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 radiotechnology with low-power microcontroller technology to achieve long battery life. The CX2200 iscompatible 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 underFCC 15.249 regulations.•Base Station or Router Capability•Compatible with RFM miniMESHTM Network Protocol•3 V, Very Low Current Operation•Ready-to-Use Assembly
2Theory of OperationThe major components of the CX2200 transceiver as-sembly include the CM2200 transceiver module andthe CI2200 interface module. The CM2200 includes aTR1000 ASH transceiver and a Microchip 16LF876Amicrocontroller. The TR1000 operates on a frequencyof 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 theCM2200 circuit board. The CM2200 also includesthree LEDs that indicate the transceiver’s operatingmodes.The CI2200 provides a choice of RS232 or USB to in-terface to a host computer. USB drivers for varioushost computer operating systems can be obtained atwww.silabs.com (CP2101). The CI2200 also providesregulated 3 Vdc for operating its circuitry and theCM2200 transceiver module. The positions of theset-up jumper blocks for RS232 operation are shownin Figure 2, and the positions of the set-up jumperblocks for USB operation are shown in Figure 3.RS232 operation requires external power, which is in-put on connector J4. The CX2200 is powered directlyfrom the USB connector when using the USB inter-face. There are two LEDs on the CI2200 interfacemodule. LED D1 indicates that regulated 3 Vdc ispresent, and the LED D2 indicates an active USBconnection.The CX2200 is compatible with RFM’s miniMESHTMnetwork protocol, which provides add-on “plug-and-play” multicast mesh network routing to improve com-munication range and robustness.FCC Labels and NoticesThis 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.A clearly visible label is required on the outside of theuser’s (OEM) enclosure stating that this product con-tains a CX2200 transceiver assembly, FCC ID: TE6-CX2200.WARNING: This device operates under Part 15 of theFCC rules.
