Color Monitor
Resolution for the high resolution color monitor is 1280 x 1024
pixels. Adding additional color monitors is model dependent.
The same monitor is used for all the OIC42 models. Refer to
Table
for the monitor part number. Refer to the appropri-
ate OIC model in
for the monitor cable connections.
NOTE: The monitors are autosensing and do not need to be
switched if the power to the cabinet is 120 V or 240 V. However, if
other monitors are used, they may need to be switched to prevent
damage from over voltage or under voltage.
A video cable connects the monitor to the monitor port on the
CPU. Labels R, G and B represent red, green and blue on the
monitor end of the cable.
A 9-pin D subconnector connects an external brightness, con-
trast and degauss control at AUX 1 of the monitor connection
panel.
Screen brightness, contrast, width and height controls are
mounted on the monitor back connection panel for all models.
There are two degauss reset switches; one is located on the
monitor connection panel and the other is located on the
power entry panel.
Monitor wiring connector location may be slightly different for
each OIC console. Figure
identifies the color monitor
connections.
