descripción

The Sigma 2 ISA bus 2 port RS-422/RS-485 adapter provides two asynchronous serial communication ports, which enables one computer to communicate with other computers via communication lines, or to link the computer and serial peripheral devices such as terminals, modems, serial printers, plotters, ... etc.

The Sigma 2 ISA bus 2 port RS-422/RS-485 adapter may be configured with up to two individually addressable RS-422/485 ports and individually interruptible for any PC/AT, PC/386, PC/486, Pentium or compatible system. It can be addressed anywhere within the full range of PC I/O ports and each port address can be set individually as your requirement. The interrupt selectable feature provides individual interrupt selection for each port, so that you can arrange the 2 ports in any combination of interrupt you need.
