system principles of determinism (predictable behavior), responsiveness,
user control, and reliability for “mission-critical” applications.
Refer to HP-RT System Administration Tasks for detailed installation and
operation procedures for HP-RT.
The HP-RT development environment consists of the following:
•An HP-UX host system (for example, a Model 748i), running the sup-
ported HP-UX operating system, with CDE, X Window System, or HP
VUE installed.
•DDS-format tape drive or CD ROM for loading HP-RT on the host
system.

•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 man commandon a command line, 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 -kkeyword, 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 enteringrtmannameon 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 about.
On your HP-UX system, there are also a variety of files 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
come 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 directory, named by its release number; for example, 10.20RelNotes 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.

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 744. 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
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 lying 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.
•Touching sheet metal with your fingers before touching the printed
circuit assembly.

This section provides step-by-step instructions for installing RAM cards in
the Model 744. The Model 744 memory kit contains a memory card, a set of
standoffs, a set of screws, and a wrist strap.
Preliminary Requirements
Perform the following steps before you install a RAM card into the
Model 744:
1 If the Model 744 is already installed in your system chassis, you must re-
move it. See Chapter 3 of this manual for instructions on removing and
replacing the Model 744.
2 Place the Model 744 on a static-free mat on a clean, level surface.
RAM Card Installation
For a Model 744 in a single slot configuration (no expansion adapter
installed), only one RAM can be installed. In a two-slot configuration, up to
four RAM cards may be stacked. Use these steps and Figure 2-1 to install
the RAM cards:
NOTE:When mixing memory card capacities that include 128MB cards, the 128MB
card(s) must be installed into the lowest memory slots before adding cards of
other capacities.
1 Begin with the Model 744 placed so that you face the front bezel.
2 If the Model 744 has RAM card(s) already installed, remove the screws
that secure the topmost RAM card, and then install the new standoffs that
came with your RAM card onto the topmost card (see Figure 2-1).
3 Hold the RAM card you are installing so that the conferred corner is the
upper-left corner (see Figure 2-1).
4 While placing the new RAM card over the CPU or topmost installed card,
align the holes in the RAM card with the spacers/standoffs underneath it.

Then...
CAUTION:In the Model 748 card cage, slots 1 and 2 are powered by the bottom power
supply . Slots 3 through 8 are powered by the top power supply. A Model 744
Board Computer with its expansion kit attached, installed in slots 2 and 3, will
cause the power supplies to shut down.
To determine the board computer’s power needs, follow these instructions:
1 Determine the board computer’s current requirements from the Computer
Current Requirements Worksheet (Table 3-4).
3-3
Typical Installation in a VME Card Cage
Configuring the VME Card Cage
2 To determine the maximum current usage of the Model 744 memory
cards, either use Figure 3-1 and Table 3-2 (for Model 744/132L) or Table
3-3 (for Model 744/165L). You must work with the worst case power
draw to correctly determine power usage. Determine worst case power
draw by examining active memory bank configurations, using the following steps:
a Examine your memory card configuration, noting which size card is in
each memory slot.
b The worst case active memory bank configuration depends on the slot
position of the memory cards, and the size of the cards. The 32MB
memory card has two banks per card, and the 16, 64, and 128MB cards
each have only one memory bank per card.
•When 32MB cards are used as a pair in memory slots 2 and 3 they
can use three memory banks concurrently.
•When used as a pair in slots 0, 1, or 2, the 32MB cards can have
two active memory banks.
•The 16, 64, and 128MB cards each have only one memory bank
that is active at any one time.
3-4
The worst case power draw would be if your system had 2 32MB
cards in slots 2 and 3 (these banks would be considered active, all
other memory cards/banks would be considered inactive). If you do
not have that configuration, the next worst case would be a 64MB
card in any slot (all other memory cards in the system would be inactive), followed by 2 32MB cards in slots 0, 1, or 2 (all other memory
cards in the system would be inactive), followed by a 16MB card in
any slot (all other memory cards in the system would be inactive).
cInactive memory banks are those banks on cards in your configuration
in addition to the worst case active memory banks, and must also be
added to the calculation.

If your monitor has an attached power cord, connect the plug to a power
source. If your monitor has a separate cord, connect the cord to the monitor,
then connect the plug to a power source.
WARNING:Do not connect your monitor to a power extension strip. Doing so can
cause a shock hazard.
NOTE:Do not turn on your monitor at this time.
Connecting a Terminal
This section provides step-by-step instructions for connecting a terminal to
your Model 744 Board Computer. Refer to Figure 4-3.

nector to one of the RS-232 connectors as follows:
•The recommended port for connecting a terminal is the (A) port.
•Using the (B) port for terminal connection is not recommended.
NOTE:Use of the (B) port requires that VME Services software be installed in the
kernel under HP-UX. The (B) port is not supported during “cold installs” of
HP-UX because VME Services is not installed in the “install kernel”.

Audio Connection
Model 744 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.
1
/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.

LAN circuits use the Ethernet/IEEE 802.3 standard interface. Only the
Attachment Unit Interface (AUI) version is used; no BNC connector is provided for ThinLAN. Figure 4-7 shows the A UI LAN connector. Also refer to
Figure 4-1.
The AUI connector enables connections to an external MAU.
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.
