Transceiver
Assembly
The CX2200 is a 916.5 MHz transceiver assembly designed for base station and router applications
in wireless industrial sensor networks. The communications range of the CX2200 in an “open field”
environment is typically 200 meters/hop. The CX2200 combines RFM’s very low-current ASH radio
technology with low-power microcontroller technology to achieve long battery life. The CX2200 is
compatible with RFM’s miniMESHTM network protocol, which provides add-on “plug-and-play”
multicast mesh network routing. The CX2200 transceiver assembly is certified for operation under
FCC 15.249 regulations.

Theory of Operation
The major components of the CX2200 transceiver as-
sembly include the CM2200 transceiver module and
the CI2200 interface module. The CM2200 includes a
TR1000 ASH transceiver and a Microchip 16LF876A
microcontroller. The TR1000 operates on a frequency
of 916.5 MHz, at a nominal output power of 0.5 mW.
The CM2200 includes an insulated wire antenna,
which should be set straight and perpendicular to the
CM2200 circuit board. The CM2200 also includes
three LEDs that indicate the transceiver’s operating
modes.
The CI2200 provides a choice of RS232 or USB to in-
terface to a host computer. USB drivers for various
host computer operating systems can be obtained at
www.silabs.com (CP2101). The CI2200 also provides
regulated 3 Vdc for operating its circuitry and the
CM2200 transceiver module. The positions of the
set-up jumper blocks for RS232 operation are shown
in Figure 2, and the positions of the set-up jumper
blocks for USB operation are shown in Figure 3.
RS232 operation requires external power, which is in-
put on connector J4. The CX2200 is powered directly
from the USB connector when using the USB inter-
face. There are two LEDs on the CI2200 interface
module. LED D1 indicates that regulated 3 Vdc is
present, and the LED D2 indicates an active USB
connection.
The CX2200 is compatible with RFM’s miniMESHTM
network protocol, which provides add-on “plug-and-
play” multicast mesh network routing to improve com-
munication range and robustness.
FCC Labels and Notices
