Connecting Display Module to MBC-RGB Buffer
Before connecting to power, proceed by connecting the display module to the
MBC-RGB Buffer assembly as described below.
Connect the MBC-IBM 3482-87 cable (1) from
the logic module to the MBC-RGB Buffer
(2) as shown in Figure 10. Connect the
MBC-RGB Buffer cable (3) to the
analog input of the selected
interface. The MBC-RGB
Buffer is compatible with
the RGB 118, 118 Plus,
120, 108 Plus, and 202
Plus interfaces.
Restore power and adjust
the respective interface
features to obtain the best
visual presentation.
Special Note: The “Blue Enhance” control is provided on the MBC-RGB Buffer
for the purpose of “brightening” the primary blue color within the color palette in
order to attain a color display similar to the IBM terminal. Increasing the bright-
ness (de-saturating) of the primary blue allows easy viewing of blue detail on
projection applications. As the Blue Enhance control is advanced, some effect
can be seen on magenta graphics. The magenta will tend to de-saturate. This is
a normal side effect of the Blue Enhance feature. Adjust the Blue Enhance for
best overall performance.
At this time, adjust the blue enhance control on the MBC-RGB Buffer to achieve
the desired blue color. This completes installation of the IBM 3482/87 Interface
Kit.
