LCD-841DS Instruction Sheet
The LCD-841DS is a rack mountable unit that has two 8.4" active matrix LCD panels.
These panels have 800 x 600 pixels making them true high-resolution screens with a
brightness of 350 candle luminance. Each panel has a S-Video, composite video, SDI
and VGA input with active loop through feature, and auto recognition for NTSC or PAL.
For added flexibility, an independent 3 color tally system is provided for each panel.
Each of the two screens have individual front mounted source selector buttons with
color bar generator and controls for color, tint, brightness and contrast on menu screen.
The unit includes power supply, and fits into any standard EIA 19" rack, at 4U height.
Although the LCD-841DS is a sophisticated blend of digital and analog technologies,
its operation is fairly straightforward. However, it is important to take note of the
following:
1.
Because the LCD-841DS must resample and resize every incoming signal;
when switching functions, it may be necessary to wait up to a second for the unit
to lock on to the selected function.
2.
The LCD-841DS has been designed to fit in a 4U space on your rack.
It may be necessary to center the unit up or down in order not to touch any
adjacent units in your rack when tilting unit up or down.
3.
Be sure not to apply any pressure on the LCD panels, they are fragile and can break.
Scratched, cracked or broken LCD screens are
not
covered by our warranty.
4.
The LCD-841DS uses 12VDC, 3.0amp regulated power. Be sure that these
specifications are met when using a power supply other than the one supplied
with the unit.
The center pin on the DC power connector for the LCD-841DS is the POSITIVE terminal
and the outside ring is NEGATIVE. Any battery operation of the LCD-841DS must have
this polarity configuration.
5.
The
LCD-841DS
is a rack mountable unit that has two independently controlled 8.4"
active matrix LCD panels with loop through capability. These high-resolution panels
have a pixel count of 800x600 and are rated at a very bright 350 candle luminance.
Each panel has an S-video, Composite Video, SDI with NTSC/PAL auto-recognition
and a VGA input available. Each of the two screens has a built-in color bar generator,
controls for brightness, color, tint and contrast, and a selectable under scan/normal
(over-scan) feature on menu screen. A built in 3 color tally system is also provided
for each screen. Unit comes complete with power supply, and fits into any standard
EIA 19" rack, at 4 rack spaces height.
6.
The Digital and Analog inputs on the rear of the panel are 75 Ohm self-terminated.
The LCD-841DS is also equipped with a 10-bit D/A converter that converts the SDI
input from that channel. This D/A converter uses the SMPTE 259M standard and is
re-clocked.
7.
The loop through feature uses active components and is always active as long as
power is supplied to the unit regardless of the monitor being On or Off.
8.
The VGA input of the LCD-841DS is accessed via the DB-15 connector on the back of
the unit labeled ‘VGA’. This input accepts from 640x480 up to 1280 x 1024 with
refresh rates from 60Hz to 85Hz. The unit will scale any input up or down to fit onto
the screen.
The native resolution of the LCD-841DS panel is 800 x 600.
