Digi XTend-PKG-R

900Mhz UHF/VHF radio modem

Part # 93704-01

Digi XTend 900Mhz UHF/VHF radio modem

Digi's XTend-PKG 900 MHz (1 Watt) radio modem provide everything you need for out-of-the-box serial cable replacement, enabling quick wireless connectivity of data loggers, sensors, or complete environmental monitoring systems.

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, and with an optional NEMA 4-rated enclosure, XTend modems are ideally suited for remote monitoring, building automation/security, industrial automation/SCADA, fleet management/asset tracking and sensor data capture.

  • Indoor/Urban range of up to 3000 feet (900 m)
  • Outdoor line-of-sight range of up to 40 miles (64 km) with high-gain antenna
  • Adjustable power output from 1 mW to 1W; up to 4 W EIRP (with 6 dB antenna)
  • Low power consumption for power-sensitive applications - pin, serial port, and cyclic sleep modes available
  • Durable industrial-grade enclosure
