module
About the XTCRF module
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, Canada, Australia
and other countries.
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.
