XTend® 900MHz RF Modems
Standalone Radio Modems
Serial Cable Extension over Radio Frequency Modem
Extend Serial Cables over the air.
Adjustable power output from 100 mW to 1 W; up to 4 W EIRP (with 6 dB antenna) Digi's XTend-PKG RF modems provide everything you need for out-of-the-box serial cable replacement, enabling quick and inexpensive wireless connectivity of electronic devices across a broad range of applications. Simply feed data into one modem and the data is transported to the other end of a long-range wireless link. Data security is provided by 256-bit AES encryption (128-bit AES is available outside of North America). If more advanced functionality is needed, the modems support an extensive set of AT and binary commands.
Available in multiple interface options, including RS-232/422/485 and USB, XTend modems are ideally suited for remote monitoring, building automation/security, industrial automation/SCADA, fleet management/asset tracking and sensor data capture.

*Range figure estimates are based on free-air terrain with limited sources of interference. The actual range will vary based on transmitting power, the orientation of transmitter and receiver, the height of transmitting antenna, the height of receiving antenna, weather conditions, interference sources in the area, and terrain between receiver and transmitter, including indoor and outdoor structures such as walls, trees, buildings, hills, and mountains.
