INTRODUCTION

This technical manual contains operation and maintenance instructions
for the EDL Model 6115, 6116, 6119 and 6120 MasterSync Video
Monitors. These models are high quality, high performance, high
resolution color monitors. They are unique in their ability to automatically
synchronize and display virtually any video format. This feature makes it
very useful as a communications monitor when integrated with a video
switch system as well as Windows applications.

This manual should be carefully reviewed before attempting operation.
A thorough understanding of the control functions is required for proper
set up and operation of the monitors.

To achieve the best results from these models please follow the
procedures in the order given below:

1. Review the Operation and Maintenance Manual.

2. Determine the operating system format and the system signal input
cabling required. Follow the guide in this manual when attaching
system input cabling.

3. If customized calibration is required, follow the calibration
procedures in this manual.

When corresponding with EDL Displays relative to this equipment,
please include the model number and serial number of the monitor in
question.

GENERAL INFORMATION

VERY HIGH RESOLUTION

EDL Displays Color Monitors have the highest resolutions available. The dynamically
focused 0.28mm dot pitch (0.25 for Model 6120)cathode ray tubes provide the
sharpest images available with resolutions up to and including 1600 x 1280 for 6119 &
6120 (1280 x 1024 for Models 6115 and 6116).

VIDEO BANDWIDTH

The video bandwidth of 140MHz supports resolutions up to 1600 x 1280 @ 60 Hz NI.

AUTOMATIC SYNC ADAPTATION

These monitors will automatically sync and display any RGB video format within its
operating frequency range. It will automatically accommodate five (5), four (4) and
three (3) cable signal formats in that order of priority.

EASE OF ADJUSTMENT

All controls that may be necessary to adjust in the field are acces sible either at the
front or rear panel.

RELIABILITY

The monitor is designed with reliability as paramount in importance. Reliability is
accomplished by using high quality parts and assuring that these parts are operating
at less than their intended stress levels. All devices which must dissipate heat are
mounted on the rear panel heat sinks. This allows for convection cooling of the
monitor eliminating the need for potentially unreliable fans.

MODULAR CONSTRUCTION

The monitor is constructed around a card cage configuration. All circuitry is in the
form of plug-in modules which plug into the rear panel of the unit.

6115 - 6120 Operation and Maintenance Manual 2 EDL Displays, Inc. January 1997

CONFIGURATION CONTROL

Any changes to the monitor design are form, fit, and function to previous revisions.
The replaceable modules in the units delivered today are backward compatible into the
first EDL Displays product shipped in January 1990.

MAINTAINABILITY

All circuitry within the monitor is contained in functional replaceable modules such as
deflection output, microprocessor control, video amplifiers (3), and power supplies. A
defective module can be detected by simple tests and the monitor can be repaired by
replacing the module. This may eliminate the need for a field service representative or
shipment of the monitor back to the factory.

An important benefit of these plug-in replaceable modules is the very short Mean­Time-To-Repair (MTTR).

Since the replaceable modules are the same as used in other EDL Displays products,
sparing and personnel training are greatly simplified.

LOOP THRU OPERATION

Loop thru operation is provided by a HI-LO impedance switc h selection. This allows
the use of the monitor with other devices on the output of the raster engine or video
switch.

INSTALLATION

GENERAL

This section describes the installation of the monitor. The monitor is pre-aligned at the
factory to user input requirements. However, there may still be the need for some minor
adjustments to be made. Those procedures will be provided later in the Calibration
Procedures section.

UNPACKING

Before unpacking, the carton should be inspected for shipping damage. The carton
should be carefully opened and the monitor removed. The monitor should then be
carefully inspected for shipping damage. If damage has occurred, the shipping carton
and all packing materials should be saved for possible inspection by the shipping
company. The shipping company and EDL Displays should be notified at this time.

AC POWER CONNECTION

Before connecting the monitor, determine what a.c. power is to be used and make sure
that the monitor is configured properly for that voltage. NOTE: The power setting upon
shipment is 110 volts unless otherwise requested by the customer. The voltage of the
monitor may be changed at the power supply module accessible from the rear of the unit.
The power supply must be removed for access to the voltage select switch (see figure

4).

MECHANICAL INSTALLATION

The 6119 monitor is designed to be mounted and secured in place on any flat surface by
four 10-32 X 1/2 inch screws into the bottom panel. See figure 3 for the hole pattern
required. (Model 6119 only)

OPTIONAL RACK MOUNT

As an option, the Model 6119-8 is provided with an all steel chassis and bezel assembly.
This option includes heavy duty slides and requires only 15.75 inches of panel space.
