Jumper JP3 on the operator panel keyboard interface is used to determine
if the keyboard interface module is attached to a monochrome or color
operator panel (note these keyboard configurations are different). This
jumper comes preset from the factory in the correct position for your
operator panel. Adjustment of this jumper should only be made when
replacing the operator panel keyboard interface module.
Set the color or monochrome operator panel jumper (JP3) to match the
type of operator panel you have. The following table illustrates proper
setting of JP3.

Monitor intensity is controlled by adjusting the contrast on monochrome
and color CRT systems. No intensity adjustments are available for the flat
operator panels.
Monitor intensity adjustment is typically not required on the operator
panels as they are adjusted to an acceptable level before shipping from the
factory. In the event that you think you must alter the monitor intensity use
