Video, Audio, VGA/XGA Processors; GROUP 4: Interfaces and Sync Processors; GROUP 5: Twisted Pair Interfaces;
GROUP 6: Accessories and Rack Adapters; GROUP 7: Scan Converters and Scalers; and GROUP 8: Cables and Connectors
2 Digital Visual Interface was designed to provide the industry with a single, universal digital interface (primarily to provide a
digital connection between a PC and a display device). It is now considered the industry standard digital graphics interface
3 As an option, you can purchase the Kramer VA-50P 6 Port Universal 12-Volt Power Supply, enabling you to supply power
to up to 6 Kramer devices that require 12VDC

In particular, the 840 includes:
A DVI-D output
Seven control buttons: SVGA, XGA, SXGA, UXGA, Wide (On),
PATTERN – and PATTERN +
A 7-segment display that indicates the pattern number
An on board EERROM that saves the last setting used
Note that only the digital signal (DVI-D) is available on the DVI connector.
To achieve the best performance:
Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise levels
(often associated with low quality cables)
Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer 840 away from
moisture, excessive sunlight and dust

5 Using Your 840 DVI Pattern Generator
This section describes how to:
Connect the 840 DVI Pattern Generator (see section 5.1)
Operate the 840 DVI Pattern Generator (see section 5.2)
Interpret each Pattern Number Definition (see section 5.3)
5.1 Connecting Your 840 DVI Pattern Generator
To connect the 840 DVI Pattern Generator, do the following1:
1. Connect the OUTPUT connector to a DVI acceptor, for example, a flat
panel LCD display (as Figure 2 illustrates), or a projector or plasma
screen.
2. Connect the 12V DC power adapter (wall transformer) to the 12V DC
socket and connect the transformer to the mains electricity.
Figure 2: Connecting the 840 DVI Pattern Generator
1 Switch OFF the power on the DVI acceptor before connecting it to your 840. After connecting your 840, switch on its
power and then switch on the power on the DVI acceptor

5.2 Operating Your 840 DVI Pattern Generator
Several patterns (see Table 3) are programmed into the 840 DVI Pattern
Generator, in order to assess various aspects in the flat panel LCD display,
projector, Plasma screen or cable. For example, the 840 tests a:
Flat panel LCD display1 by testing if all the pixels illuminate with the
correct amounts of light, linearity, and high frequency response
Projector, verifying that the colors are as required, tuning the size and
focus of the picture
DVI cable, checking the quality2 of the colors, both separately and together
Plasma screen, to check the black level of the plasma monitor (use
PATTERN 00 to generate the black screen)
To operate the 840 DVI Pattern Generator, do the following:
1. Press the appropriate PATTERN button (PATTERN + to display the next
pattern or PATTERN – to display the previous pattern) to generate the
required pattern. The PATTERN NUMBER 7-segment Display shows the
selected pattern number.
2. Observe the output on your flat panel LCD display, projector or plasma
screen.
