There is a number of the equipment controlled through a serial port from a PC or a terminal. Also there is a lot of the technologies in the market allowing to operate remotely the consecutive devices through the network TCP/IP. These solutions contain, both software and the hardware. Our company as well has the like solution: it is a product for the remote control of consecutive devices ENSD. Nowadays there are more and more devices with interface USB as alternative to the parallel or consecutive connection, but there are still no decisions on the remote control of USB devices. One can think that there is no need in such solutions or they are not applicable in real life. In order to refuel this opinion we present here some examples of application of this technology. LetOs suppose you have purchased the software protected by USB HASP KEY, but you want this product to be used on several computers, but in different time. If the computers are located close - it is not a problem to pull out the USB HASP KEY from one computer and to insert into another. There is a problem when the computers are located in different premises, or it is worse than that, in different cities (two sub-units of the same firm). Then it is necessary for you to purchase the additional license for the product and it may cost you thousand $. In this case our product can solve your problem, thus you do not break requirements of the license agreement since simultaneously the product can work only on one computer. The same concerns the purchase of various USB equipment in several copies when it is possible to use one copy through the TCP/IP network. Our product allows to use any USB equipment located far away through the TCP/IP network.
