1 INTRODUCTION Congratulations on your purchase of this Kramer switcher. Since 1981, Kramer has been dedicated to the development and manufacture of high quality video/audio equipment. The Kramer line has become an integral part of many of the best production and presentation facilities around the world. In recent years, Kramer has redesigned and upgraded most of the line, making the best even better.
simultaneously displayed colors on the screen and is measured in bits. 24 and 3236 bits of color depth represent millions to billions of color shades available on the screen at any given moment. (It should be born in mind, though, that the human eye can resolve only a few thousands colors!) The more detailed the image (higher resolution) and the higher the color depth the more real the image will look. The highest resolution of standard VGA was 640x480 pixels with 4 bits of color (16 colors).
cable is replaced by five individual coax cables, which are bulky and cumbersome for use. Even then, the distance is limited to several tens of meters. The imperfect behavior of a cable may create other problems resulting from its failure to accurately match the system’s required impedance. The result of this, especially at high frequencies, is “shadows” or “ghosts” on the image, resulting from standing waves and electronic reflections running back and forth between transmitter and receiver.
2 HOW DO I GET STARTED? The fastest way to get started is to take your time and do everything right the first time. Taking 15 minutes to read the manual may save you a few hours later. You don’t even have to read the whole manual. If a section doesn’t apply to you, you don’t have to spend your time reading it. 3 UNPACKING AND CONTENTS The items contained in your Kramer switcher package are listed below. Please save the original box and packaging materials for possible future shipment.
bandwidth of 517MHz ensures that the VP-211 remains transparent even in the most critical applications. The VP-211 is part of the Kramer TOOLS family of compact, high quality and cost effective solutions for a variety of applications. VP-22 - (VGA / XGA Line Amplifier & Processor) can be serially inserted between the VGA switcher and the acceptors for signal processing. It is a full bandwidth machine designed for computer and workstation applications where remote monitoring is needed.
4.1 Getting to Know Your VP-61xl Switcher The Kramer VP-61xl is a 6x1 switcher for VGA/XGA and Balanced Stereo Audio signals. It is designed to route one of up to six inputs to one output using 15pin HD female connectors for the VGA/XGA signals, and detachable terminal block connectors for audio. Bandwidth exceeding 400MHz ensures transparent VGA/XGA performance. The inputs and output are directly coupled, and conform to the highest standards.
5 INSTALLATION 5.1 Rack Mounting The VP-61xl switcher may be rackmounted in a standard 19” (1U) EIA rack assembly, and includes rack “ears” at the ends of the front panel. The machine does not require any specific spacing above or below the unit for ventilation. To mount the switcher, simply place the rack ears against the rails of your rack, and insert standard screws through each of the four corner holes in the front panel.
8.3 Controlling the VP-61xl The VP-61xl switcher can be controlled by the following methods: 1. By touch buttons on the front panel. 2. By any RS-232 controller such as a PC. 8.3.1 DIP Switches The VP-61xl selects one of 6 VGA/XGA/Audio sources. The DIP switch (see Table 2) on the rear panel is used when the switcher is operated via the RS-232 connector or when it is interconnected with other switchers.
Note: The Slave "Reply" settings are all ON or all OFF, depending on the requirements of the system. The Master "Reply" setting is always ON. 9 CONNECTING TO A PC To connect directly to a PC use the KRAMER Null-Modem Adapter (recommended) plug one end into the PC' s serial port, then connect a 9-pin flatcable from the other end to the switcher.
9.1 PC Control Software If needed, install the PC software which is provided either on diskettes or on a CD and follow the instructions.

The RS-232 communication protocol may also be found on the diskettes or CD provided or on the website. 10 SPECIFICATIONS 6 Analog Red, Green, Blue signals - 0.7 Vpp/75 , H & V syncs, TTL level on HD15F connectors.
11.1 Power and Indicators Problem Remedy No Power 11.2 1. Confirm that power connections are secured at the machine and at the receptacle. Make sure the receptacle is active, outputting the proper voltage. 2. If still there is no power, remove power cord from AC outlet and then using a flat head screwdriver, remove the fuse holder located directly below the power connector on your switcher. 3. Confirm that the fuse is good by looking for the wire connected between the ends of the fuse.
