Installing the QVision Controller
Introduction This chapter describes how to install and connect the QVision
1024/E controller.
About the
QVision 1024/E
Controller
The QVision 1024/E controller is used in an EISA-based personal
computer or system. It allows you to connect a super video
graphics array (SVGA) monitor to the system. You can install
multiple QVision controllers in a system unit. The QVision
controller contains a switch that allows you to select the QVision
controller to be the primary video controller or the secondary
video controller.
In This Chapter This chapter contains the following sections:
• Installing the QVision Controller
• Connecting the Monitor
Installing the QVision Controller 1–1

Installing the QVision Controller
Installing the QVision Controller
Before You
Begin The QVision 1024/E controller contains a switch that you must
set to either the primary or secondary switch setting, depending
on the number of QVision controllers you are installing. This
switch is located on the switch panel SW1 on the QVision
controller. Figure 1–1 shows the location of this switch.
Setting the
Switch If you are installing one QVision 1024/E controller, set switch 1
on the board to the primary (PRIM) setting. If you are installing
more than one QVision 1024/E controller, set switch 1 to the
primary setting on one QVision controller and to the secondary
(SECOND) setting on all other QVision controllers.
Installation
Procedure For information on opening the system unit and installing an
option board, see the DECpc AXP 150 and DEC 2000 Model 300
AXP Customer Technical Information manual.

Running the
ECU To configure the QVision controller within the system or to
change the configuration settings, you must run the ECU. See
the DECpc AXP 150 and DEC 2000 Model 300 AXP Customer
Technical Information manual for information on running the
ECU.
Changing the
Configuration You can use the ECU to change the configuration of the QVision
controller. Table 2–1 shows the functions and the corresponding
choice of settings for the QVision 1024/E controller.

Troubleshooting
Summary This section describes some of the problems that can occur with
the QVision 1024/E controller. It suggests possible causes for the
problems and actions that you can take to correct them.
Identifying
and Solving
Problems
Table 3–1 describes how to identify and solve problems by
interpreting correctly the symptoms that are occurring.
Table 3–1 Troubleshooting Table
Symptom Possible Cause Recommended Action
The QVision controller
device name does not
appear in the power-up
self-test display, or the
system is on but there
is no display.
The QVision controller
is not seated firmly. Remove the QVision controller and reinsert it firmly in the option slot.
The QVision controller
is not correctly
configured or the
configuration conflicts
with another installed
option board.
Use the ECU to check the
configuration and if necessary,
reconfigure the QVision controller
to resolve the conflict.

Troubleshooting 3–1

Troubleshooting
Table 3–1 (Cont.) Troubleshooting Table
Symptom Possible Cause Recommended Action
The monitor, power
cable, or signal cable is
faulty.
If the monitor has a power light
emitting diode (LED), check that it
is on. If it is off, the power cable is
probably faulty. Replace the power
cable.
Swap the cables and then the
monitor to check if they are faulty.
Connect the cables and the monitor
to another system. If the monitor
and cables work on another
system, the QVision controller
or the system unit is faulty. See
the DECpc AXP 150 and DEC
2000 Model 300 AXP Customer
Technical Information manual for
more information.
The monitor or the
system is not switched
on.
Check that the monitor and the
system are both switched on.
The brightness and
contrast controls on
the monitor are set
incorrectly.
Set the brightness and contrast
controls to the correct settings.
See the monitor documentation for
more information.
The system power-up
test displays a VGA
error.
The QVision controller
is faulty. See the DECpc AXP 150 and DEC 2000 Model 300 AXP Customer
Technical Information manual
for information on testing option
boards.
The system board is
faulty. See the DECpc AXP 150 and DEC 2000 Model 300 AXP Customer
Technical Information for more
information. If the problem
persists, contact your system
administrator.
