XBee®/XBee-PRO XTend Compatible (XTC) DigiMesh
RF Module User Guide
The XBee/XBee-PRO XTend Compatible (XTC) RF module provides a radio frequency (RF) solution for
the reliable delivery of critical data between remote devices. It is a 30 dBm (1 Watt) long-range
original equipment manufacturer (OEM) device. We also offer a low power version of this module that
offers transmit power adjustable up to 13 dBm.
The XTC module uses Frequency Hopping Spread Spectrum (FHSS) agility to avoid interference by
hopping to a new frequency on every packet transmission or re-transmission. Its transmit power is
software adjustable up to 30 dBm, which is the maximum output power allowable by governments
that use 900 MHz as a license-free band. The XTC module is approved for use in the United States and
Canada.
The XTC transfers a standard asynchronous serial data stream, operates within the ISM 900 MHz
frequency band and offers two RF data rates of 10 kb/s and 125 kb/s.
As the name suggests, the XTC is over-the-air compatible with Digi's XTend module. The XTC is not a
drop-in replacement for the XTend. If you require form factor compatibility, you must use the XTend vB
RF Module.
For new applications, we recommend that you use the XBee/XBee-Pro SX module. It uses the same
hardware as the XTC but we optimize the firmware for the best range and interference immunity.
However, it is not over-the-air compatible with the XTend.
