The DM1810-434MR-V is the 433.92 MHz router module in the DM1810 family of RF transceivers.

The DM1810 family is designed for adding wireless mesh connectivity to a wide range of monitor-

ing and control systems. This module is compatible with RFM miniMESHTM network protocol, which

provides “plug-and-play” multicast mesh network routing. Radio communications range in an “open

field” environment is typically 600 meters/hop. The DM1810-434MR-V combines RFM’s very low

current ASH radio technology with low power microcontroller technology to achieve long battery life.

The DM1810-434MR-V is certified for operation under ETSI I-ETS 300 220 regulations.

Theory of Operation

The major components of the DM1810-434MR-V

include an RFM TR7000 ASH transceiver and a Micro-

chip PIC16F689 microcontroller. The TR7000 oper-

ates on a frequency of 433.92 MHz, at a nominal

output power of 10 mW. The DM1810-434MR-V in-

cludes two LEDs that indicate the module’s operating

mode.

The DM1810-434MR-V firmware is based on RFM’s

miniMESH network protocol, which utilizes time-

synchronized redundant routing to provide robust,

deterministic packet delivery though a network with up

to 15 routers.

Network configuration and maintenance features are

built into the miniMESH protocol, simplifying commis-

sioning and operating logistics. The firmware also

includes several sleep cycling methods for extended

battery life operation.

Please refer to the DM1810 User’s Guide and the

AN1810 series Application Notes for installation and

application programming information. See the RFM

Pin Name Description

J1-1 GND This pad is a signal and power supply ground.

J1-2 VIN This is the power supply input pad. The allowed input voltage range is 2.6 to 10 V.

J1-3 VOUT

VOUT 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 3.1

to 10 V, VOUT is regulated at 3.0 Vdc. Up to 10 mA can be supplied from this pad for powering external circuits

such as thermistor-resistor networks. External circuitry must not impress more than 10 mVp-p ripple on the regu-

lated output voltage.

J1-4 BIND

This pad is connected to a logic input on the microcontroller, and is configured with a weak pull-up. When this

pin is momentarily grounded to J1-1 or J1-10, the module is placed into the bind mode, allowing this module to

be associated with other modules to form a network.

J1-5 - This pad is unused in router operation. Leave this pad electrically unconnected.

J1-6 - This pad is unused in router operation. Leave this pad electrically unconnected.

J1-7 - This pad is unused in router operation. Leave this pad electrically unconnected.

J1-8 - This pad is unused in router operation. Leave this pad electrically unconnected.

J1-9 - This pad is unused in router operation. Leave this pad electrically unconnected.

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.
