Typical Application

SuperSwitch application


SuperSwitch is a powerful and flexible but affordable microprocessor controlled switch. The unit interconnects up to nine computers and peripherals using common serial and parallel interfaces. SuperSwitch allows several computers or terminals to have shared access to peripheral devices, such as a printer, a plotter, a modem, or host computer. Peripheral device selection is done either automatically by sending data to the default destination or by sending a code to select a new destination. Any port may communicate to any other port. Pairs of ports may communicate simultaneously.

Several features are included to make setup and use simple and easy. Configuration is done with a menu, and there is a status command, which shows all jobs by origin, destination, status, priority, timeout, and buffer used. Each serial port can be programmed for individual baud rate, word size, parity, stop bits, and flow control. Each of the parallel ports can be configured to act as either an input or output.
