Introduction

Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we have redesigned and upgraded most of our line, making the best even better!

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.

Kramer VP-427X - Getting Started - 1

Go to www.kramerav.com/downloads/VP-427X or www.kramerav.com/downloads/VP-427X to check for up-to-date user manuals, application programs, and to check if firmware upgrades are available (where appropriate).

Achieving 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 VP-427X away from moisture, excessive sunlight and dust.

Safety Instructions

Overview

Congratulations on purchasing your Kramer VP-427X 4K HDBT/HDMI Receiver Scaler Switcher.

VP-427X is a high-performance auto-switcher receiver with integrated scaler for 4K HDMI™ over long-reach HDBaseT, with a local HDMI input and an HDMI output. VP-427X receives the HDBaseT signal from a compatible transmitter, converts it to an HDMI signal and up- or down-scales the picture to any resolution up to 4K@60Hz (4:4:4) set by the user or automatically matching the resolution of the display connected to the HDMI output.

Exceptional Quality

  • Auto Switcher Ease of Use — Automatically plays the switched source signal on the connected display according to user—configured preferences, such as auto-scan or last-connected input. When the user manually switches, by pressing a button, the auto switching is overridden.
  • Fast and clean AV Switching — Clean and instantaneous switching between inputs, with smooth, fade-through-black, uninterrupted transitions between presented content on the display, greatly enhancing end-users presentation experience.
  • High–Performance Scaling Experience — Built-in ProcAmp high-resolution scaling technology for optimal up or down image scaling and video signal auto-adjustment with output-connected display capabilities to gain end-users valuable high presentation experience.
  • HDMI Signal Switching — HDCP 2.2 compliant, supporting deep color, x.v.Color™, CEC, lip sync, HDMI uncompressed audio channels, Dolby TrueHD, DTS–HD, 2K, 4K, and 3D as specified in HDMI 2.0.
  • I–EDIDPro™ Kramer Intelligent EDID Processing™ — Intelligent EDID handling, processing, locking and pass-through algorithm ensures plug & play operation for HDMI source and display systems.

Advanced and User-friendly Operation

  • Display On/Off Operation — Meeting presentation is simplified by automatically turning ON/OFF a CEC-enabled display when the presentation source is plugged in / unplugged.
  • Convenient Unit Control and Configuration Options — Local control via front panel

source switching buttons and OSD menu. Distance control via RS-232 serial commands transmitted by a PC, touch screen system or other serial controller.

- Easy, Cost-effective Maintenance — Local firmware upgrade via USB connector.

- Easy and Elegant Installation — Compact MegaTOOLS™ fan-less enclosure for dropped-ceiling mounting, or side-by-side mounting of 2 units in a 1U rack space with the recommended rack adapter

Flexible Connectivity

- Wired and Wireless Auto Switcher — When the receiver is connected to a wireless connectivity device such as Kramer VIA, can automatically select between a wired source at the transmitter or the wireless source at the receiver.

- High Performance Standard Extension — Professional HDBaseT extension for providing long-reach signals over twisted-pair copper infrastructures. VP-427X is a standard receiver that can be connected to any market-available HDBaseT-compliant extension product. For optimum extension reach and performance, use recommended Kramer cables.

- Audio De-embedding — The digital audio signal passing—through to the HDMI output, is de-embedded, converted to an analog signal and sent to the stereo balanced analog audio output. This enables playing the audio on a locally connected professional audio system (such as DSP) and speakers, in parallel to playing it on the speakers connected to the AV acceptor device (such as TVs with speakers).

- Bidirectional RS–232 Extension — Serial interface data flows in both directions, allowing data transmission and device control.

Typical Applications

VP-427X is ideal for the following typical applications:

• Classrooms and lecture halls
- Meeting rooms
- Training facilities
• Collaborative classrooms
- Any space where BYOD support is required

Upgrading Firmware

Upgrade the firmware in any of the following ways:

  • Connecting the device to your PC and using Kramer K-UPLOAD software.
  • Via PROG USB port ① (see USB Firmware Upgrade (USB Format FAT32) on page 20).

USB Firmware Upgrade (USB Format FAT32)

To update the firmware via PROG USB port:

  1. Save VP_427X bin. file (for example, VP_427X_all_V*.bin) in USB flash driver and plug into PROG USB port.
  2. Press and hold MENU+ENTER buttons for about 3 seconds until both HDBT/HDMI INPUT LEDs blink.
  3. Continue holding buttons until both LEDs are lit consistently (this could take up to 60 seconds).
  4. Set the unit to factory reset (MENU>FACTORY>RESET ALL).
  5. Power off and remove the USB flash driver.

Kramer VP-427X - To update the firmware via PROG USB port: - 1

If the device is in USB mode but can't read the firmware file or if the USB flash driver is not connected, it reboots automatically after 10 seconds and exits the USB mode.

Kramer VP-427X - To update the firmware via PROG USB port: - 2

If the power drops during firmware upgrade, it automatically starts upgrading once the power is back.

If the power drops in the early stages of firmware upgrade, you need to start firmware upgrade again.

Protocol 3000 for VP-427X

Kramer devices can be operated using Kramer Protocol 3000 commands sent via serial or Ethernet ports.

Understanding Protocol 3000

Protocol 3000 commands are a sequence of ASCII letters, structured according to the following.

- Command format:

PrefixCommand NameConstant (Space)Parameter(s)Suffix
#Command_Parameter

- Feedback format:

PrefixDevice IDConstantCommand NameParameter(s)Suffix
~nn@CommandParameter

- Command parameters – Multiple parameters must be separated by a comma (,). In addition, multiple parameters can be grouped as a single parameter using brackets ([ and ]).

- Command chain separator character – Multiple commands can be chained in the same string. Each command is delimited by a pipe character (|).

- Parameters attributes – Parameters may contain multiple attributes. Attributes are indicated with pointy brackets (<...>) and must be separated by a period (.).

The command framing varies according to how you interface with VP-427X. The following figure displays how the # command is framed using terminal communication software (such as Hercules):
