Remotely Restart Four Devices
A standard dial-up voice telephone line can be used to remotely power-off and power-on devices. Using a PC with almost any serial data client software such as HyperTerminal (tm), an remote user can individually control up to four receptacles.
This device is useful for retail stores or kiosks where electronic devices need occasional rebooting from a remote location. The total current and individual consumed by the four receptacles is reported along with the voltage. The unit can be ordered with 1,2,3 or 4 receptacles.
Each Power Controller and each receptacle can be give a friendly name. Each Controller is factory assigned a unique 64 bit address at time of manufacture.
Two levels of password protection are provided: four users and an administrator. The user password permits power cycling and the administrator can assign privileges to each user. Each user can be assigned rights to control any given set of receptacles, or all receptacles.
