VP-427A - Introduction 1

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 i

Go to www.kramerav.com/downloads/VP-427A 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 highperformance, 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 VP-427A 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.

VP-427A - Getting Started 3

3 Overview

The Kramer VP-427A is a receiver/scaler for HDBaseT twisted pair, HDMI, bidirectional RS-232 and IR signals. The unit receives an HDBaseT signal that it converts to HDMI, IR and passed RS-232 signals. It up- or down-scales the picture to match the resolution of the HDMI monitor.

The VP-427A also features:

An HDBaseT input

An HDMI output

A bidirectional RS-232 port for embedding/de-embedding control commands in the HDBaseT data stream

Infrared input and output ports for controlling devices over the HDBaseT data stream

Embedded audio supporting LPCM 2CH

Maintains constant sync on the output, even when the input video signal is lost or interrupted

A simultaneous analog audio output of the embedded HDMI audio

System range of up to 70m (230ft).

A built-in ProcAmp for convenient signal adjustment

An On-Screen Display (OSD) for easy setup and adjustment, accessible via the front-panel buttons

A non-volatile memory that retains the last settings used

A freeze button

A USB connector for firmware upgrading

The machine is fed from an external 5V DC source, making it suitable for field operation.

4 Connecting the VP-427A

i

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

VP-427A. After connecting your VP-427A, connect its power and then switch on the power to each device.

To connect the VP-427A as illustrated in the example in Figure 2 :

1. Connect the output from an HDBaseT transmitter (for example, a TP-582T) to the HDBT IN RJ-45 connector.

2. Connect the AUDIO OUT 3.5mm mini jack connector to an unbalanced stereo audio acceptor (for example, an amplifier).

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

4. Connect an IR receiver to the IR IN 3.5mm mini jack.

5. Connect the IR OUT 3.5mm mini jack to an IR emitter.

6. Connect the RS-232 9-pin D-sub connector to an RS-232 port (for example, a display).

7. Connect the 5V DC power adapter to the power socket and connect the

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

4.1 RS-232 Control over HDBaseT

You can connect to the transmitter/receiver system via an RS-232 connection using, for example, a PC. Note that a null-modem adapter/connection is not required.

To connect a PC via RS-232, connect the RS-232 9-pin D-sub rear panel port on the transmitter/receiver system unit via a 9-wire straight cable (only pin 2 to pin 2, pin 3 to pin 3, and pin 5 to pin 5 need to be connected) to the RS-232 9-pin D-sub port on your PC.

VP-427A - Connecting the VP-427A 7

Figure 2 shows RS-232 bidirectional control of the DVD that is connected to a

TP-582T.

4.2 IR Control Over HDBaseT

Since the IR signal on the TP-582T transmitter and VP-427A receiver is bidirectional, you can use a remote control transmitter (that is used for controlling a peripheral device, for example, a DVD player) to send commands (to the AV equipment) from either end of the transmitter /receiver system. To do so, you have to use the Kramer external IR sensor on one end (P/N: 95-0104050) and the

Kramer IR emitter cable on the other end (P/N: C-A35/IRE-10)

Two IR Emitter Extension Cables are also available: a 15 meter cable and a 20 meter cable.

The example in Figure 2 illustrates how to control the DVD player that is

connected to TP-582T using a remote control, via the VP-427A. In this example, the External IR Sensor is connected to the IR connector of the VP-427A and an IR

Emitter is connected between the TP-582T and the DVD player. The DVD remote control sends a command while pointing towards the External IR Sensor. The IR signal passes through the TP cable and the IR Emitter to the DVD player, which responds to the command sent.

5 Operating the VP-427A

The VP-427A is operated directly using the front panel buttons and the OSD menu

(see

Section ‎5.2

).

5.1 Operating the VP-427A from the Front Panel Buttons

During normal operation (without the OSD), the front panel buttons perform the following functions:

Pressing MENU opens the on-screen display (OSD) main menu (see

Section

‎5.2

), the next press closes the OSD

Pressing +/FREEZE freezes the display, the next press unfreezes the display

Pressing MENU and –/AUTO ADJUST together resets the display to 720p

Pressing ENTER and +/FREEZE together resets the display to XGA

5.2 Using the OSD

You can use the OSD to set a wide variety of parameters. When the MENU button is pressed, the main menu opens (see

Section ‎5.2.2

) allowing access to all the

device settings.

5.2.1 Operating the OSD from the Front Panel Buttons

While the OSD is open, the front panel buttons perform the following functions:

Pressing - and + move forward and backward through the menu items and decrement or increment the parameter values

Pressing ENTER selects and activates a menu item or accepts the parameter value set

Pressing MENU closes the OSD menu

The menu times out by default after 10 seconds. To change the OSD display time, adjust the OSD/TIMER parameter.

VP-427A - Operating the VP-427A 9

As an example of setting parameters, to increase the contrast on the display:

1. From normal operation, press MENU.

The OSD main menu appears on the screen.

2. Press the + or – button to highlight CONTRAST.

CONTRAST changes to green when highlighted.

3. Press ENTER.

The contrast value parameter changes to red.

4. Press the + button to increase the value (increase the contrast) or the – button to decrease the value (decrease the contrast).

The value ranges from 0 to 100.

5. Press ENTER to set the value.

The contrast value parameter changes back to white.

6. To return to normal operation, highlight EXIT and press ENTER, press

MENU, or wait until the menu times out.
