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 accessible 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 3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 Mean-

Time-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 switch selection. This allows

the use of the monitor with other devices on the output of the raster engine or video

switch.

MASTERSYNC MONITOR SPECIFICATIONS

DEFLECTION

SCAN RATE RANGES: Horizontal scan rates from 15 to 90 kHz, 40 to 120 Hz non-

interlaced and 20-60 Hz interlaced vertical. Automatic selection to match input video

format.

RETRACE TIME: Maximum of 3.0 microseconds horizontal and 400 microseconds

vertical.

HORIZONTAL AND VERTICAL SYNC: Automatic detection and selection of

composite (3 wire), separate video and mixed sync (4 wire), and separate video, vertical

and horizontal sync (5 wire). Polarity: Negative only for three wire operation. Positive or

negative for four and five wire operation. Separate sync inputs are ECL and TTL

compatible 1.0 to 4.0 volts peak to peak.

LINEARITY: Horizontal and vertical nonlinearity (when measured using the EIA Standard

Ball Chart Method or equivalent) is better than +1% raster height.

RASTER SIZE REGULATION: Raster size change caused by changes in CRT beam

current from 0-100% APL (approximately 0 to 200 Microamps) will be less than 0.5%.

GEOMETRIC DISTORTION: No point on the raster (i.e., pixel) is displaced from its

proper position by more than 1% of raster height within a 9 inch circle (Model 6115 &

6116) and within an 11 inch circle (Model 6119 & 6120) and no more than 1.5%

elsewhere.

MISCONVERGENCE: Within a centrally located circle of six inch diameter

misconvergence will be less than 0.2mm and elsewhere will be less than 0.4mm when

measured as the worse case between any two colors.

POWER REQUIREMENT

A.C. POWER: Input voltage 90-132 v.a.c. or 180-264 v.a.c. switch selectable inside the

monitor, 47 to 63 Hz. Power Consumption 150 Watts maximum.
