Introduction
Congratulations on purchasing the Presenter, Silicon Graphics’1024 x 768
full-color, flat-panel monitor with stereo speakers and overhead projection
capability.
This guide assumes that the hardware adapter board for the Presenter is
installed in your workstation. If it is not, install it first, following the
instructions in the manual that comes with the adapter board.
Chapter 1 explains how to set up the Presenter as a monitor for your
workstation and how to use it on the Silicon Graphics®customized
Dukane®overhead projector. You can use the Presenter with either the
Dukane 28A681 or 28A682 projectors.
Chapter 2 contains troubleshooting and product support information. It also
explains how to clean the Presenter, and how to pack it for shipping.
Chapter 3 provides technical specifications and regulatory information.
Appendix A provides technical information on liquid crystal display
technology.

Chapter 1
1. Setting Up and Using the Presenter Monitor
This chapter explains how to set up Presenter as a monitor for your
workstation, and how to use it on the customized Dukane overhead
projector to project images on a screen.
Before using Presenter, make sure the Presenter adapter board has been
installed in your workstation.
Caution: Your Presenter monitor is designed to function at maximum
performance and reliability with the Dukane Overhead Projector. If you use
another projector, cooling of the display, stable mounting, and brightness of
the projected image will all be compromised. A bright overhead projector
without proper cooling of the display may cause permanent damage to Presenter.
Setting Up the Presenter Monitor
To set up Presenter with the workstation, follow these steps.
1. Unpack the Presenter monitor.
Note: Don’t be concerned that the name on the Presenter monitor is
“Indy Presenter.”With the Presenter adapter board installed, the Indy
Presenter works on other workstations.
■Lift the Presenter monitor and the external cables from the box. It’s
a good idea to save the original shipping materials in the event that
you need to return it for service.
■Remove Presenter from the plastic bag.

Chapter 1: Setting Up and Using the Presenter Monitor
2. Remove the protective film from the screen, being careful not to get
fingerprints on the coated-glass surface.
The display is made of glass, coated with optical films and is the most
expensive component in the Presenter. A sharp instrument such as a
pen can scratch the surface. Striking the surface with a hard object can
break the glass.
3. Tilt the base of the Presenter to form a stand, as shown in Figure 1-1,
and place it on a flat surface.
Note: You can leave your CRT monitor connected to the workstation while
using the Presenter.

Connecting the Cables
If the Presenter board is not already installed in your workstation, install it
now, referring to the installation manual that comes with it.
To use the Presenter monitor, you must connect two cables:
•the interface cable (the one with identical flat connectors at each end)
•the power cable
Note: You do not need to turn off the workstation before connecting the
cables.

Chapter 1: Setting Up and Using the Presenter Monitor
Follow these steps to connect the cables.
1. Connect the interface cable to the Presenter. It’s important that you
connect the interface cable before the power cable.
The connectors on the cable and on the Presenter have an elongated
“D”shape. Make sure the “D”shapes match each other.
■Connect either end of the interface cable to the connector on base of
the Presenter, as shown in Figure 1-2.
■Connect the other end of the interface cable to the Presenter adapter
I/O port on your workstation. If necessary, refer to the installation
manual that comes with the Presenter board.

2. Connect the power cable to the Presenter and then to an electrical
outlet, as shown in Figure 1-3. (Figure 1-3 shows the power cable for the
U.S.A. The power cable for your country may look different.)
■Connect the socket end to the power connector on the base of the
Presenter.
■Connect the other end to a three-pronged grounded electrical wall
outlet or power strip.
Note: The power supply for the Presenter is auto-ranging. With the
appropriate power cable or adapter for your country, you can plug the
Presenter into almost any power source (50-60 Hz, 110/220 VAC).

You are now ready to use the Presenter monitor.

Chapter 1: Setting Up and Using the Presenter Monitor
Turning on the Presenter
The Presenter has no power switch. If your workstation and CRT monitor
are on when you connect the Presenter, you start the Presenter from the
Monitor Control Panel. See “Starting Presenter With the Monitor Control
Panel”below.
If your workstation is off when you connect Presenter, turning on the
workstation automatically turns on Presenter. The display takes about a
minute to warm up, so the image may appear dim at first.
If there is no image on the Presenter, make sure the external cables are
connected correctly, as described in “Connecting the Cables”on page 3.
Then go to Chapter 2, “Troubleshooting”for help in solving the problem.
Note: If you have a high resolution (1280 x1024 pixels) CRT monitor
connected to the workstation and you connect the Presenter, the CRT
monitor is set to 1024 x 768 pixels. Therefore icons at the extreme edges of
your screen may not be visible. To remedy this, move the icons away from
the edges of the screen before turning on the Presenter. If you disconnect the
Presenter and wish to return your CRT monitor to its default resolution, type
the following from a UNIX shell:
su
/etc/killall Xsgi
If the workstation is on and Presenter is disconnected, see “Restarting the
Presenter Monitor”on page 7.
Starting Presenter With the Monitor Control Panel
If your workstation and CRT monitor were already on when you connected
Presenter, follow these steps to start it:
1. On the CRT monitor, open the Monitor Panel in either of the following
ways:
•From the Find menu in the Toolchest, choose “Control Panels,”and
double-click the monpanel icon.

Turning on the Presenter
7
•From a UNIX shell, enter:
monpanel
2. When the Monitor Control Panel appears, click Turn on Presenter or
Restart Presenter.
If you have a root password set, enter it when prompted, and click the
OK button.
If your CRT monitor is 1024 x 768 pixels, you see a message that turning
on the Presenter stops all running applications. Close any applications
for which you may lose data.
3. When you are ready for applications to be stopped, click Continue to
turn on Presenter.
For more information on using the Monitor Control Panel for the Presenter,
see the reference page (man page). From a shell window, type:
man monpanel
Restarting the Presenter Monitor
If the workstation is on and Presenter is disconnected, you can reconnect it
and restart it from the Monitor Control Panel on the CRT monitor. See the
steps below. Note that restarting the Presenter resets the backlight and bit
mode to their original settings, that is, nearly full backlight and 12-bit mode.
If you have no CRT monitor attached there are two ways you can restart
Presenter:
•Reconnect Presenter and restart the workstation.
•If you are on a network, use the Monitor Control Panel to restart the
Presenter. From another system on the network, log in to your system
remotely, and type monpanel -restart at the shell prompt.
Follow these steps to restart Presenter:
1. Open the Monitor Panel in either of the following ways:
■From the Find menu in the Toolchest, choose “Control Panels”and
double-click the monpanel icon.

Chapter 1: Setting Up and Using the Presenter Monitor
■From a UNIX shell, enter:
monpanel
2. When the Monitor Control Panel appears, click Restart Presenter.
Turning Off the Presenter
The Presenter turns off automatically when you turn off the workstation.
If you have a CRT monitor connected to your workstation, you can
disconnect the Presenter’s interface and power cables instead of powering
off the workstation. To restart the Presenter, connect the interface cable and
then the power cable. Then open the Monitor Control Panel on the CRT
monitor by choosing “Control Panels”from the Find menu in the Toolchest
and double-click the monpanel icon. Then click Restart Presenter.
Note: It’s important when you reconnect the Presenter’s cables that you
connect the interface cable first and then the power cable. Connecting them
in the reverse order results in a distorted image.
If no CRT monitor is connected to the workstation, you can disconnect the
Presenter’s interface and power cables instead of powering off the
workstation. To restart the Presenter, reboot your workstation after
connecting the interface cable and the power cable.
If you are not planning to use the Presenter for a few hours, it’s a good idea
to disconnect it. Leaving the display on for long periods of time shortens the
life of the display’s backlight.
Setting Up the Presenter on the Dukane Customized Projector
Caution: The Presenter is designed to function at maximum performance
and reliability with the Dukane Overhead Projector. If you use it with
another projector, cooling of the display, stable mounting, and brightness of
the projected image will all be compromised. A bright overhead projector
without proper cooling of the display may cause permanent damage to the Presenter.
