The Digital Alpha is an eight-line, asynchronous, direct memory access multiplexer that provides local or remote interconnection between Digital Alpha systems and Digital Alpha RS-232-C/Digital Alpha V.28 terminals or other systems. The DHV11 can operate at program or jumper-selectable speeds of up to 38,400 bits per second in full- duplex, with full modem control on each line. Actual device speed is dependent on current Digital Alpha operating systems and system configuration. Split-speed trans- mit and receive rates are supported on each line, making more efficient use of communications facilities by reducing the software demand for the receive line. The DHV11 is compatible with Digital's family of modems and with Bell 100 and 200 series modems and their equivalents. Digital Alpha-M Includes base module only with modern control. For system installation, select one of the following cabinet kits: CK-Digital Alpha-AA For use with Digital Alpha II BAl23 enclosure. Cable length is 21 inches.
