DLV11-J

This document is a comprehensive user's guide for the DLV11-J, an LSI-11 bus-compatible interface module (M8043) that provides four independent asynchronous serial line channels.

Key information provided in this manual includes:

• System Features: Details on the four serial channels, which support configurable baud rates (150 to 38,400 bits/s), various data/stop bit formats, parity settings, and console device designation for channel 3.
• Installation and Configuration: Step-by-step instructions for configuring module jumpers (base device addresses, interrupt vectors, and channel options) and installing the module into an LSI-11 backplane.
• Programming: A breakdown of the 16 device registers (RCSR, RBUF, XCSR, XBUF), interrupt handling, and console device operation.
• Technical Specifications & Description: Detailed electrical and physical specifications, a technical breakdown of the bus interface, I/O control logic, register logic, and UART operation.
• Cabling: Information on various cable configurations, including connections for modems, local terminals, and other SLU modules, as well as the optional DLV11-KA 20 mA current loop support.
• Testing: Procedures for performing checkout and acceptance tests using an optional diagnostic loopback plug (H3270-A).
