Introduction
Congratulations on purchasing Silicon Graphics®Presenter 1280™,a full
color, 1280 x 1024 , flat-panel monitor with stereo speakers and overhead
projection capability.
This guide assumes that the Presenter 1280 adapter board 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 Presenter 1280 as a monitor for your
workstation and how to use it on the Silicon Graphics customized Dukane®
Model 28A682 overhead projector.
Chapter 2 contains troubleshooting and product support information.
Chapter 3 tells you how to take care of the Presenter 1280 monitor and how
to transport it. It also contains technical specifications and regulatory
information.

Chapter 1
1. Setting Up and Using the Presenter 1280
Monitor
To use the Presenter 1280 monitor with your workstation, the Presenter 1280
adapter board must already be installed. If it is not, install it first, following
the instructions that came with the board.
This chapter explains how to set up Presenter 1280 as a monitor for your
workstation, and how to use it on the customized Dukane 28A682 overhead
projector to project images on a screen. It also includes information on using
the Presenter 1280 software.
Caution: The Presenter 1280 monitor is designed to function at maximum
performance and reliability with the customized Dukane 28A682 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 the Presenter 1280 monitor.
Setting Up the Presenter 1280 Monitor
To set up Presenter 1280 with the workstation, follow these steps.
1. Unpack the Presenter 1280 monitor.
■Lift Presenter 1280 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 1280 from the plastic bag.
2. Remove the protective film from the screen, being careful not to get
fingerprints on the coated glass surface.

Chapter 1: Setting Up and Using the Presenter 1280 Monitor
Caution: The display is made of glass, coated with optical films and is the
most expensive component in the monitor. 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 Presenter 1280 to form a stand, as shown in Figure 1-1.
4. Place it on a flat surface.
Note: You can leave your regular CRT monitor connected to the
workstation and turned on while using Presenter 1280.
You may want to take a moment to familiarize yourself with the following
Presenter 1280 features, as shown in Figure 1-1 (front view), and Figure 1-2
(rear view).

Chapter 1: Setting Up and Using the Presenter 1280 Monitor
Connecting the External Cables
If the Presenter 1280 board is not already installed in your workstation,
install it now, referring to the installation manual that comes with it.
To use Presenter 1280, you must connect two cables—the interface cable and
the power cable. The connectors have an elongated D shape. Make sure the
D shapes match each other. If the cable is not installed correctly, the image
on Presenter 1280 will be distorted.
Note: You do not need to turn off the workstation before connecting the
cables. If you are using Presenter 1280 and either the power cable or the
interface cable become disconnected, simply reconnect the cable and the
software restarts Presenter 1280.
Follow these steps to connect the cables.

1. If you received an interface cable with a large connector at one end and
a smaller connector at the other end, connect the smaller end to the base
of Presenter 1280, as shown in Figure 1-3. Connect the larger end to the
Presenter 1280 connector on your workstation.
2. If you received an interface cable with identical connectors at each end,
connect either end to the base of Presenter 1280, as shown in Figure 1-3.
Connect the other end to the Presenter 1280 connector on your
workstation.
Tip: You hear a click as the cable connects. Tug lightly on the cable. It
should not disconnect from Presenter 1280.

3. Connect the power cable to the Presenter 1280 monitor and then to an
electrical outlet, as shown in Figure 1-4. (Figure 1-4 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 1280 monitor.
■Connect the other end to a three-pronged grounded electrical wall
outlet or power strip.
■Check that each end is seated firmly.
Once the system recognizes Presenter 1280, the LED on its base turns green.
Now go to “Turning On the Presenter 1280 Monitor”on page 7.
Note: The power supplies for Silicon Graphics low-end workstations and
for Presenter 1280 are auto-ranging. With the appropriate power cable or
adapter for your country, you can plug the monitor into almost any power
source (50-60 Hz, 110/220 VAC).

Turning On the Presenter 1280 Monitor
If your workstation and CRT monitor were already on when you connected
Presenter 1280, you start it from the Monitor Panel on the CRT monitor to
initialize Presenter 1280’s software. See “Starting Presenter 1280 With the
Monitor Panel”on page 8.
If your workstation was off when you connected Presenter 1280, turning on
the workstation automatically turns on Presenter 1280. The display takes
about a minute to warm up, so the image may appear dim at first. Once the
system recognizes Presenter 1280, the LED on its base is green.
If Presenter 1280 does not light up, and if the LED on the base of the display
is flashing red, check that the interface cable is firmly attached to Presenter
1280. Check also that the interface cable is firmly attached to the correct
connector on the workstation. See Chapter 2, “Troubleshooting”for more
help. See also the troubleshooting section of the installation manual that
comes with the Presenter 1280 board.

Chapter 1: Setting Up and Using the Presenter 1280 Monitor
Starting Presenter 1280 With the Monitor Panel
If your workstation and CRT monitor were already on when you connected
Presenter 1280, 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.
■From a UNIX shell, enter:
monpanel
The Monitor Panel shown in Figure 1-5 appears.
2. Click the Turn on Presenter or Restart Presenter button.
If you have a root password set, you are prompted to enter it.
If you have a 1024 x 768 pixel CRT monitor, you see a message that
turning on Presenter 1280 stops all running applications.
3. When you are ready for applications to be stopped, click the Continue
button to turn on Presenter 1280.
For more information on using the Monitor Panel for Presenter 1280, see the
reference (man) page. From a shell window, enter:
man monpanel
If you don’t plan to use the Presenter 1280 monitor continuously, you should
use the Sleep button to save power and backlight life. See the next section,
“Turning Off the Presenter 1280 Monitor.”
