XTend®900MHz 射频调制解调器

1 瓦/900 兆赫独立无线电调制解调器

 
  • 室外视距可达 40 英里*(使用高增益天线)
  • 出色的接收器灵敏度(-110 dBm @9600 bps)

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.

*范围数字估计基于干扰源有限的自由空气地形。实际距离会因发射功率、发射器和接收器的方向、发射天线的高度、接收天线的高度、天气条件、区域内的干扰源以及接收器和发射器之间的地形(包括墙壁、树木、建筑物、丘陵和山脉等室内外结构)而有所不同。
