File No. 8360-19 Form A22-6844-1 Systems Reference Library IBM 2701 Data Adapter Unit Original Equipment Manufacturers' Information This publication describes the IBM 2701 Data Adapter Unit in- terfaces. The processor interface description provides system attachment information. The transmission adapter interface descriptions provide device attachment information. The elec- trical, mechanical, and cabling specifications of these inter- faces are provided, together with general physical planning requirements. This pUblication is a major revision of form A22-6844-0 and obsoletes it as well as the associated Technical Newsletter, form N22-0190-0. The manual has been completely reorgan- ized and includes a new section on the processor interface. All other sections have been revised to reflect the latest en- gineering data. PREFACE This publication contains information required to attach an IBM 2701 Data Adapter Unit to non-IBM equipment. It contains a general description of machine functions, a reference list of related publi- cations and engineering documents, and interface information not readily available in other publications. Users of this pUblication are cautioned that speci- fications are subject to change without notice. The data in this publication reflects engineering s pecifica- tions as of December 1, 1965. Complete wiring dia- grams at the latest level are included with each machine shipment. Whenever this publication is af- fected by major engineering changes, it will be up- dated by a Technical Newsletter or a revision. Part numbers specified in this pUblication are sub- ject to change by IBM. The user is advised to verify part numbers with the local IBM Branch Office before ordering parts. All descriptions and data in this manual are sub- ject to modification as a result of engineering develop- ment. Unless otherwise stated, the grounding of various external devices to the 2701 is made at the power source common. However, when the power sources differ (thus allowing the frames of different machines to be at different potentials) and when the machines are close enough to one another to present a hazard- 0us condition, other grounding methods must be used. In no case should interface lines designated as grounds be used to establish a common frame grounding.
