VS-311H - Getting Started

2 Getting Started

We recommend that you:

Unpack the equipment carefully and save the original box and packaging

materials for possible future shipment

Review the contents of this user manual

Go to http://www.kramerelectronics.com/support/product_downloads.asp

to check for up-to-date user manuals, application programs, and to check if

firmware upgrades are available (where appropriate).

2.1 Achieving the Best Performance

To achieve the best performance:

Use only good quality connection cables (we recommend Kramer high-

performance, high-resolution cables) to avoid interference, deterioration in

signal quality due to poor matching, and elevated noise levels (often

associated with low quality cables)

Do not secure the cables in tight bundles or roll the slack into tight coils

Avoid interference from neighboring electrical appliances that may adversely

influence signal quality

Position your Kramer VS-311H away from moisture, excessive sunlight and

dust

This equipment is to be used only inside a building. It may only be

connected to other equipment that is installed inside a building.

2.4 Terminology Used in this User Manual

The following table defines some terms that are 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.

VS-311H - Overview

3 Overview

The VS-311H is a high-performance 3x1 HDCP- compatible automatic switcher for

HDMI signals, digital audio (S/PDIF) signals and stereo audio signals.

The VS-311H switches any one of three HDMI, HDCP compliant sources to a

single display device, on HDMI connectors with the corresponding:

Digital audio (S/PDIF) input signals switched to an S/PDIF output, on RCA

connectors and/or

Unbalanced stereo audio input signals on 3.5 mini-jack connectors switched

to an unbalanced stereo audio output on a 3.5 mini-jack connector, as well

as to a balanced stereo audio output on a 5-pin terminal block connector

The VS-311H can operate either in the manual mode or in the auto mode.

In the manual mode, the VS-311H acts as a regular switcher, switching the input

video and audio signals to the output via the three front panel INPUT SELECT

buttons.

In the auto mode, you can switch any input to the output via the three front panel

INPUT SELECT buttons, but once the selected video signal is lost, the machine

automatically switches to the highest priority input, according to the input priority

setup. The VS-311H switches back to the primary input when an HDMI signal is

detected on that input.

When selecting an INPUT SELECT button, via the manual or auto mode, that

button lights. Pressing an illuminated button deselects that input and that button no

longer lights.

The VS-311H is housed in a desktop-sized enclosure and is 12V DC fed.

Control the VS-311H using the front panel buttons, or remotely via:

RS-232 serial commands transmitted by a touch screen system, PC, or other

serial controller

The Kramer infrared remote control transmitter

The ETHERNET

Remote control contact closure

4 Connecting the VS-311H

Always switch off the power to each device before connecting it to your

VS-311H. After connecting your VS-311H, connect its power and then

switch on the power to each device.

To connect the VS-311H as illustrated in the example in Figure 2:

1. Connect an HDMI source (for example, an HDMI DVD player) to the IN 1

HDMI connector and connect the digital audio input to the IN 1 S/PDIF RCA

connector.

You can also connect a DVD player with a DVI connector, using a DVI-HDMI adapter to

transfer video signals. Alternatively you can connect analog audio to the 3.5 mini-jack

connector

2. Connect an HDMI source (for example, an HDMI set top box source) to the

IN 3 HDMI connector and connect the digital audio input to the IN 3 3.5 mini-

jack connector or you can connect it to the S/PDIF RCA connector.

3. Connect the OUT HDMI connector to the HDMI acceptor (for example, an

HDMI plasma display).

4. Connect the AUDIO OUT S/PDIF RCA connector and the AUDIO OUT 3.5

mini-jack connector to a digital audio acceptor (for example, an AV receiver).

If the inputs are connected only to the 3.5 mini-jack connectors, connect the AUDIO

OUT 3.5 mini-jack connector and/or the BALANCED OUT terminal block connector

only.

5. Set the PRIORITY SETUP DIP-switches (see Section 4.1)

6. If required, connect a PC and/or controller to the RS-232 port (see

Section 4.4) and/or the ETHERNET port (see Section 4.5).

7. If required, connect the contact closure remotecontrol PINs (see Section 4.3).

8. Connect the 12V DC power adapter to the power socket and connect the

adapter to the mains electricity (not shown in Figure 2).
