Installation Overview
Installation Overview
Chapter 2 provides step-by-step instructions for attaching and installing
accessories in a typical VME chassis, and connecting external devices.
Accessories are products that attach to the computer’s system board and
must be attached before installing the board computer in a VME card cage.
Devices are products used externally to the board computer. Examples are
keyboards, monitors and mass storage devices. Other devices are connected
through cables. Depending on your specific application, you may need one
or more accessory and device products. Installation instructions for most
products used directly with your Model 743 Board Computer are explained
in this manual.
Chapter 3 presents the installation tasks required to install the board computer. It provides information to help you configure and install your VME
board computer.
Installation Notes
Your Model 743 Board Computer uses micro-miniature connectors for several interface ports. Cable connectors for these ports are very small, but may
be positioned so that a slight angle exists between them. This situation has
been tested by HP and full functionality is maintained.
CAUTION: The Model 743 Board Computer’s P2 connector has a local bus on the user-
defined pins. Verify that your VME card cage’s backplane makes no
connections to J2/P2, rows A and C. Refer to IEEE STD 1014-1987, Chapter

Model 743 Board Computer Overview
Online Sources of Information (HP-UX and HP-RT)
Online Sources of Information (HP-UX and HP-RT)
HP-UX is designed so that you can access many sources of information
without leaving your system. Most of these information sources are accessible through the shell command line on a character terminal.
• Man Pages: The HP-UX information found inHP-UX Reference is online
and accessible by clicking on the Toolbox button at the right of your Front
Panel, or by entering on a command line man command, where command
is the name of the HP-UX command or routine you want to get information on. If you’re not sure of the command name you can enter man -k
keyword, where keyword is a likely topic word to search on. This results
in a display listing commands having the keyword in their description.
Similar reference information on HP-RT, found in HP-RT Reference, can
be displayed by enteringrtman name on your HP-UX host system, where
name is the name of the HP-RT command, system call, or function call
you want to get information on.
There are also a variety of files on your HP-UX system which contain version-specific information. These will be useful in administering and configuring cards and devices for your version of HP-UX. Among these files are
the following:
• Release Notes: This is the online version of the Release Notes which
comes with your system. It contains all the latest information, undocumented changes and bug fixes for your release of HP-UX. It also contains
information on the current version of HP VUE. The Release Notes document resides in the /usr/share/doc or/etc/newconfig directory, named by
its release number, for example, 10.20 RelNotes for HP-UX 10.20.
• HP-UX and HP VUE Help. For graphics displays, extensive help information on the operating system and the visual interface is included with
HP VUE.
• Newconfig: The directory /etc/newconfig contains information and new
versions of HP-UX product configuration files, as well as shell scripts
which may have been customized on your system. The contents of this directory will vary depending on which products you have loaded on your
1-15
Model 743 Board Computer Overview
Online Sources of Information (HP-UX and HP-RT)
system. In most cases, old versions of these files, in their regular locations
in the file system, are not overwritten by the update process. See the
README file in /etc/newconfig for information on the contents of this
directory.
In HP-RT, you will find an HP-RT specific README file in
$HPRTroot/etc/newconfig, on the HP-UX host system. This file contains
version-specific information.

Model 743 Board Computer Overview
Audio
Audio
HP-UX includes audio software comprising an audio editor, Audio Application Program Interface (AAPI), and some sample programs. Audio output is
available through the audio port on the front panel of the Model 743i. For
highest quality audio, an external headphone set or speaker is recommended.
Audio is implemented using a CODEC (coder-decoder) combining CDquality stereo audio-digital converters for microphone and line-input levels.
The input sampling rate and format are programmable, as are the input gain
and output attenuation.
1
/8-inch mini-jack is used for the speaker output connection. The remain-
A
ing audio signals are via a 9-pin D-sub connector. Output impedance is nominally 8 ohms, but higher impedance devices can also be driven.
For information on programming for audio, refer to Using the Audio Devel-
oper’s Kit (B2355-90069) and the man page audio.

Safety Precautions
Safety Precautions
CAUTION: It is essential to practice safety precautions when working with any electrical
or electronic products. Following these safety precautions can help protect
both you and the equipment from injury and possible permanent damage.
Whether the ICs are installed on a printed circuit board or laying on a table,
integrated circuit components can be damaged by electro-static discharge.
Static charges can build up in people to a potential of several thousand volts
by simply walking across a room.
Protect integrated circuits by:
Using a static free work place and wearing clothes that do not hold static
charges before handling any of the workstation’s PC boards.
Unplugging the power supply before removing or installing a part.
2-4
Touching sheet metal with your fingers before touching the printed circuit
assembly.
If the assembly is not going to be re-installed, place the assembly in an antistatic bag and set it aside. Following these precautions extends the life of the
computer products you maintain.

Audio Connection
Model 743 Board Computers provide compact disc-quality audio input and
output in stereo with a 16-bit coder-decoder (CODEC) over a frequency
range of 25-20,000 Hz. Output is provided by a small internal speaker and a
stereo headphone mini-plug (8 ohms impedance). Input is provided by a stereo line-in and mono microphone mini-plugs.
The CODEC combines CD quality stereo A/D converters for microphone
and line input levels. D/A con v erters for driving headset and line outputs are
used. The input sampling rate and format are programmable, as are the input
gain control (used for software control of recording levels) and output attenuation.

/8-inch mini-jack is used for the speaker out connection. The other audio
A
signals are on a 9-pin micro D-sub connector. The output is capable of driving 8 ohms; it can also be used for higher impedance devices with little or no
additional distortion. A line-level input can be driven by the headset output.

Preparing for HP-UX Installation
You may have to do some configuration for appropriate data interchange
with a new printer. This section gives you general guidance for these tasks.
You can use SAM (System Administration Manager) procedures to make
your printer installation easier. SAM can determine the status of an y of your
connected devices and performs the necessary software installation of the
printer for you.
If you don’t want to use SAM to install the printer, or if SAM is not on your
system, you can use HP-UX commands directly to accomplish the same
tasks. For information on using manual system administration procedures,
see HP-UX System Administration Tasks.
4-16
Configuring HP-UX for a Printer
You will need to supply certain items of information needed to identify the
printer you are installing. It will help to have this reference information
available during the software installation process. In the following checklist,
fill in the items relevant to your printer:
Printer Interface
• Parallel:_____________________________________________
• Serial (RS-232C) (Port A):______________________________
• Serial (RS-232C) (Port B): ______________________________
• Printer Name (a name the system uses to identify the printer. It can be
any name.):________________________________________
• Printer Model Number (located on a label on the back of the printer):_________________________________________________

SCSI Connection
The built-in SE SCSI port is implemented using an NCR710 macrocell
inside the I/O ASIC chip. This 8-bit single-ended implementation is compatible with the current Series 700 products and supports 5 MB/sec data transfer rates.
The SCSI bus is terminated to 3.3 volts through 127 Ohms on the system
board. If the board computer is used in a VMEbus chassis having internal
mass storage devices, those devices must have their terminators removed. If
an external disk drive is used, an active terminator must be used on the last
drive’s uncabled connector.
