Operating channels

The XBee/XBee-PRO S2C DigiMesh 2.4 operates over the 2.4 GHz band using direct sequence spread spectrum (DSSS) modulation. DSSS modulation allows the device to operate over a channel or frequency that you specify.

The 2.4 GHz frequency band defines 16 operating channels. XBee devices support all 16 channels and XBee-PRO devices support 12 of the 16 channels.

Use the CH command to select the operating channel on a device. CH tells the device the frequency to use to communicate.

For devices to communicate, the CH and ID commands must be equal on all devices in the network.

Note these requirements for communication:

• A device can only receive data from other devices within the same network (with the same ID value) and using the same channel (with the same CH value).
• A device can only transmit data to other devices within the same network (with the same ID value) and using the same channel (with the same CH value).
