In Development DM2200916VM ® • 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 Certified The DM2200-916VM is a 916.5 MHz transceiver module designed for wireless industrial sensor applications. The transceiver module is equipped with two ADC inputs, three digital inputs, two digital outputs and a serial port. The communication range of the DM2200-916VM in an “open field” environment is typically 600 meters/hop. The DM2200-916VM combines RFM’s low-current ASH radio technology with low-power microprocessor technology to achieve very long battery life. The DM2200-916VM employs RFM’s VersaMESHTM V2.0 mesh network protocol, which provides robust wireless network routing, an integrated multitasking operating system, and an extensive application command set. The DM2200-916VM is certified under FCC 15.247 regulations. 916.50 MHz Transceiver Module Absolute Maximum Ratings Rating Value All I/O Pins Except VIN -0.3 to +4.0 Non-Operating Ambient Temperature Range -50 to +100 Units Electrical Characteristics Characteristic Sym Operating Frequency fO Modulation Type Notes Minimum Typical 916.30 Maximum Units 916.70 MHz OOK on BPSK Spreading Code RF Encoded Data Transmission Rate 9.6 kb/s 4.5 mA -102 dBm Receive Mode: Average Input Current, 5 Vdc VIN Supply IR -3 Pulse Input Signal for 10 BER, 25 °C Transmit Mode: Peak Input Current, 5 Vdc VIN Supply ITP Peak Transmitter Output Power PO 10 dBm IS 68 µA Average Sleep Mode Input Current, 5 Vdc VIN Supply Analog Input Measurement Range (12-bit ADC) 32 External Source Impedance to Analog Input Digital Output Source Current, 1K Load mA VDD 10 mA Digital Output Sink Current, 1K Load 1.2 mA Serial Port Data Rate 19.2 kb/s Internal Power Supply Input Voltage Range External Power Supply Voltage Range VDD 3.1 14.0 Vdc 2.9 3.7 Vdc 10 mVP-P External Power Supply Voltage Ripple Operating Ambient Temperature Range TA -40 +85 D M 2 2 0 0 B lo c k D ia g r a m 3 V D C G R N Y E L R E D C F G 1 4 G N D 1 3 G P 7 1 2 G P 6 1 1 G P 5 1 0 G P 4 G P 3 G P 2 G P 1 G P 0 /R S S I R T S C T S T X D R X D G N D C F G C L K C F G D A T T R 8 1 0 0 A S H T r a n s c e iv e r M S P 4 3 0 F 1 4 8 M ic r o c o n tr o lle r R X D A T A T X M O D R S S I L o w V o lta g e R e s e t 3 V D C J 2 V o lta g e R e g u la to r J 1 G N D V IN V R E N V D D T D 0 T D 1 T W S T C K R S T 1 0 1 1 1 2 1 3 C F G 0 C F G 1 C F G 2 C F G 3 1 4 G N D Figure 1 DM2200-916VM Theory of Operation monitoring or control. Note that GP0 is dedicated to measuring the value of the received signal strength indicator (RSSI) circuit and should always be set as an analog input. The three LEDs on the transceiver module display RF communication activity. The major components of the DM2200-916VM include the TR8100 ASH transceiver and the TI MSP430F148 microcontroller. The TR8100 operates on 916.5 MHz, with a nominal output power of 10 mW. The MSP430F148 can operate referenced to either a 32.768 kHz DM2200-916VM operation is based on RFM’s multior 6 MHz crystal. tasking VersaMESHTM network protocol, which supports data and command transfers through both the serial inThe MSP430F148 UART is used to provide a CMOS terface and the RF channel. See the VersaMESHTM Proserial interface on connector J2. The microcontroller’s tocol User’s Guide for further details. I/O pins are also available on connector J2 for external DM2200-916VM FCC Certification The operating range of the DM2200-916VM critically depends on the antenna being located properly. When using the standard DM2200-916VM antenna (RFM part number 400-1687-001), care should be taken to keep the antenna at least 0.5 inch away from the sides of its enclosure. The enclosure must be made from a plastic with low RF attenuation, such as fiberglass, PVC or ABS. Note: other antenna configurations are possible, but each new antenna configuration must be added to the DM2200-916VM FCC module certification before deployment. Contact RFM for details. The DM2200-916VM is certified for operation under FCC Part 15 Rules, Section 15.247. When the DM2200-916VM is run from an off-board power supply (applied to J1-4), the supply voltage must be limited to a maximum of 3.7 Vdc, and the power supply voltage ripple must not exceed 10 mVP-P. FCC Labels and Notices A clearly visible label is required on the outside of the user’s (OEM) enclosure stating that this product contains a DM2200-916VM radio module, FCC ID: TE6-DM2200A. The DM2200-916VM enclosure should be mounted so the antenna is at least 4 feet off the ground, and ideally 6 or more feet off the ground. 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, including interference that may cause undesired operation. The DM2200-916VM has an on-board regulator input on Pin J1-2. To use the on-board regulator, connect J1-3 to J1-2 and apply a voltage to this connection of at least 3.1 Vdc, but not greater than 14 Vdc, including ripple variations. When running from the on-board regulator, up to 5 mA is available on J1-4 to operate external circuitry. Any external circuitry connected to J1-4 must not induce more that 10 mVP-P ripple on the regulated 3 Vdc at this pin. WARNING: This device operates under Part 15 of the FCC rules. Any modification to this device, not expressly authorized by RF Monolithics, Inc., may void the user’s authority to operate this device. DM2200-916VM Applications The DM2200-916VM can also be run from an off-board regulated supply or a battery. In this case, connect J1-3 There are two ways to use the DM2200-916VM in an application. The transceiver module can be used with a to ground, leave J1-2 unconnected, and apply the regucompanion application interface board, the IM2200. The lated supply or battery input to J1-4. Note the input voltage range for J1-4 must be in the range of 2.9 to 3.7 IM2200 has provisions for powering the transceiver module from a USB cable, an external unregulated DC Vdc, with no more than 10 mVP-P ripple. supply such as a 5 Vdc “wall” transformer, an external Only pins J1-2 and J1-3 are rated to operate from a regulated 3 Vdc power supply, or an external battery. supply voltage higher than 3.7 Vdc. Further, care must The IM2200 also provides the choice of UART, RS232, be taken so that analog or logic inputs applied to the RS485 (single drop) or USB for a host computer serial transceiver module stay within the voltage range of 0 to interface. In addition, the IM2200 includes capturedVDD (voltage at J1-4).
