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 integra ted sync processing; Kr-isp® technol ogy that

lets you achieve a sharp, stable image when the sync level is too low, by restori ng 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 3.5sec

• DC-coupled video inputs and outputs

) for clean

transitions whe n switchi ng between non-ge nlocked 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 t erminal block

connectors

• Audio level control butto ns for adjusting t he signal l evel of each input

and each output

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

in relative dB

• A TAKE button, which allows you to place multiple s witc hes in a queue

and then a ctivate t hem simul t aneous ly with one touch of this b ut ton

• A LOCK button to prevent tampering with the front panel

• Supports DDC (Display Data Channel

• Control via embedded Web pages

Overview

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

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

protocols) trans mitted 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 cables

• Avoid interference from neighboring electrical appliances that may

adversely influe nce signa l quality and position your Kramer VP-4x8AK away from moisture, excessive sunlight and dust

to avoid interference, deterioration in signal q uality due to poor matching, and elevated noise levels (often associated with low quality cables).

3.1 Terminology Used in this User Manual

Table 1 defines 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 Defi n ing EDID

The Extended Display Identification Data (EDID

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

) is a data-structure, provided by a displa y, to de scribe its capabilities to a grap hics 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, l uminance data and (for digi ta l displays only) the pixel mapping data.

This section describes what to do before installing in a rack and how to rack mount.

Using the VP-4x8AK

6 Using the VP-4x8AK

This section describes how to:

• Connect the VP-4x8AK rear panel (see Section

6.1)

• Connect a balanced stereo audio output (see Section

6.2)

• Connect the VP-4x8AK to a controllin g d e vice via RS-232 (see Section

6.3), RS-485 (see Section 6.4) and/or the ETHERNET (see Section 6.5)

• Set the switching delay time (see Section

6.7)

• Set the machine number (see Section

6.8)

• Connect several VP-4x8AK machines (see Section

6.9)

6.1 Connecting the VP-4x8AK Rear Panel

To connect

Figure 3 the VP-4x8AK, as illustrated in the example in , do the

following

1. Connect up to four VGA/UXGA computer graphics sources to the INPUT

15-pin HD connectors.

2. Connect up to four unbalanced stereo audio sources (for example, the audio

source of the computer, or a stereo audio source) to the four INPUT 3.5mm mini connectors.

3. Connect up to four VGA/UXGA output acceptors to the LOOP connectors

6. If required, you can connect a PC and/or controller to the:

 RS-232 port (see Section

6.3)

 RS-485 port (see Section

6.4)

 ETHERNET (see Section

6.5)

7. Connect the power cord

Figure 3 (not shown in ).

1 You do not need to connect all inputs and outputs 2 Switch OFF the po wer on each device before connecting it to your VP-4x8AK. After connecting your VP-4x8AK, switch on its power and then switch on the power on each device. DO NOT push in the rear panel Flash Program “PROG” button , it is only used for upgrading to the latest Kramer firmware (see Section
