stimulation, and instrument setup data to or from the DAS. Various types of
parallel and serial printers are supported to generate non-color (monochrome)
reproductions of display screens and acquisition and pattern-generation data.
Using the optional 92XTerm software (also known as DASNT systems), you can
operate the DAS from a window on a workstation. The interactive menus appear
in the workstation window and are controlled with the mouse and keyboard.
Communication between the DAS and the workstation is over a local area
network (LAN).
As a peripheral device remotely controlled by a host computer, the DAS supports
a Programmatic Command Language (PCL) that is an alternative to the keyboard
and menu interface. PCL commands let you start and stop acquisitions, manage
files, and report status and error information. Data can be processed either by the
DAS or the host computer; when the host computer processes data, the DAS is
the source of raw or partially processed data.
Mainframes and Terminals
The mainframes provide computing power, input and output features, and mass
storage for your modules. The mainframe provides enhanced computing power
due to its larger memory and faster CPU. The mainframes exist in the following
versions:
H DAS 9221 with 16 Mbyte RAM on the Controller board, 100 Mbyte (or
H DAS 9220 with 8 Mbyte RAM on the Memory board, 40 Mbyte hard disk
H DAS 9219 with 2 Mbyte RAM on the Memory board, 20 Mbyte hard disk
The DAS 92E9 is an Expansion mainframe with extra slots for additional modules.

Introduction to DAS Hardware
Terminals
The standard display device is a Tektronix color terminal with a detachable
keyboard. Earlier versions of the DAS used a 9200T or a 9201T monitor; newer
versions use an X terminal with a detachable keyboard and mouse. Interactive
menus, which are manipulated from the keyboard or mouse, allow you to define the
contents of the system, enter parameters and data, and control the outputs of the
instrument. These menus use color-coded command fields to show the available
selections.
You can power on and power off your mainframe and terminal from a 9200T or
9201T using the terminal power button. This feature is built into DAS 9221
mainframes; for DAS 9219/9220 mainframes, you must install an optional
one-button power-switch adapter.
The 9201T is a direct replacement for the 9200T, so references in this manual to
the 9201T also apply to the 9200T. However, references to the 4205 Service
Manual apply only to the 9201T; if you use a 9200T, refer instead to the 4105
Service Manual.
The X terminal requires a 92LANSE LAN (local area network) module installed
in the mainframe. You can use the X terminal only with the DAS/SE, DASXP, or
DASNT mainframes. For service information, refer to the TekXpress X Terminal
Service Manual.

Mechanical Chassis. The chassis provides the mechanical connection and cooling
for all mainframe components and options. DAS modules reside in the card cage;
probes connect to the modules through openings in the rear of the chassis.
NOTE. To install, remove, or reposition any DAS module, you must remove the
mainframe top cover and card-cage door.
To disassemble major chassis components, refer to Disassembly/Reassembly
Procedures beginning on page 3–3.
Controller Board. The Controller board resides in slot 0 of the Master mainframe;
Expansion mainframes use an Expansion Slave board instead of a Controller
board. The Controller board provides the following resources:
H DAS 9221 mainframes use a 68EC030 microprocessor with address
decoding for an asynchronous bus structure (32-bit address, 32-bit data).
DAS 9219/9220 mainframes use a 68010 microprocessor (24-bit address,
16-bit data).

Introduction to DAS Hardware
H Nonvolatile RAM for storing interrupt routine addresses, previous shutdown
conditions, and pointers to other processes
H 64 Kbytes of boot ROM in DAS 9221 (32 Kbytes in DAS 9219/9220) for
power-up sequences and diagnostics
H 16 Mbytes of dynamic RAM (DAS 9221 only) with refresh circuitry
H A communication interface between circuit boards, the hard disk drive, and
the floppy disk drive
H Asynchronous time bases and other circuitry supporting the expansion of up
to four time-aligned mainframes
H A clock/calendar with battery backup
H Power-supply control for mainframe shutdown
Memory Board (DAS 9219 and DAS 9220). There are two different Memory boards:
the 2 Mbyte dynamic RAM board is standard with the DAS 9219, and the
8 Mbyte dynamic RAM board is standard with the DAS 9220. The 8 Mbyte
board is also available as a performance upgrade for the DAS 9219. Only one
Memory board can be installed in the Master mainframe, and it must reside in
slot 1; Expansion mainframes do not use a Memory board. (The DAS 9221 has
Memory-board functions resident on the Controller board.) The Memory board
provides the following resources:
H 2 Mbytes of dynamic RAM (standard with the DAS 9219) with refresh
circuitry for supporting system software, post-processing of acquired data,
and other calculations.
H 8 Mbytes of dynamic RAM (standard with the DAS 9220) with refresh
circuitry. The lower part of RAM supports system software and post-proces-
sing of acquired data. The upper part of RAM temporarily stores configura-
tion and data files to improve the system response time.
H Circuitry supporting the Memory Management Unit (MMU), for multiple
process control.
H An interface to the Controller board, allowing access to the system RAM and
to the terminal, host, and auxiliary communication ports.
Backplane Board. This board provides the mechanical and electrical connections
between the Controller board, the Memory board (DAS 9219 and DAS 9220),
and the eight slots used for the acquisition and pattern generation modules.
Signals are carried on bus structures, some of which extend outside the Master
mainframe to Expansion mainframes.

Introduction to DAS Hardware
Hard and Floppy Disk Drives. The operating system software is installed on the
hard disk, along with other files (such as user-generated setups and reference
memories).
The DAS 9221 mainframes have been available with 100 Mbyte, 127 Mbyte,
170 Mbyte, and 270 Mbyte SCSI hard disk drives. The DAS 9220 mainframes
used 40 Mbyte and 80 Mbyte hard disk drives (ST506 interface), while the
DAS 9219 mainframes had 10 Mbyte and 20 Mbyte hard disk drives. To
determine the size of hard disk in your mainframe, refer to the Diagnostic menu.
An optional 80 Mbyte hard disk drive is available for DAS 9219/9220 mainframes. If data security or portability is a concern, you can order your mainframe
with a removable hard disk drive, so that setup and data files can be secured
overnight or easily transported to another DAS. An 80 Mbyte removable drive is
available for the DAS 9219/9220; a 127 Mbyte, 170 Mbyte, or 270 Mbyte
removable drive is available for the DAS 9221. (Other versions of the removable
hard disk drive were available for earlier versions of the mainframe.)
WARNING. The removable drive for the DAS 9221 (SCSI drive) is not interchangeable with the removable drives for the DAS 9219/9220 (ST506 interface
drives). If you install the wrong type of drive into your mainframe, you can
damage the drive.
Do not disconnect or remove the removable hard disk drive while the mainframe
is powered. Doing so will damage the hard disk or corrupt the file system.
The floppy disk drives are used for loading application software from floppy disk,
copying files for use on other mainframes, and making and restoring backup files.
Backup procedures with on-screen instructions are available. A light on the front of
the floppy disk drive indicates when a floppy disk is being accessed.
A 3.5 inch, 1.4 Mbyte floppy disk drive is standard in DAS 9221 mainframes
with System Software Release 3, Version 1.40 and higher. The floppy disk drive
is also available as an upgrade kit for older systems.
A 5.25 inch, 1.2 Mbyte floppy disk drive was available in earlier versions of the
DAS 9220 and DAS 9221 mainframes. This disk drive is available as an option
for the DAS 9219 mainframe. This drive reads floppy disks written in
360 Kbyte/400 Kbyte format; however, it cannot write to disks of this type. For
write operations, use only 96 TPI (tracks per inch), double-sided, high-density
floppy disks with this drive.
A 5.25 inch, 400 Kbyte floppy disk drive was standard in the DAS 9219
mainframe. This drive can read or write to floppy disks in 360 Kbyte/400 Kbyte
format only. Use only 48 TPI, double-sided, double-density floppy disks with
this drive; do not use 96 TPI high-density disks.
