The DM1810 family is designed for adding wireless mesh network connectivity to a wide rangeof monitoring and control systems. The DM1810-916MB is equipped with a serial I/O port to inter-face a host microcontroller. Radio communications range in an “open field” environment is typically600 meters/hop. The DM1810-916MB combines RFM’s very low current ASH radio technology withlow power microcontroller technology to achieve long battery life. This module is compatible withCirronet’s miniMESHTM network protocol, which provides add-on “plug-and-play” multicast meshnetwork routing. The DM1810-916MB is certified for operation under FCC 15.247 and CanadianRSS 210 regulations.•Base Station with Host Serial Interface•Compatible with Cirronet miniMESHTM Network Protocol•3 V, Very Low Current Operation•Ready-to-Use OEM Module
2Theory of OperationThe major components of the DM1810-916MB includean RFM TR8100 ASH transceiver and a MicrochipPIC16F689 microcontroller. The TR8100 operates ona frequency of 916.50 MHz, at a nominal output powerof 10 mW.The 16F689 provides a 9.6 kb/s serial interface forcommunication with a host microcontroller. A compan-ion interface board, the IM1800, is available with USBbridge circuitry to interface the DM1810-916MB to ahost PC. The DM1810 includes two LEDs that indicatethe module’s operating mode.The DM1810-916MB firmware is based on Cirronet’sminiMESH network protocol, which utilizes time-syn-chronized redundant routing to provide robust, deter-ministic packet delivery though a network with up to 15routers. Network configuration and maintenance fea-tures are built into the miniMESH protocol, simplifyingcommissioning and operating logistics. The firmwarealso includes several sleep cycling methods for ex-tended battery life operation.Please refer to the DM1810 User’s Guide and theAN1810 series Application Notes for installation andapplication programming information.

The allowed input voltage range is 2.6 to 10 V.J1-3 VOUTVOUT tracks 50 to 100 mV below VIN when VIN is in the range of 2.6 to 3.1 V. When VIN is in the range of 3.1to 10 V, VOUT is regulated at 3.0 Vdc. Up to 10 mA can be supplied from this pad for powering external circuitssuch as thermistor-resistor networks. External circuitry must not impress more than 10 mVp-p ripple on the regu-lated output voltage.J1-4 BINDThis pad is connected to a logic input on the microcontroller, and is configured with a weak pull-up. When thispin is momentarily grounded to J1-1 or J1-10, the module is placed into the bind mode, allowing this module tobe associated with other modules to form a network.J1-5 - This pad is unused in base station operation. Leave this pad electrically unconnected.J1-6 - This pad is unused in base station operation. Leave this pad electrically unconnected.J1-7 - This pad is unused in base station operation. Leave this pad electrically unconnected.J1-8 SERIAL RXThis pad is connected to the module’s serial data input (USART). Data to this pin is received at 9.6 kb/s, using8 data bits, no parity, and one stop bit. The input voltage range on this pad is 0 to VOUT. Applying a voltageoutside of this range may damage the module.J1-9 SERIAL TX This pad is connected to the module’s serial data output (USART) through a 1 kilohm resistor, which providesshort-circuit protection. Data from this pad is sent at 9.6 kb/s, using 8 data bits, no parity, and one stop bit.J1-10 GND This pad is a signal and power supply ground.J3-1 GND This pad is a ground for the antenna port.J3-2 ANT This pad is the antenna port.J3-3 GND This pad is a ground for the antenna port.J4-1 D1 This pad is the LED 1 signal.J4-2 D2 This pad is the LED 2 signal.CAUTION: Electrostatic Sensitive Device.
