Theory of Operation
The major components of the DM1810-916MN 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 DM1810-916MN to a
host PC. Three of the 16F689 I/O pins are configured
for external monitoring or control. Digital In is config-
ured as a logic input with a weak pull-up for sensing a
contact closure to a ground pad. Digital Out is config-
ured a logic output. Analog In is configured as a 10-bit
analog-to-digital input. The DM1810 includes two
LEDs that indicate the module’s operating mode.
The DM1810-916MN firmware is based on Cirronet’s
miniMESH network protocol, which utilizes time-syn-
chronized redundant routing to provide robust, deter-
ministic packet delivery though a network with up to 15
routers. Network configuration and maintenance fea-
tures are built into the miniMESH protocol, simplifying
commissioning and operating logistics.
The DM1810-916MN application programming inter-
face (API) provides straightforward, flexible support for
the serial port, ADC input, digital input and digital out-
put, including event messaging from field nodes. The

firmware 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 Cirronet’s
