DM2200-916VM-1 FCC Certification
The DM2200-916VM-1 is certified for operation under
FCC Part 15 Rules, Section 15.247. When the
DM2200-916VM-1 is run from an off-board power
supply (applied to J1-4), the supply voltage must be
limited to a maximum of 3.7 Vdc, and the power
supply voltage ripple must not exceed 10 mV
FCC Labels and Notices
A clearly visible label is required on the outside of the
user’s (OEM) enclosure stating that this product con-
tains a DM2200-916VM-1 radio module, FCC ID:
TE6-DM2200A.
This device complies with Part 15 of the FCC rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference re-
ceived, including interference that may cause unde-
sired operation.
WARNING: This device operates under Part 15 of the
FCC rules. Any modification to this device, not
expressly authorized by RFM, may void the user’s
authority to operate this device.
DM2200-916VM-1 Applications
There are two ways to use the DM2200-916VM-1 in
an application. The transceiver module can be used
with a companion application interface board, the
IM2200. The IM2200 has provisions for powering the
transceiver module from a USB cable, an external
unregulated DC supply such as a 5 Vdc “wall” trans-
former, an external regulated 3 Vdc power supply, or
an external battery. The IM2200 also provides the
choice of UART, RS232, or USB for a host computer
serial interface. In addition, the IM2200 includes cap-
tured-screw terminal strips for connecting analog in-
puts, digital logic inputs, digital logic outputs and form
C relay outputs. Refer to the IM2200 data sheet for
additional details.
The DM2200-916VM-1 can also be integrated into the
user’s own application board. The DM2200-916VM-1
pin descriptions are given in the Table on pages 4 and
5. The transceiver module pin-out locations are show
in Figure 2, and the PCB layout for the mating connec-
tors is shown in Figure 3.

The operating range of the DM2200-916VM-1 de-
pends critically on the antenna being located properly.
When using the standard DM2200-916VM-1 antenna
(part number 400-1687-001), 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. Note: other antenna configurations are
possible, but each new antenna configuration must be
added to the DM2200-916VM-1 FCC module certifica-
tion before deployment. Contact RFM for details.
The DM2200-916VM-1 enclosure should be mounted
so the antenna is at least 4 feet off the ground, and
ideally 6 or more feet off the ground.
The DM2200-916VM-1 has an on-board regulator in-
put on Pin J1-2. To use the on-board regulator, con-
nect J1-3 to J1-2 and apply a voltage to this
connection of at least 3.3 Vdc, but not greater than 14
Vdc, including ripple variations. When running from
the on-board regulator, up to 5 mA is available on J1-4
to operate external circuitry. Any external circuitry con-
nected to J1-4 must not induce more that 10 mV
ple on the regulated 3 Vdc at this pin.
The DM2200-916VM-1 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 mV
ripple.
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
transceiver module 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 module.
The DM2200-916VM-1 has current limiting protection
resistors on most of the I/O pins. These limit the cur-
rent that a logic output can source or sink. Any
DM2200- 916VM 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.
