<p>Device for manual input of information into a computing system, providing for transmission of the input information through a two-wire high-distance line while maintaining a high degree of quick response, noise stability and reliability. The device comprises a wire commutation matrix (1) to the horizontal wires (2) of whichis connected a first multichannel delay circuit (4) and to the vertical wires (3) of which is connected a second multichannel delay circuit (5). When a tester (13) connected to a voltage source (14) is connected to a given node of the commutation matrix (1) of wires then on the outputs of the delay circuits (4, 5) are generated signals whose delay time characterizes the coordinates of the corresponding node of the commutation matrix (1) of wires and, thus, expresses the input information.</p> |
