Computer Controlled Switching from
Anywhere on the Network
Wi-Fi 802.11b relay allow computer controlled switching from any computer connected to a wireless internet access point. A Wi-Fi 802.11 relay Controller must be within range of an internet hot spot, allowing computer controlled switching from anywhere on the network.
Summary of Wi-Fi Communications

Communications and software development is very easy, simply write your software to speak to the RS-232 serial port (COM port of your PC), and install the included RealPort Drivers that allow you to map a COM port to an I.P. address. So you do not have to know anything about Wi-Fi 802.11b communications to speak to the device.
Many Communication Protocols for Advanced Users
Advanced users may want to employ other communication protocols to speak the the Wi-Fi 802.11b Relay Controller. NCD Wi-Fi 802.11b Relay Controllers can also be controlled using Telnet. I.P. Addresses and are automatically or manually assigned. NCD Ethernet Relay Controllers Aaso support security protocols such as Shared Key, WEP, WPA, and Cisco LEAP with support for WEP, TKIP, and CCMP Data Encryption.
UXP is a new standardized data port, specifically for the purpose of speaking to various expansion modules. If the controller you are considering is equipped with a UXP port, you can take advantage of extended commands to speak to our growing line of I/O expansion modules. UXP in the part number allows you to:
