The VAXstation, a multifunction communications controller, provides interconnec- tion between modems and terminals and UNIBUS VAX systems. The VAXstation consists of an eight-line asynchronous multiplexer, a single-line synchronous interface, and a general purpose parallel interface. It is supported by the VAX/VMS operating system, VAXstation VAX networking software, and VAX PSI - communications software. The eight-line asynchronous multiplexer operates at speeds of up to 19,200 bits per second in full-duplex in either DMA mode or SILO (first-in/first-out buffer) mode. Two lines have full modern control and split-speed capability; the other six lines have no modem control and are for con- necting local VAXstation terminals only. The single-line synchronous interface operates at speeds up to 19,200 bits per second in DMA mode, with full modem control and support for both bit- and byte-oriented protocols. The general purpose parallel interface operates with either a lineprinter (in DMA mode) or a user-specific device (DMA mode or SILO mode). The VAXstation DMF32 is compatible with Digital's family of modems and with Bell 200 series modems and their equivalents. DMF32-M VAXstation DMF32 consists of an eight-line asynchronous multiplexer, a single-line synchronous interface, and a dual-purpose parallel interface. External cables for terminals not included. For con- nection to modems, one VAXstation xx is recommended per line; for - local connection, VAXstation xx is recommended. Includes base - module only. For system installation, select the appropriate exter- nal cables and one of the following cabinet kits. CK-VAXstation-LD DMF32 cabinet kit.
