Data Sheet

1®DM2200-916VMThe DM2200-916VM is a 916.5 MHz transceiver module designed for wireless industrial sensor ap-plications. The transceiver module is equipped with two ADC inputs, three digital inputs, two digitaloutputs and a serial port. The communication range of the DM2200-916VM in an “open field” envi-ronment is typically 600 meters/hop. The DM2200-916VM combines RFM’s low-current ASH radiotechnology with low-power microprocessor technology to achieve very long battery life. TheDM2200-916VM employs RFM’s VersaMESHTM V2.0 mesh network protocol, which provides ro-bust wireless network routing, an integrated multitasking operating system, and an extensive appli-cation command set. The DM2200-916VM is certified under FCC 15.247 regulations.Rating Value UnitsAll I/O Pins Except VIN -0.3 to +4.0 VNon-Operating Ambient Temperature Range -50 to +100 oCAbsolute Maximum Ratings•RFM Multitasking VersaMESHTM V2.0 Network Protocol•Analog, Digital and Serial I/O Ports•3 V, Very Low Current Operation plus Sleep Mode•FCC 15.247 CertifiedElectrical CharacteristicsCharacteristic Sym Notes Minimum Typical Maximum UnitsOperating Frequency fO916.30 916.70 MHzModulation Type OOK on BPSK Spreading CodeRF Encoded Data Transmission Rate 9.6 kb/sReceive Mode:Average Input Current, 5 Vdc VIN Supply IR4.5 mAPulse Input Signal for 10-3 BER, 25 °C-102 dBmTransmit Mode:Peak Input Current, 5 Vdc VIN Supply ITP 32 mAPeak Transmitter Output Power PO10 dBmAverage Sleep Mode Input Current, 5 Vdc VIN Supply IS68 µAAnalog Input Measurement Range (12-bit ADC) 0 VDD VExternal Source Impedance to Analog Input 10 KDigital Output Source Current, 1K Load 1 mADigital Output Sink Current, 1K Load 1.2 mASerial Port Data Rate 19.2 kb/sInternal Power Supply Input Voltage Range 3.1 14.0 VdcExternal Power Supply Voltage Range VDD 2.9 3.7 VdcExternal Power Supply Voltage Ripple 10 mVP-POperating Ambient Temperature Range TA-40 +85 oC916.50 MHzTransceiverModuleIn Development
DM2200-916VM Theory of OperationThe major components of the DM2200-916VM includethe TR8100 ASH transceiver and the TI MSP430F148microcontroller. The TR8100 operates on 916.5 MHz,with a nominal output power of 10 mW. The MSP-430F148 can operate referenced to either a 32.768 kHzor 6 MHz crystal.The MSP430F148 UART is used to provide a CMOSserial interface on connector J2. The microcontroller’sI/O pins are also available on connector J2 for externalmonitoring or control. Note that GP0 is dedicated tomeasuring the value of the received signal strengthindicator (RSSI) circuit and should always be set as ananalog input. The three LEDs on the transceiver moduledisplay RF communication activity.DM2200-916VM operation is based on RFM’s multi-tasking VersaMESHTM network protocol, which supportsdata and command transfers through both the serial in-terface and the RF channel. See the VersaMESHTM Pro-tocol User’s Guide for further details.256789104321GND VIN11 12 13 14VREN VDD TD0 TD1 TW S TCK RST CFG0CFG1CFG2CFG3 GNDJ11234567891011121314J23 VD CGRNYELREDTR 8100ASHTransceiverRSSILowVoltageResetTXM O DRXDATACFGDATCFGCLK3 VD C VoltageRegulatorD M 2 2 0 0 B lo c k D ia g ra mGNDGP7GP6GP5GP4GP3GP2GP1GP0/RSSIRTSCTSTXDRXDGNDM SP430F148M icrocontrollerCFGFigure 1
DM2200-916VM FCC CertificationThe DM2200-916VM is certified for operation underFCC Part 15 Rules, Section 15.247. When theDM2200-916VM is run from an off-board power supply(applied to J1-4), the supply voltage must be limited toa maximum of 3.7 Vdc, and the power supply voltageripple must not exceed 10 mVP-P.FCC Labels and NoticesA clearly visible label is required on the outside of theuser’s (OEM) enclosure stating that this product con-tains a DM2200-916VM radio module, FCC ID:TE6-DM2200A.This device complies with Part 15 of the FCC rules.Operation is subject to the following two conditions: (1)this device may not cause harmful interference, and (2)this device must accept any interference received, in-cluding interference that may cause undesired opera-tion.WARNING: This device operates under Part 15 of theFCC rules. Any modification to this device, not ex-pressly authorized by RF Monolithics, Inc., may voidthe user’s authority to operate this device.DM2200-916VM ApplicationsThere are two ways to use the DM2200-916VM in anapplication. The transceiver module can be used with acompanion application interface board, the IM2200. TheIM2200 has provisions for powering the transceivermodule from a USB cable, an external unregulated DCsupply such as a 5 Vdc “wall” transformer, an externalregulated 3 Vdc power supply, or an external battery.The IM2200 also provides the choice of UART, RS232,RS485 (single drop) or USB for a host computer serialinterface. In addition, the IM2200 includes captured-screw terminal strips for connecting analog inputs, digi-tal logic inputs, digital logic outputs and form C relayoutputs. Refer to the IM2200 data sheet for additionaldetails.The DM2200-916VM can also be integrated into theuser’s own application board. The DM2200-916VM pindescriptions are given in the Table on pages 4 and 5.The transceiver module pin-out locations are show inFigure 2, and the PCB layout for the mating connectorsis shown in Figure 3.The operating range of the DM2200-916VM criticallydepends on the antenna being located properly. Whenusing the standard DM2200-916VM antenna (RFM partnumber 400-1687-001), care should be taken to keepthe antenna at least 0.5 inch away from the sides of itsenclosure. The enclosure must be made from a plasticwith low RF attenuation, such as fiberglass, PVC orABS. Note: other antenna configurations are possible,but each new antenna configuration must be added tothe DM2200-916VM FCC module certification beforedeployment. Contact RFM for details.The DM2200-916VM enclosure should be mounted sothe antenna is at least 4 feet off the ground, and ideally6 or more feet off the ground.The DM2200-916VM has an on-board regulator inputon Pin J1-2. To use the on-board regulator, connectJ1-3 to J1-2 and apply a voltage to this connection of atleast 3.1 Vdc, but not greater than 14 Vdc, including rip-ple variations. When running from the on-board regula-tor, up to 5 mA is available on J1-4 to operate externalcircuitry. Any external circuitry connected to J1-4 mustnot induce more that 10 mVP-P ripple on the regulated3 Vdc at this pin.The DM2200-916VM can also be run from an off-boardregulated supply or a battery. In this case, connect J1-3to ground, leave J1-2 unconnected, and apply the regu-lated supply or battery input to J1-4. Note the input volt-age range for J1-4 must be in the range of 2.9 to 3.7Vdc, with no more than 10 mVP-P ripple.Only pins J1-2 and J1-3 are rated to operate from asupply voltage higher than 3.7 Vdc. Further, care mustbe taken so that analog or logic inputs applied to thetransceiver module stay within the voltage range of 0 toVDD (voltage at J1-4). Applying a voltage outside of the0 to VDD voltage range to an analog or logic input candamage the module.The DM2200-916VM has current limiting protection re-sistors on most of the I/O pins. These limit the currentthat a logic output can source or sink. Any DM2200-915.50SN pin defined as an output should be used onlyto drive a high impedance load such as a CMOS logicinput or a MOSFET transistor.3
