DM1810-
916MR-V
• Network Router
• Compatible with RFM miniMESHTM Network Protocol
• 3 V, Very Low Current Operation
• Ready-to-Use OEM Module
916.50 MHz
Transceiver
Module
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
916MR-V is equipped with one of the following anten-
nas:
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.
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.
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.
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

Description
This pad is a signal and power supply ground.
This is the power supply input pad. The allowed input voltage range is 2.6 to 10 V.
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.

VOUT
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.
