Digi International Inc XBEEPRO2 Manual Do Utilizador

The XBee/XBee-PRO modules have a 2x5 SIF header that can be used with Ember's InSight tools to upload 
firmware onto the modules. These tools include a USB device (USBLink) and Ethernet-enabled InSight Adapters. 
Contact Ember for details.

Warning: If programming firmware through the SIF interface, be aware that uploading firmware through the 
SIF header can potentially erase the XBee bootloader. If this happens, serial firmware updates will not work.

(The pinout for the SIF headers are shown in chapter 1.)

The XBee/XBee-PRO module can be used as a hardware development platform for the EM250. Custom firmware 
images can be developed around the EmberZNet 2.5.x and 3.x mesh stacks (for the EM250) and uploaded to the 
XBee.

Warning: If programming firmware through the SIF interface, be aware that uploading firmware through the SIF 
header can potentially erase the XBee bootloader. If this happens, serial firmware updates will not work.

XBee modules are FCC and ETSI certified for operation on all 16 channels. The EM250 output power can be 
configured up to 3dBm with boost mode enabled.

XBee-PRO modules are certified for operation on 14 of the 16 band channels (channels 11 - 24). The scan 
channels mask of XBee-PRO devices must be set in the application to disable the upper two channels (e.g. 
0x01FFF800). The XBee-PRO contains power compensation circuitry to adjust the output power near 18dBm or 
10dBm depending on the part number. For best results, the EM250 should be configured with an output power 
level of 0dBm (or -2dBm if boost mode is enabled). The end product is responsible to adhere to these 
requirements. 

Most of the remaining sections in this chapter describe how to configure GPIO 1 and 2 to function correctly in 
custom applications that run on the XBee and XBee-PRO modules. In order for GPIO pins 1 and 2 to be 
configurable, the application must set the GPIO_CFG register to enable GPIO 1 and 2. Bits 4 - 7 in the 
GPIO_CFG register control the functionality of various GPIO lines. The following table lists values for these bits 
that enable GPIO 1 and 2. Other functionality is affected by these settings. See the EM250 datasheet from 
Ember for a complete listing of functionality.
