Overview

3 Overview

The VP-4x8AK is a high performance 4x8 computer graphics video matrix

switcher for high-resolution video and stereo audio signals. The VP-4x8AK

is HDTV compatible and lets you simultaneously route any or all of the four

inputs to any or all of the eight outputs and to loop each input to an additional

output.

In particular, the VP-4x8AK 4x8 VGA / UXGA / Audio Matrix Switcher

features:

•Kramer’s innovative integrated sync processing; Kr-isp® technology that

lets you achieve a sharp, stable image when the sync level is too low, by

restoring the sync signal waveform

•A video bandwidth of over 360MHz that ensures transparent performance

even in the most critical applications

•12 preset memory locations for quick access to common video and audio

configurations and audio gain status for each output

•Automatic detection of the connected input signals (the respective button

illuminates)

•A delayed switching mode (ranging from 0 to 3.5sec1

•DC-coupled video inputs and outputs

) for clean

transitions when switching between non-genlocked sources

•Audio-follow-video and breakaway options

•Four stereo unbalanced stereo audio input signals on 3.5mm mini plugs

•Eight balanced stereo audio output signals on 5-pin terminal block

connectors

•Audio level control buttons for adjusting the signal level of each input

and each output

•Measurement and indication of the audio level for each input and output,

in relative dB

•A TAKE button, which allows you to place multiple switches in a queue

and then activate them simultaneously with one touch of this button

•A LOCK button to prevent tampering with the front panel

•Supports DDC (Display Data Channel2

•Control via embedded Web pages

) communication between input 1

and output 1 high-density 15-pin HD connectors on pins 12 and 15

1 In increments of 0.5sec

KRAMER: SIMPLE CREATIVE TECHNOLOGY

Overview

Control the VP-4x8AK using the front panel buttons, or remotely via:

•RS-485 or RS-232 serial commands (using Kramer 2000 and 3000

protocols) transmitted by a touch screen system, PC, or other serial

controller

•The Kramer infrared remote control transmitter or infrared remote

extension cable transmitter (optional)

•The ETHERNET

The VP-4x8AK is dependable, rugged, and fits into two vertical spaces (2U)

of a standard 19” professional rack.

To achieve the best performance:

•Use only good quality connection cables1

•Avoid interference from neighboring electrical appliances that may

adversely influence signal quality and position your Kramer VP-4x8AK

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).

3.1 Terminology Used in this User Manual

Table 1defines some terms that are used in this user manual:

Table 1: Terminology Used in this User Manual

Term

Definition

802.3

The standard specification for ETHERNET that is maintained by the Institute of Electrical and

Electronics Engineers (IEEE).

Dynamic Host Configuration

Protocol (DHCP)

Allows the network administrator to distribute IP addresses from a central point and

automatically send a new IP address when an Ethernet point is plugged into a different

network location.

Gateway

A network position serving as an entry to another network. On the Internet, a node or

stopping point can be either a gateway node or a host (end-point) node.

IP Address

A 32-binary digit number that identifies each sender or receiver (within a network via a

particular server or workstation) of data (HTML pages or e-mails) that is sent in packets

across the Internet. Every device connected to an IP network must have a unique IP

address. This address is used to reference the specific unit.

Local Area Network (LAN) Computers sharing a common communications line or wireless link, which often share a

server within a defined geographic area.

Media Access Control

(MAC) Address

A computer's unique hardware number (or address) in a LAN or other network. On an

Ethernet LAN, the (MAC) address is identical to the Ethernet address.

Transmission Control

Protocol/Internet Protocol

(TCP/IP)

The basic communication language or protocol of the Internet that breaks the message into

appropriately sized packets for the network, and can be used as a communications protocol

in an intranet or an extranet.

Your VP-4x8AK 4x8 VGA / UXGA / Audio Matrix Switcher

3.2 DDC Support

When establishing a VGA connection between a PC or laptop and a display

device, a set of parameters known as EDID is exchanged between them, which

is carried over the DDC channel. In some PC graphic cards and laptops, this

information exchange is essential for proper VGA OUT operation.

3.3 Defining EDID

The Extended Display Identification Data (EDID1

4 Your VP-4x8AK 4x8 VGA / UXGA / Audio Matrix Switcher

) is a data-structure,

provided by a display, to describe 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, the product type, the timing data supported by the

display, the display size, luminance data and (for digital displays only) the

pixel mapping data.

UXGA / Audio Matrix Switcher.
