Page 16: M200-Rs Reader Thermal Design

    M200-RS Reader Thermal Design As a high power RFID Reader module, M200-RS has the potential to produce significant heat during operation. In order to reduce the heat of the module, heat sinking can be implemented in a few different ways.

    Figure 11. At the interface between a module like the M200-RS and a PCB, reflowed solder can be used as a very effective heat conductor. To achieve the best heat conduction with reflowed solder, it is important that the solder form a contiguous bond between both objects.

  • Page 18: M200-Rs Operating Modes

    Indy RS2000 module mounted with Machined Chassis M200-RS Operating Modes M200-RS has five operating modes, a startup mode, and a shutdown mode. The modes and their capabilities are listed in Table 4-1, and the transitions between these modes are shown in Figure 12.

  • Page 20: Startup Behavior

    RS can only perform RFID reads while in Active mode. The IRI interface is only available in Active and Idle modes. While in Idle mode, the M200-RS is ready to quickly return to Active mode and start performing RFID reads. In Standby mode, a GPIO or WKUP pin event is required to return to active mode.

    U201 5.2.1 Key IC Descriptions U206 is the Indy M200-RS module. It is a completely integrated Gen2 UHF RFID reader, requiring only power, RF, and UART connections to read and write tags. U204 is an FTDI dual USB-UART transceiver that allows UART communication with a USB host.

  • Page 24: Connector Descriptions

    USB hosts cannot provide the current required for M200-RS operation, so care should be taken. JP200 and JP204 are 2x11 100 mil pitch headers that break out some of the M200-RS’s signals, and allow them to be connected to the rest of the circuitry on the development board.
