1. Overview
The XBee/XBee-PRO ZNet 2.5 OEM (formerly known as
Series 2 and Series 2 PRO) RF Modules were engineered to
operate within the ZigBee protocol and support the unique
needs of low-cost, low-power wireless sensor networks.
The modules require minimal power and provide reliable
delivery of data between remote devices.
The modules operate within the ISM 2.4 GHz frequency
band and are compatible with the following:
• XBee RS-232 Adapter
• XBee RS-232 PH (Power Harvester) Adapter
• XBee RS-485 Adapter
• XBee Analog I/O Adapter
• XBee Digital I/O Adapter
• XBee Sensor Adapter
• XBee USB Adapter
• XStick
• ConnectPort X Gateways
• XBee Wall Router.
