7. CONNECTION TO CNC PERIPHERALS
Fine adjustment of the video signal is supported to enable its use with
color liquid crystal displays and plasma displays. This adjustment is
necessary to compensate for errors resulting from the combination of NC
devices and cables.
Adjustment of the video signal is necessary if you have replaced the
display unit, cable, or a hardware component of the display circuit in the
NC, either as part of regular field maintenance or to correct a failure.

Analog color liquid crystal display: Jumper pin TM1
Change the jumper pin to another side.
Normally one of these settings will eliminate flicker.
Plasma display: Switch SW1
1 Change the jumper pin and search for a range such that flicker is
2 If you find that flicker is eliminated by two or more different
settings, select the setting approximating to the midpoint of those
Example : If flicker is eliminated by all of settings 2 to 6, select 4.

Plasma display : Switch SW2
1 The screen can be shifted horizontally in units of dots.
2 Adjust the horizontal position such that the entire screen is visible.
Only one setting can successfully realize this positioning.
Do not attempt to change any controls or settings other than those
