Theory of Operation
The major components of the DM1810-916MB include
an RFM TR8100 ASH transceiver and a Microchip
PIC16F689 microcontroller. The TR8100 operates on
a frequency of 916.50 MHz, at a nominal output power
of 10 mW.
The 16F689 provides a 9.6 kb/s serial interface for
communication with a host microcontroller. A compan-
ion interface board, the IM1800, is available with USB
bridge circuitry to interface the DM1810-916MB to a
host PC. The DM1810 includes two LEDs that indicate
the module’s operating mode.
The DM1810-916MB 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
