Base Station with Host Serial Interface
Compatible with RFM miniMESHTM Network Protocol
3 V, Very Low Current Operation
Ready-to-Use OEM Module
The DM1800-434MB is the 433.92 MHz base station module in the DM1800 family of RF transceiv-
ers. The DM1800 family is designed for adding embedded wireless connectivity to a wide range of
monitoring and control systems. The DM1800-434MB is equipped with a serial I/O port to interface
to a host microcontroller. The module also includes an analog input, a logic input, and a logic output
www.DataSheefto4rUlo.ccoaml monitoring and control. Radio communications range in an “open field” environment is typi-
cally 200 meters/hop. The DM1800-434MB combines RFM’s very low current ASH radio technology
with low power microcontroller technology to achieve long battery life. This module is compatible
with RFM’s miniMESHTM network protocol, which provides add-on “plug- and-play” multicast mesh
network routing. The DM1800-434MB is designed for operation under ETSI I-ETS 300 220 regula-
tions.

DM1800-434MB I/O Pad Descriptions
Pin Name
Description
J1-1
GND
This pad is a signal and power supply ground.
J1-2 VIN This is the power supply input pad. The allowed input voltage range is 2.6 to 14 V.
VOUT tracks 50 to 100 mV below VIN when VIN is in the range of 2.6 to 3.1 V. When VIN is in the range of 3.1
J1-3
VOUT
to 14 V, VOUT is regulated at 3.0 Vdc. Up to 10 mA can be supplied from this pad for powering external circuits
such as thermistor-resistor networks. External circuitry must not impress more than 10 mVp-p ripple on the regu-
lated output voltage.
This pad is connected to a logic input on the microcontroller, and is configured with a weak pull-up. When this pin
J1-4
BIND
is momentarily grounded (to J1-1 or J1-10, the module is placed into the bind mode, allowing this module to be
associated with other modules to form a network.

J1-5
DIGITAL IN
This pad is connected to a logic input on the microcontroller, and is configured with a weak pull-up, allowing
both logic signals and contact closures referenced to J-1 or J-10 to be read. The value of this input is sent over
the RF channel as a response to an RF command. The input voltage range on this pad is 0 to VOUT. Applying
a voltage outside of this range may damage the module.
This pad in the input to the microcontroller’s 10-bit analog-to-digital (ADC) converter. The ADC input range is 0
J1-6
ANALOG IN
to VOUT, referenced to J1-1 or J1-10. The input voltage range on this pad is 0 to VOUT. Applying a voltage
outside of this range may damage the module. The ADC reading is sent over the RF channel as a response to
an RF command.
This pad is connected to a logic output on the microcontroller through a 1 kilohm resistor, which provides
J1-7 DIGITAL OUT short-circuit protection. The value of this output is set or read over the RF channel as a response to an RF com-
mand.
This pad is connected to the module’s serial data input (USART). Data to this pin is received at 9.6 kb/s, using
J1-8 SERIAL RX 8 data bits, no parity, and one stop bit. The input voltage range on this pad is 0 to VOUT. Applying a voltage
outside of this range may damage the module.
J1-9
SERIAL TX
This pad is connected to the module’s serial data output (USART) through a 1 kilohm resistor, which provides
short-circuit protection. Data from this pad is sent at 9.6 kb/s, using 8 data bits, no parity, and one stop bit.
J1-10
GND
This pad is a signal and power supply ground.
J2-1
GND
This pad is a ground for the antenna port.
J2-2
ANT
This pad is the antenna port.
J2-3
GND
This pad is a ground for the antenna port.
