3 Overview
The VP-31KSi routes one of three video and audio inputs to the video and audio
(balanced or unbalanced) outputs. It also converts the video and audio signals into
a TP (Twisted Pair) signal for transmission over TP cable to any compatible TP
receiver (for example, the Kramer TP-120).
In particular, the VP-31KSi:
• Features a very high video bandwidth ensuring transparent UXGA
performance
• Features audio-follow-video (AFV) in which all operations relate to both the
video and the audio channels, or the audio breakaway option, in which video
and audio channels are switched independently
• Includes a volume control
• Includes the Kramer innovative integrated sync processing Kr-isp™
technology, which lets you achieve a sharp, stable image even when the
sync level is too low, by restoring the sync signal waveform
• I-EDIDPro™ Kramer Intelligent EDID Processing™ – Intelligent EDID
handling & processing algorithm ensures Plug and Play operation for analog
systems
• Supports the cascading of up to eight devices to provide a single virtual
switcher with up to 17 inputs
• Supports the Kramer Remote Step-In Panels (for example, the SI-1VGA,
WSI-1VGA or SI-VGAT) for remote inputs and remote step-in control
You can control the VP-31KSi using the front panel buttons, or remotely via:
• RS-485 or RS-232 serial commands transmitted by a touch screen system,
PC or other serial controller
• Ethernet over a LAN using a Web browser
• Kramer Remote Step-in Panels (for example, the SI-1VGA or SI-VGAT)
• The Kramer RC-IR3 Infrared Remote Control Transmitter
• Remote, contact closure switches
3.1 Recommendations for Best Performance
To achieve the best performance:
• Use only high quality connection cables
1
• Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer
VP-31KSi away from moisture, excessive sunlight and dust
to avoid interference, deterioration
in signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables).

3.2 Defining EDID
The Extended Display Identification Data (EDID
1
) is a data-structure, provided by
a display that describes its capabilities to a graphics card (that is connected to the
display’s source). The EDID enables the PC or laptop to “know” what kind of
monitor is connected to the output. The EDID includes the manufacturer’s name,
product type, timing data supported by the display, display size, luminance data
and (for digital displays only) pixel mapping data.

1. Connect up to three
2
Remote Step-in Panels (for example, the SI-1VGA or
SI-VGAT) to the VP-31KSi 15-pin HD VIDEO INPUT connectors
3
2. Connect up to three UXGA computer graphics sources to the SI-1VGA
15-pin HD video connectors.
and to
the 3.5mm mini jacks (from 1 to 3).
3. Connect up to three unbalanced audio sources to the 3.5mm mini jack audio
connectors on the SI-1VGA panels.
4. Connect the 15-pin HD VIDEO OUTPUT connector to a UXGA acceptor (for
example, a projector).
5. Connect the RJ-45 CAT 5 OUT connector to a compatible TP receiver (for
example, the Kramer TP-120).
6. Connect either, but not both:
the unbalanced audio 3.5mm AUDIO OUTPUT jack to an unbalanced
audio acceptor (for example, power amplifier)
—OR—
the balanced audio 5-pin terminal block (see Section
5.1) to an audio
acceptor (not shown in
Figure 3)
7. Connect up to three remote, contact closure input selection switches to the
REMOTE terminal block (see Section
5.2).
8. Connect a PC over a LAN to the Ethernet for remote operation.
9. Set the DIP-switches (see Section
5.6.1) for remote operation. You can
connect a PC and/or controller to the:
RS-232 port (see Section
5.3)
RS-485 port (see Section
5.6.1)
10. Connect the power adapter to the device and to the mains electricity.
5.1 Connecting the Balanced/Unbalanced Stereo Audio Output
This section illustrates how to wire the devices to the balanced audio output:
• A balanced stereo output connection, see
Figure 4
• An unbalanced stereo output connection, see
Figure 5
1 Be sure that the power is switched off on each device before connecting it to your VP-31KSi. After connecting all the devices to your
VP-31KSi, switch on the power of the VP-31KSi, and then switch on the power of each device
2 You do not have to connect all the inputs
3 The cable used must connect all 15 pins

5.2 Connecting Remote Contact Closure Input Selection Switches
You can connect remote input selection switches to the Remote terminal block on
the rear panel of the VP-31KSi which enables you to remotely activate the relevant
input.
The following example (see
Figure 6) illustrates three switches (A, B and C)
connected to remotely control inputs 1, 2 and 3 respectively (up to three switches
can be connected). Pressing switch A causes input 1 on the VP-31KSi to be the
active input, pressing switch B causes input 2 to be the active input, and pressing
switch C causes input 3 to be the active input.

To connect remote input selection switches as the example illustrated in
Figure 6:
1. Connect Switch A to pins 1 and G (ground) on the terminal block.
2. Connect Switch B to pins 2 and G on the terminal block.
3. Connect Switch C to pins 3 and G on the terminal block.
