Getting Started 2.1 Quick Start This quick start chart summarizes the basic setup and operation steps.
Overview 3 Overview The Kramer VM-12HDCP is an HDCP (High-Bandwidth Digital Content Protection) compatible 1:12 distribution amplifier for DVI-D (Digital) signals. Since high-resolution DVI signals are very sensitive to cable quality and to PCB layout, the VM-12HDCP uses a uniquely designed PCB which includes all buffering, conditioning and amplifying circuitry to provide 12 high-level output signals.

Connecting a VM-12HDCP 1:12 DVI Distributor 6 Connecting a VM-12HDCP 1:12 DVI Distributor To connect the VM-12HDCP as illustrated in the example in Figure 2, do the following 1: 1. Connect a DVI source (for example, a computer) to the INPUT connector. 2. Connect up to 12 OUTPUT connectors 2 to up to 12 DVI acceptors. For example, the: OUTPUT 1 connector to DVI acceptor 1 (for example, a projector) OUTPUT 12 connector to DVI acceptor 12 (for example, a display) 3.
Acquiring EDID Figure 2: Connecting a VM-12HDCP 1:12 DVI Distributor 7 Acquiring EDID The VM-12HDCP initially operates with the default EDID. This means that you can turn ON the power before connecting any of the acceptors or the source. This section describes the two EDID operation states: • Simple (see section 7.1) • Normal (see section 7.
Acquiring EDID 7.1 The Simple Operation State In the Simple operation state, the READ and SELECT front panel buttons are disabled, and the default EDID is passed directly to the input. To enter the Simple Operation State, turn the machine ON while pressing the READ button. The LEDS 3 and 4 flash three times 7.2 The Normal Operation State In the Normal operation state, you can toggle between the following working modes: • Sending the EDID from a selected output to the input (see section 7.2.
Technical Specifications The default EDID is stored in the non-volatile memory when the READ button no longer illuminates as well as the output LEDs. 7.2.3 Acquiring the Auto EDID To acquire the Auto EDID, do the following: 1. Press the SELECT button several times until the OUTPUT LEDs flash in sequence. 2. Press the READ button. The READ button illuminates.
