如何购买 支持

When you need to punch through noisy environments and cover long distances, Digi XBee® SX 1-Watt 900 MHz RF modems provide a combination reliability and redundancy for integrators building low-power, mission-critical wireless systems. With interface options including RS232/485 or Digital/ Analog I/O, these modems utilize the DigiMesh® wireless networking protocol, with redundant mesh network operation and support for low-power sleeping nodes.

Customers that don’t require mesh network architecture can configure the modem to operate in simple point to multipoint mode. With ideal RF line-of-sight range estimated up to 65 miles*** and strong interference blocking, these modems are ideal for applications requiring a reliable, redundant wireless cable replacement over longer ranges.

The Digi XBee SX modems can be configured easily via the USB port, using Digi’s free XCTU software. They are precertified for use in multiple countries and provide secure, reliable delivery of critical data between devices with 256-bit AES encryption.

* We estimate rural ranges based on a 14.5 km (9 mi) range test with dipole antennas.
**Range estimated assuming that the urban noise floor is approximately 15 dB higher than rural. The actual range depends on the setup and level of interference in your location.
***Range figure estimates are based on free-air terrain with limited sources of interference. Actual range will vary based on transmitting power, orientation of transmitter and receiver, height of transmitting antenna, 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.
