Introduction 1 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! Our 1,000-plus different models now appear in 11 groups 1 that are clearly defined by function.
Getting Started 2.1 Quick Start This quick start chart summarizes the basic setup and operation steps.
Overview 3 Overview The Kramer VM-2HDCP is an HDCP (High-Bandwidth Digital Content Protection) 1 compatible 1:2 distribution amplifier for DVI-D (Digital) signals. Since high-resolution DVI signals are very sensitive to cable quality and to PCB layout, the VM-2HDCP uses a uniquely designed PCB which includes all buffering, conditioning and amplifying circuitry to provide two high-level output signals.
Overview 3.2 Defining EDID The Extended Display Identification Data (EDID 1) is a data-structure, provided by a display, to describe its capabilities to the source. The EDID enables the VM-2HDCP 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. 3.

Connecting a VM-2HDCP 1:2 DVI Distributor Figure 4: Connecting a VM-2HDCP 1:2 DVI Distributor 5.1 Acquiring the EDID Initially, the VM-2HDCP operates with the factory default EDID 1. This lets you connect the power before connecting either of the acceptors or the source. You can acquire: • The Default EDID (both output LEDs blink) • The EDID from One Output (the relevant output illuminates) You can also acquire the Clone EDID which copies the EDID data from the acceptor bit-by-bit.
Connecting a VM-2HDCP 1:2 DVI Distributor 5.1.1 Acquiring/Changing the EDID You can work with the default EDID or acquire or change an EDID via one of the connected outputs. Use the EDID Setup button to acquire the output EDID information. To acquire or change the EDID of a new output display: 1. Connect the power supply. The ON LED lights. 2. Connect the new output display device. 3. Press and hold the EDID button for more than three seconds and release.
