WCM802/900
1. SmartStack Wireless
Communication OEM RF Modems
The Horner SmartStack Wireless Communication OEM RF Modems (HE800WCM802 / HE800WCM900 /HE-
WCM802* and HE-WCM900*) are drop-in wireless solutions that transfer a standard asynchronous serial data
stream over-the-air between devices. The Wireless Communication Modems (WCM802 / WCM900) stand out in the
RFd2d (radio frequency device-to-device) segment of the wireless market with their unique combination of high-
performance, ease-of-use and low price
* HE- denotes plastic case version of the SmartStack module instead of the metal case version, which is indicated
by an HE800 prefix in the part number.
Note:
The WCM802 and the WCM900 modules are not compatible with each other and can not be used to
communicate with one another.
