TE6-DM2200ARemote Transceiver Module

1 ® DM2200- 916VM The 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 digital outputs 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 radio technology with low-power microprocessor technology to achieve very long battery life. The DM2200-916VM employs RFM’s VersaMESH TM 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.

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 kHz or 6 MHz crystal. The MSP430F148 UART is used to provide a CMOS serial interface on connector J2. The microcontroller’s I/O pins are also available on connector J2 for external 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. DM2200-916VM operation is based on RFM’s multi- tasking VersaMESH TM network protocol, which supports data and command transfers through both the serial in - terface and the RF channel. See theVersaMESH TM Pro - tocol User’s Guidefor further details. 2 56789104321 GNDVIN 11121314 VRENVDDTD0TD1TWSTCKRSTCFG0CFG1CFG2CFG3GND J1 1 2 3 4 5 6 7 8 9 10 11 12 13 14 J2 3 VDC GRN YEL RED TR8100 ASH Transceiver RSSI Low Voltage Reset TXMOD RXDATA CFGDAT CFGCLK 3 VDC Voltage Regulator DM2200 Block Diagram GND GP7 GP6 GP5 GP4 GP3 GP2 GP1 GP0/RSSI RTS CTS TXD RXD GND MSP430F148 Microcontroller CFG Figure 1 DM2200-916VM FCC Certification 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 mV P-P . FCC Labels and Notices A clearly visible label is required on the outside of the user’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 the FCC rules. Any modification to this device, not ex- pressly authorized by RF Monolithics, Inc., may void the user’s authority to operate this device. DM2200-916VM Applications There are two ways to use the DM2200-916VM in an application. The transceiver module can be used with a companion application interface board, the IM2200. The IM2200 has provisions for powering the transceiver module from a USB cable, an external unregulated DC supply such as a 5 Vdc “wall” transformer, an external regulated 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 serial interface. In addition, the IM2200 includes captured- screw terminal strips for connecting analog inputs, digi - tal logic inputs, digital logic outputs and form C relay outputs. Refer to the IM2200 data sheet for additional details. The DM2200-916VM can also be integrated into the user’s own application board. The DM2200-916VM pin descriptions are given in the Table on pages 4 and 5. The transceiver module pin-out locations are show in Figure 2, and the PCB layout for the mating connectors is shown in Figure 3. 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 enclosure should be mounted so the antenna is at least 4 feet off the ground, and ideally 6 or more feet off the ground.…
