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.
