Network Router
Compatible with RFM miniMESHTM Network Protocol
3 V, Very Low Current Operation
Ready-to-Use OEM Module
The DM1800-916MR is the 916.5 MHz router module in the DM1800 family of RF transceivers. The
DM1800 family is designed for adding embedded wireless connectivity to a wide range of monitor-
ing and control systems. This module is compatible with RFM’s miniMESHTM network protocol,
which provides add-on “plug-and-play” multicast mesh network routing. Radio communications
www.DataSheerta4nUg.ecoinman “open field” environment is typically 200 meters/hop. The DM1800-916MR combines
RFM’s very low current ASH radio technology with low power microcontroller technology to achieve
long battery life. The DM1800-916MB is certified for operation under FCC 15.249 regulations.

Theory of Operation
The major components of the DM1800-916MR include
an RFM TR1000 ASH transceiver and a Microchip
PIC16F688 microcontroller. The TR1000 operates on
a frequency of 916.50 MHz, at a nominal output power
of 1 mW. The DM1800 includes two LEDs that indi-
cate the module’s operating mode.
The DM1800-916MR is compatible with RFM’s
miniMESHTM network protocol, which provides add-on
“plug-and-play” mesh network routing to improve com-
munication range and robustness.
DM1800-916MR FCC Certification
The DM1800-916MR hardware has been certified for
operation under FCC Part 15 Rules, Section 15.249.
This certification applies only when a DM1800-916MR
is equipped with one of the following RFM antennas:
helical antenna, RFM part number 500-1195-003
helical antenna, RFM part number 500-1195-103
WARNING: the DM1800-916MR must be re-certified
if used with any antennas other than the two listed
above. Contact RFM for further information if your ap-
plication requires a special antenna configuration.
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 DM1800-916MR transceiver assembly, FCC
ID: TE6-DM1800.
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.
