The DM2100 is a 916.5 MHz transceiver module designed for wireless industrial sensor applications. The DM2100 is equipped with seven I/O ports. Each port can be configured as an analog
input, a digital input, or a digital output. The DM2100 is also equipped with a serial data port. The
communication range of the DM2100 in an “open field” environment is typically 200 meters/hop.
The DM2100 combines RFM’s low-current ASH radio technology with low-power microprocessor
technology to achieve very long battery life. The DM2100 employs NOKOTA’s SOS-OEA V1.5
multi-mode mesh network protocol, which provides robust and flexible wireless network routing, a
rich application command set, and a powerful and easy-to-use network management utility. The
DM2100 is certified under FCC 15.249 regulations.

network as a logic input, a logic output, or an analog

RF communication activity.
The MSP430F148 UART is used to provide a CMOS
serial interface on connector J2. The microcontroller’s
general purpose I/O pins are also available on connector J2 for external monitoring or control. Each of
DM2100 operation is based on NOKOTA’s SOS-OEA
V1.5 multi-mode mesh network protocol, which supports data and command transfers through both the serial interface and the RF channel. See the SOS-OEA
V1.5 Protocol User’s Guide for further details.
DM2100 FCC Certification
The DM2100 can also be integrated into the user’s own
application board. The DM2100 pin descriptions are
given in the Table on pages 4 and 5. The DM2100
pin-out locations are show in Figure 2, and the PCB layout for the mating connectors is shown in Figure 3.
The DM2100 has been certified for operation under
FCC Part 15 Rules, Section 15.249. This certification
applies only when the DM2100 is equipped with one of
the following RFM antennas:
The operating range of the DM2100 critically depends
on the antenna being located properly. When using either the 400-1595-001 or the 500-1141-001 antenna,
care should be taken to keep the antenna at least 0.5
inch away from the sides of its enclosure. The enclosure must be made from a plastic with low RF attenuation, such as fiberglass, PVC or ABS. For a metal
enclosure, use the 500-1142-001 antenna-coax assembly, with the antenna mounted on the outside of the enclosure. Note that a reverse-pin SMA connector must
be installed on the DM2100 to use this assembly.

helical antenna, RFM part number 500-1141-001
¼ wave antenna-coax assembly, RFM part number 500-1142-001
WARNING: the DM2100 must be re-certified if used
with any antennas other than the three listed above.
Contact RFM for further information if your application
requires a special antenna configuration.

to a maximum of 3.7 Vdc, and the power supply voltage The DM2100 enclosure should be mounted so the anripple must not exceed 10 mVP-P.

tion.
WARNING: This device operates under Part 15 of the
FCC rules. Any modification to this device, not expressly authorized by RF Monolithics, Inc., may void
the user’s authority to operate this device.
The DM2100 can also be run from an off-board regulated supply or a battery. In this case, connect J1-3 to
ground, leave J1-2 unconnected, and apply the regulated supply or battery input to J1-4. Note the input voltage range for J1-4 must be in the range of 2.9 to 3.7
Vdc, with no more than 10 mVP-P ripple.
DM2100 Applications
There are two ways to use the DM2100 in an application. The DM2100 can be used with a companion application interface board, the IM2100. The IM2100 has
provisions for powering the DM2100 from a USB cable,
an external unregulated DC supply such as a 5 Vdc
“wall” transformer, an external regulated 3 Vdc power
supply, or an external battery. The IM2100 also provides the choice of UART, RS232, RS485 (single drop)
or USB for a host computer serial interface. In addition,
the IM2100 includes captured-screw terminal strips for
connecting analog inputs, digital logic inputs, digital
logic outputs and form C relay outputs. Refer to the
IM2100 data sheet for additional details.
Only pins J1-2 and J1-3 are rated to operate from a
supply voltage higher than 3.7 Vdc. Further, care must
be taken so that analog or logic inputs applied to the
DM2100 stay within the voltage range of 0 to VDD (voltage at J1-4). Applying a voltage outside of the 0 to VDD
voltage range to an analog or logic input can damage
the DM2100.
The DM2100 has current limiting protection resistors on
most of the I/O pins. These limit the current that a logic
output can source or sink. Any DM2100 pin defined as
an output should be used only to drive a high impedance load such as a CMOS logic input or a MOSFET
transistor.

Pin
Name
Description
J1-1
GND
This pin is connected to ground.
J1-2
VIN
This pin is the input to the DM2100 on-board voltage regulator. The minimum input voltage to this pin is 3.1 V,
and the maximum input to this pin is 14.0 V.
J1-3
VREN
This pin is the enable input for the DM2100 on-board regulator. To enable the on-board regulator, connect this
pin to J1-2. To disable the on-board regulator, connect this pin to ground.

VDD
This pin is connected to the DM2100 positive power supply buss. When the DM2100 is powered from the
on-board regulator, this pin can provide up to 5 mA of current at 3.0 Vdc. Note this current adds to the receive,
transmit and sleep currents listed in the specifications on Page 1. The external load must not impress more
than 10 mV peak -peak ripple on the supply buss. If the on-board regulator is disabled, the DM2100 can be
powered through this pin by an external 2.85 to 3.7 Vdc source (maximum ripple 10 mV peak-peak).
