LCD Display

h LCD display — The LCD displays the horizontal and vertical scanning rates of the input

signal, and indicates the horizontal and vertical centering status and limits.

LCD screen backlight

The LCD lights for 15 seconds at power-up and it remains lit as long as an input signal is

present at the selected input. To force the backlight to remain off at all times except at

power-up, set DIP switch 8 (No Backlight) to On (up) (see Rear Panel DIP Switches on

page 8).

Scan rate indication

When the interface is powered on, the LCD lights for 15 seconds while it determines

whether an input sync signal is present. If DIP switch 8 is set to On (up), the LCD lights

for three seconds only (see Rear Panel DIP Switches on page 8).

z If the interface does not detect an input sync signal, the LCD goes dark and displays

No Signal until the interface receives an active sync signal.

z If the interface detects an input sync signal, the LCD displays the horizontal and

vertical scan rates (sync frequencies) in the following format:

Hxxx.xxk

Vxxx.xHz

The ﬁrst line shows the horizontal rate in kiloHertz; the second line shows the

vertical rate in Hertz.

Centering indications

While the vertical (

{

) or horizontal (

[

) centering (shift) controls are being adjusted, the LCD

displays H-Shift or V-Shift. That message remains on the LCD (in place of the scan rates)

until the centering control has been inactive for 3 seconds. When a centering control reaches

its minimum or maximum limit, the LCD displays Min or Max on the line below H-Shift or

V-Shift.

Once the centering controls are no longer active, the centering settings are saved, and the

LCD displays the current scan rates.

If DIP switch 1 (DDSP) on the rear panel is set to On (up, see Rear Panel DIP Switches on

page 8) and a centering control is rotated, the LCD displays N/A DDSP On, and the image

does not shift on screen.
