RF modules

A radio frequency (RF) module is a small electronic circuit used to transmit and receive radio signals on different frequencies. Digi produces a wide variety of RF modules to meet the requirements of almost any wireless solution, such as long-range, low-cost, and low-power modules. The most popular wireless products are the XBee RF modules.

XCTU is compatible with Digi's XBee and XTend RF modules and XLR PRO. For a complete list of XCTU-compatible modules, see XCTU requirements.

XBee RF modules

XBee is the brand name of a family of RF modules produced by Digi. They are modular products that make deploying wireless technology easy and cost-effective. Digi has made multiple protocols and RF features available in the popular XBee footprint, giving customers enormous flexibility to choose the best technology for their needs.

XBee RF modules are available in two form-factors, Through-Hole and Surface Mount, with different antenna options. One of the most popular features of these modules is that almost all of them are available in the Through-Hole form factor and share the same footprint.

XTend RF modules

XTend family devices are long-range RF modules produced by Digi that provide unprecedented range in a low-cost wireless data solution. They were engineered to provide customers with an easy-to-use RF solution that provides reliable delivery of critical data between remote devices. These modules transfer standard asynchronous serial data streams, operate within the ISM 900 MHz frequency band, and sustain up to 115.2 Kbps data throughput.

XLR PRO radio solutions

The XLR PRO is an ultra long-range, rugged 900MHz radio solution designed for optimal performance even in the most challenging RF environments. Leveraging Digi's patent-pending Chirp Spread Spectrum technology, the XLR PRO provides industry-leading receive sensitivity and interference immunity, making it ideal for deployments in noisy RF environments like oil fields. The XLR PRO includes 2 Ethernet ports and 1 serial port, enabling wireless data communications between Ethernet and/or serial devices up to distances of over 90 miles.
