3 Overview
The VP-81KSi routes any input to both outputs, using 15-pin HD female connectors
for the computer graphics video signals, a 3.5mm mini jack for the unbalanced stereo
audio Output 1 signal, and a detachable terminal block connector for the balanced
stereo audio Output 2 signal.
In particular, the VP-81KSi:
• Has a very high video bandwidth ensuring transparent WUXGA performance
• Features audio-follow-video (AFV) in which all operations relate to both the
video and the audio channels, or audio breakaway option, in which video and
audio channels are switched independently
• Features 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
• Up to eight units can be cascaded to provide a single “virtual” switcher with
up to 57 inputs
• Supports the SI-1VGA Remote Step-in Panel for remote inputs and remote
step-in control
You can control the VP-81KSi 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
• The SI-1VGA Remote Step-in Panel
• The Kramer RC-IR3 Infrared Remote Control Transmitter or infrared remote
extension cable transmitter (optional)
• Remote, contact closure switches
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 VP-81KSi away from moisture,
excessive sunlight and dust

3.1 Defining EDID
1
The Extended Display Identification Data (EDID
) 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.

Defining the VP-81KSi 8x1 UXGA/Audio STEP-IN Switcher
4.1 Using the IR Transmitter for the VP-81KSi
You can use the RC-IR3 IR transmitter to operate the machine via the built-in IR
receiver on the front panel or, instead, via an optional external IR receiver
external IR receiver can be located 15m (49ft) away from the machine. This
distance can be extended to up to 60m (197ft) when used with three extension

cables
Before using the external IR receiver, be sure to arrange for your Kramer dealer to
insert the internal IR connection cable

with the 3.5mm jack that fits into the
REMOTE IR opening on the rear panel. Connect the external IR receiver to the
REMOTE IR 3.5mm jack.

6.2 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-81KSi 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 controlled inputs 1, 2 and 3 respectively (up to eight
switches can be connected). Pressing switch A causes input 1 on the VP-81KSi 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.
