XBee-PRO XSC RF Module overview
The XBee-PRO XSC RF Modules are engineered to afford integrators with an easy-to-use RF solution
that provides reliable delivery of critical data between remote devices. These modules come
configured to sustain reliable long-range wireless links. The XBee-PRO XSC RF Module is a drop-in
wireless solution that transfers a standard asynchronous serial data stream.
The S3 hardware variant is a legacy design that is obsolete. New and old designs should use the S3B
hardware variant, which features better performance, lower current draw, and is backward
compatible with and a direct replacement for S3 radios. The S3B hardware with XSC firmware is also
fully backward compatible (serial interface and over-the-air) with the 9XStream radios.
Pin signals
The following table shows the pin signal descriptions. Low-asserted signals are distinguished with a
horizontal line over the signal name.

(DataOut)
O N/A Serial data exiting the module (to the UART host); See UART-
interfaced data flow.
3 DI (Data In I N/A Serial data entering the module (from UART host). See UART-
interfaced data flow.

O High Pin is driven high during RF data reception; otherwise, the pin
is driven low. See CD (DO3 Configuration) to enable.
5 RESET

I/O Low Re-boot module (minimum pulse is 90 µs). Open Drain
configuration. Module drives reset line low momentarily on
reboot and power up.
6 CONFIG

I Low / high Pin can be used as a backup method for entering Command
Mode during power-up. Primary method is with +++. See AT
commands for more information.
7 O Driven high Do not connect
