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 video, audio, presentation, and broadcasting professionals on a daily basis.
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 2.1 Go to http://www.kramerelectronics.com to check for up-to-date user manuals, application programs, and to check if firmware upgrades are available (where appropriate).
2.2 Safety Instructions ! 2.3 Caution: There are no operator serviceable parts inside the unit Warning: Use only the Kramer Electronics input power wall adapter that is provided with the unit Warning: Disconnect the power and unplug the unit from the wall before installing Recycling Kramer Products The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC aims to reduce the amount of WEEE sent for disposal to landfill or incineration by requiring it to be collected and recycled.
3 Overview Your Kramer VP-211K is a high performance 2x1 automatic switcher for computer graphics video (UXGA) and stereo audio signals. The VP-211K detects the presence of the active VGA-type input signal from either IN 1 (the default) or IN 2—depending on how the DEFAULT INPUT switch is set, as Section 4.2 describes—and automatically routes it to the acceptor connected to the UXGA OUT and the AUDIO OUT connectors.
3.1 Defining the VP-211K Automatic UXGA / Audio Switcher This section defines the VP-211K. Figure 1: VP-211K Automatic UXGA / Audio Switcher # Feature 1 UXGA LOOP OUT 15-pin HD Connector Connect to an additional monitor 2 UXGA OUT 15-pin HD Connector Connect to the computer graphics video acceptor 3 AUDIO OUT 3.5mm mini-jack Connector Connect to an unbalanced stereo audio acceptor 4 REMOTE IN 1 and IN 2 Terminal Block Connectors Connect to a contact closure switch, see Section 4.
4 Connecting the VP-211K i Always switch off the power to each device before connecting it to your VP-211K. After connecting your VP-211K, connect its power and then switch on the power to each device. To connect the VP-211K as illustrated in the example in Figure 2: 1. Connect a UXGA/audio source (for example, a PC graphics card) to the UXGA IN 1 15-pin HD connector and to the AUDIO IN 1 mini plug connector. 2.
Figure 2: Connecting the VP-211K Automatic UXGA / Audio Switcher 4.1 Connecting the REMOTE Terminal Block Connector You can force the routing of one of the two inputs to the UXGA output by remote control. To do so, connect the appropriate REMOTE input terminal block connector pins to a contact closure switch. For example, as Figure 3 illustrates, to route REMOTE IN1 to the UXGA output, connect PIN IN1 to PIN G (ground). To route REMOTE IN2 to the UXGA output, connect PIN IN2 to PIN G.
! Do not connect both the REMOTE IN 1 and the REMOTE IN 2 to PIN G simultaneously. Route input 1 to the output, by attaching PIN IN 1 to PIN G: Route input 2 to the output, by attaching PIN IN 2 to PIN G: Figure 3: REMOTE Terminal Block Connector 4.2 Selecting the Default Master Source Signal The DEFAULT INPUT switch is factory preset to IN 1 and the VP-211K detects the presence of the master source signal at the UXGA IN 1 connector.
If the VP-211K detects: No signal (perhaps no connected source, or a source is connected and powered OFF) at the UXGA IN 1 input (when IN 1 is selected as the default), the VP-211K routes the signal from the source at UXGA IN 2 to the UXGA OUT and the AUDIO OUT connectors.
