The DM1810-916MR-V is the 916.5 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 DM1810-916MR-V combines RFM’s very low

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

The DM1810-916MR-V is certified for operation under FCC 15.247 and Canadian RSS 210 regula-

tions.

Theory of Operation

The major components of the DM1810-916MR-V in-

clude an RFM TR8100 ASH transceiver and a Micro-

chip PIC16F689 microcontroller. The TR8100

operates on a frequency of 916.50 MHz, at a nominal

output power of 10 mW. The DM1810-916MR-V in-

cludes two LEDs that indicate the module’s operating

mode.

The DM1810-916MR-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, simplify-

ing commissioning and operating logistics. The firm-

ware 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

web site at www.RFM.com.

DM1810-916MR-V FCC Certification

The DM1810-916MR-V hardware has been certified

for operation under FCC Part 15 Rules, Section

15.247. This certification applies when a DM1810-

916MR-V is equipped with one of the following anten-

nas:

helical antenna, part number 500-1195-204

helical antenna, part number 500-1311-000

The antenna(s) used for this transmitter must be in-

stalled to provide a separation distance of at least

20 cm from all persons and must not be co-located or

operating in conjunction with any other antenna or

transmitter.

FCC Notices and Labels

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 re-

ceived, including interference that may cause unde-

sired operation.

A clearly visible label is required on the outside of the

user’s (OEM) enclosure stating that this product con-

tains a DM1810-916MR-V transceiver assembly, FCC

ID: HSW-DM1810A. WARNING: This device oper-

ates under Part 15 of the FCC rules. Any modification

to this device, not expressly authorized by RFM, may

void the user’s authority to operate this device.

Notice - IC: 4492A-DM1810A

This apparatus complies with Health Canada’s Safety

Code6/ICRSS210. To prevent radio interference to

the licensed service, this device is intended to be

operated indoors and away from windows to provide

maximum shielding. Equipment (or its transmit an-

tenna) that is installed outdoors may be subject to

licensing.

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.
