NTI SERIMUX SERIES CONSOLE SWITCH INTRODUCTION The NTI SERIMUX Console Switch is a serial port router that allows links (or connections) between multiple pairs of RS-232 asynchronous serial ports. The main purpose of the switch is to enable users to manage several serial devices from local or remote locations (using external modems). Devices include routers, DSU's, servers, switches or any other equipment allowing serial operation using RS232 interface.
