Note: For video mode 720 x 400 missing video rows and columns are allowed. This is a text mode only. Performance is acceptable if characters as defined section 1.2.1 are legible. Missing row or columns at the edge of the display is acceptable as long as characters remain legible.

5 DC Power Input Requirements

5.1DC Power Input Lines

The DC Power Input Connector consists of two (2) positions wired numerically and supplied attached to the LC1200R as a chassis mounted connector per definitions listed in Table 7.

5.2DC Input Voltage / Current

DC Input Voltage: 12 V DC nominal, +/- .4 V DC.

Over the specified input voltage range:

•No loss of image synchronization occurs.

•White display luminance level is within 10% of luminance at nominal input voltage.

•DC Input Current: 4.3 amp maximum current draw (12.4-vdc applied) steady state conditions.
