The DM1800-916MR-PAH and DM1800-916MR-PBH are 916.5 MHz packaged router modules de-
signed for indoor horizontal mounting. The modules are part of the DM1800 family of RF transceiv-
ers. The DM1800 family is designed for adding wireless mesh connectivity to a wide range of
monitoring and control systems. These modules are compatible with RFM’s miniMESH
TM
network
protocol, which provides “plug-and-play” multicast mesh network routing. Radio communications
range in an “open field” environment is typically 200 meters/hop. The modules combine RFM’s very
low current ASH radio technology with low power microcontroller technology to achieve long bat-
tery life. The DM1800-916MR-PAH and DM1800-916MR-PBH contain a DM1800-916MR router,
which is module certified for operation under FCC 15.249 regulations.

Theory of Operation
The DM1800-916MR-PAH and DM1800-916MR-PBH
are packaged versions of the DM1800-916MR router.
The major components in these modules 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. Two LEDs, visible through a view port, indi-
cate the router’s operating mode.
The DM1800-916MR-PAH and DM1800-916MR-PBH
are compatible with RFM’s miniMESH
TM
network pro-
tocol, which provides add-on “plug-and-play” mesh
network routing to improve communication range and
robustness.
The DM1800-916MR-PAH includes a wall plug trans-
former power supply.
The DM1800-916MR-PAH includes a battery pack
power supply.
FCC Certification
The DM1800-916MR-PAH and DM1800-916MR-PBH
hardware have been certified for operation under FCC
Part 15 Rules, Section 15.249.
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-PAH or DM1800-916MR-PBH
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 RFM, may void the user’s au-
thority to operate this device.
