The PC controlled USB-Switch 3,5" turns devices with up to 30V / 3A operating voltage on and off. Devices are connected with mono jack. By using of an extremely Finder®Relay it is possible to operate devices with inductive load. For example the USB Switch 3,5" controls ringing bells, playtrains, etc.

With our software ClewareControl the switch also can be used as a time switched clock with different repetition intervals. Apart from starting and end-time also time intervals or weekdays can be choosed as circuit criterion.

The USB Switch 3,5" can be configured by software in such way, after switching on the PC he activated the power (ATSX). The configuration is reversible. The device may be reconfigured by the user to act as an USB-Switch 3,5" or USB- Switch ATXX.

The size of the switch is about 55 x 85 x 80 mm. A mono jack is located in the short side of the switch. On top a LED is located to indicate the switch state. The LED is red if the switch is off and it will turn to green if the switch is on.

The USB-Switch should be operated in inner rooms only and should be protected against humidity. The permissible operating temperature range is 10° - 60° Celsius.

About 32 switches may be connected to a PC using several HUBs. The HUBs used must use a separate power supply. When using Cleware USB devices it is not neccessary to install device drivers. The standard USB drivers are sufficient. So the system stability will not be harmed.

The USB-Switch 3,5" will be delivered with the software ClewareControl for displaying and switching. For easy access a very simple graphical program called USBswitch controls the switch just by clicking on icons. And for integration in batch programs, a command line tool USBswitchCMD is available. The software is running with Windows® 98, Windows® 98 SE, Windows® ME, Windows® 2000, Windows® XP and Windows® .NET. (® Microsoft Windows is a registered trademark of the Microsoft Corporation).

The software ClewareControl may turn the USB-Switch 3,5" into a time switch. Different repeat interval, start and end times may be specified. Some very interesting applications could be created with the combination of an USB-Switch 3,5"with an USB-Temp sensor. The software ClewareControl will then turns the USB-Switch 3,5" on and off in direct reaction of the temperature measured by the sensor. This could be used to control heating or cooling devices.

The application ClewareControl could be also used to turn the USB-Switch3,5" into a time clock. Up to 256 different time actions may be defined for each connected USB-Switch. This includes actions based on the day of the week or day in month. In addition repeat intervals form several hours down to 3 seconds may be defined.

For easy access a very simple graphical program also comes with the device. The program USBswitch controls the switch just by clicking on icons. And for integration in batch programs, a command line tool USBswitchCMD is available.

The USB-Switch 3,5" may also be controlled via the network when operated with ClewareControl. The connection is established with the TCP/IP protocol. On the remote control PC the USB-Switch 3,5" appears like a local device and could be handled the same way. Several devices even on different PCs could be controlled simultaniously.

An application program interface (API) to drive the USB-Switch 3,5" from customer programs is part of the delivery. The API bundles some very simple functions for opening and reading the device. The complex USB device handling is hided.

Linux support is also available. An application program interface (API) and a simple example for turning an USB-Switch 3,5" is supplied.

Every Cleware device identifies with an unique serial number. This make it easy to identify the devices even when the USB plug position changes or new USB devices are connected. The serial number is accessible through the API and could therefore be used as a simple dongle.

Please note:
PC programs may fail or may be interfeared through other programs. Don't connect devices to the USB-Switch 3,5" that may cause harm if the switch turns on unexpected!

The usage of the USB-Switch 3,5" is strictly prohibited when the failure of the sensor will harm people.
