FCC NOTICE: The equipment. described in this manual generates,
uses, and may emit radio frequency energy. The equipment has been
type tested and found to comply with the limiits for a Class A computing
device pursuant to Subpart J of Part 15 of FCC Rules, which are
designed to provide re:sonabie protection against such radic frequency

interference when operated in a commercial environment. Operation of

Production Note
This book was produced with the VAX DOCUMENT electronic
publishing system, a software tool developed and sold by Digital.
In this system, writers use an ASCII text editor to create source
files containing text and English-like code; this code labels
the structural elements of the document, such as chapters,
paragraphs, and tables. The VAX DOCUMENT software, which
runs on the VMS operating system, interprets the code to format
the text, generate a table of contents and index, and paginate the
entire document. Writers can print the document on the terminal
or line printer, or they can use Digital-supported devices, such
as the LNO3 laser printer and POSTSCRIPT printers (PrintServer
40 or LNO3R ScriptPrinter), to produce a typeset-quality copy
containing integrated graphics.

Product Description

The DWFQA (Q-bus adapter) module makes it possible to use

Q-bus communications and tape data storage options with the
VAXstation 3520/3540. The Q-bus adapter achieves this by
previding a communications link between the M-bus and
Q-bus modules. The DWFQA module supports four Q-bus option
modules with the workstation, though no more than three can be
installed at any one time. The DWFQA module occupies slot 9 of

the system backplane. The various Q-bus option modules occupy
slots 10 through 12.

Q-bus Option Modules
The following Q-bus options work with the DWFQA module:

The DSV11 controller is a quad-height module providing two
synchronous line interfaces allowing high-speed connection to
SNA networks, X.25 networks, and DECnet networks. The
DSV11 supports EIA-232D/V.24 (RS232), RS-423A,

RS-422A, and V.35 standard on both lines. The two lines are

independent and can be used at different speeds and with

different protocols simultaneously. Refer to the DSV11 User
Guide for more information.

The CXY08 asynchronous multiplexer performs data
concentration, real-time processing, and interactive terminal

handling. The CXYO08 module is quad-height, with a BA213-

style handle. The CXYO08 option also includes two cable
assemblies. The module provides eight full-duplex serial
data channels. Each cable assembly has a four-channel
distributor. All eight chanrels provide enough modem control
to allow autoanswer dialup operation over the public-switched
telephone network. Refer to the CXY08 Technical Manual for

‘

more information.

The TK70 is a 13-centimeter (5.25-inch) magnetic streaming
tape drive subsystem that provides up to 296 megabytes

of backup data storage on a tape cartridge. The TQK70
controller is a tape mass storage control protocol (TMSCP)
device that provides the interface between the TK70-AA tape
drive and the Q-bus. Refer to the TK70 Tape Drive Subsystem
Owner’s Manual for more information.
8

The TS05 is a 26.25-centimeter (10.5-inch) 1600-bit,
9-track, industry standard magnetic streaming tape drive that
provides 40.5 megabytes of backup data storage. The TSV05
controlier is a modular, microprocessor-based quad-height
module. It is capable of block-mode direct memory access

(DMA). The TSVO05 is a tape mass control protocol (TMSCP)
device that provides the interface between the TS05 tape

drive and the Q-bus. Refer to the TSV05 User Guide for more
information.

VMS and ULTRIX Support for Q-bus Options
While all of the Q-bus option modules listed above are supported

on VMS (Virtual Memory System), not all of the options are
supported on ULTRIX systems. The following table lists which
options are supported on VMS and which are sapported on
ULTRIX.
Note VMS 5.2 or ULTRIX UWS 2.1 is required for DWFQA support.

Digitel does not support third-party options for the Q-bus adapter.
However, the DWFQA module should work with such options if

third-party manufacturers adhere to the conditions listed below:

The DWFQA module does not fully support block-mode DMA
nor extended block-mode (hog-mode) DMA. Because of the
M-bus architecture, the maximum achievable DMA rates

range from 480 to 650 kilobytes per second.
8

The DWFQA module has the highest M-bus priority.

Third-party options must adhere to Q-bus timing specifications

of 8.2 microseconds.
e

Diagnostics for supported options are stored in four ROMs for

a total of 256 kilobytes.
e

Digital does not support the BA213 expander box on DWFQA.

The System Configuration Tests
After your workstation has been instalied and turned on, it is
important to run the configuration tests to identify your system

modules and their locations.
There are two commands for identifying your systern modules:
Typing TEST 50 at the console prompt (CPUOC >>>) displays

each M-bus module in your system. Typing TEST 50 0 at the
console prompt (CPUOC >>>) displays each Q-bus module in your
system.

Nole When you run the configuration test, check to be sure that all the

modules ordered for your workstation are listed in the display that
appears On your screen.

When you type TEST 50 at the console prompt (CPUOC >>>) and
press the RETURN key, a display similar to that shown below
appears at the bottom of your screen.
