The DM1800-434MR-PAH and DM1800-434MR-PBH are 434.92 MHz packaged router modules
designed for indoor horizontal mounting. The modules are part of the DM1800 family of RF trans-
ceivers. The DM1800 family is designed for adding wireless mesh connectivity to a wide range of
monitoring and control systems. These modules are also compatible with RFM’s miniMESH
TM
net-
work protocol, which provides “plug-and-play” multicast mesh network routing. Radio communica-
tions 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 battery life. The DM1800-434MR-PAH and DM1800-434MR-PBH contain a DM1800-434MR
router. The DM1800-434MR is certified for operation under ETSI I-ETS 300 220.

Theory of Operation
The DM1800-434MR-PAV and DM1800-434MR-PBV
are packaged versions of the DM1800-434MR router.
The major components in these modules include an
RFM TR3000 ASH transceiver and a Microchip
PIC16F688 microcontroller. The TR3000 operates on
a frequency of 433.92 MHz, at a nominal output power
of 1 mW. The DM1800-434MR includes two LEDs that
indicate the module’s operating mode.
The DM1800-434MR 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 7 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
DM1800 User’s Guide
and the
AN1800 series Application Notes
for installation and
application programming information. See Cirronet’s
web site at www.Cirronet.com.
The DM1800-434MR-PAV includes a wall plug trans-
former power supply.
The DM1800-434MR-PBV includes a battery pack
power supply.
