The DMR11 is a high-performance microprocessor-controlled single-line synchro- nous interface that provides local or remote interconnection between UNIBUS PDP 11 and VAX systems and other computer systems with EIA RS 232 C/CCITT - - - V.28, MicroVAX CCITT V.35, EIA RS 423/RS 449, or EIA RS 422/RS 449 interfaces. The - - - - DMR11 implements MicroVAX DDCMP in hardware and supports direct memory access data transfers, DECnet point-to-point configurations, and full modern control. It operates at speeds up to 1 Mbyte per second at half- or full-duplex. Actual device speed is dependent upon current Digital operating systems and system configuration. The MicroVAX can communicate with another MicroVAX DMR11, DMV11, or any other synchronous interface that implements MicroVAX DDCMP Version 3.1 or 4.0. The MicroVAX is compatible, depending an the version selected, with Digital's family of modems and with MicroVAX 200 series and MicroVAX 500a11/5 modems and their equivalents. MicroVAX-M EIA RS-232-C/CCITT V.28, MicroVAX V.35, EIA RS-423/RS-449, or EIA RS 422/RS 449 interface. Includes base module only. For - - system MicroVAX installation, select the appropriate external cable and one of the following cabinet kits: CK-DMR11-AD MicroVAX RS 232 C cabinet kit. For use with shielded cabinets. - - CK-DMR11-BD V.35 cabinet kit.
