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.
connected to an amplifier (leading to the receiver or monitor) may present a capacitive and/or an inductive load to the amplifier. This is the main cause for instability. The non-ideal behavior of a load or cable may severely degrade the performance of the amplifier - it’s bandwidth, linearity, and stability - and in general it’s ability to faithfully reproduce the signal. The cables affect image resolution.

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. So if the section doesn’t apply to you, you don’t have to spend your time reading it. UNPACKING AND CONTENTS The items contained in your Kramer switcher package are listed below.
VP-211 - (2x1 Automatic VGA/Audio Switcher) can be serially inserted between the VGA/audio switcher and the acceptors for VGA/audio distribution. It is a full bandwidth switcher designed for computer and presentation applications. The VP-211 automatically detects the presence of a VGA/XGA signal on input no. 1 and routes it to the output. If the signal disappears, the machine switches to input no. 2 and routes it to the output. When the signal on input no. 1 re-appears, the VP-211 reroutes input no.
VGA/XGA/AUDIO SWITCHERS This section describes all the controls and connections of your switcher. Understanding them helps you realize the full power of your switcher. Getting to Know Your VP-31 Switcher The KRAMER VP-31 is a full bandwidth, 3x1 VGA/XGA Switcher designed for computer and workstation applications. The VP-31 switches one of three VGA/Super-VGA/XGA graphics card outputs to one monitor or vice versa, with no discernible signal degradation.
Getting to Know Your VP-32xl Switcher The KRAMER VP-32xl is a full bandwidth, 3x1 VGA/Audio Stereo Switcher designed for computer, workstation and presentation applications. The VP-32xl switches one of three sets of VGA/Super-VGA/XGA graphics/Audio stereo sources into up to two monitors or wide screen projectors, with no discernible signal degradation. Output of the VP-32xl is divided into two, thus it functions as a VGA/Audio DA as well.
Getting to Know Your VP-61RS Switcher The KRAMER VP-61RS is a full bandwidth, 6x1 VGA/XGA Switcher designed for computer and workstation applications. The VP-61RS switches one of six VGA/Super-VGA/XGA graphics card outputs to one monitor or vice versa, with no discernible signal degradation. The VP-61RS also has RS-232 control. Input and output are directly coupled and conform to the highest standards.
INSTALLATION Rack Mounting The VP-61RS switcher included in this manual may be rackmounted in a standard 19” (1U) EIA rack assembly, and includes rack “ears” at the ends of the front. The VP-31 and the VP-32xl can be installed in a rack, using a special rack adapter (contact your KRAMER dealer). These machines do not require any specific spacing above or below the unit for ventilation.
Figure 4: VP-32xl Remote Connector Location and Pinout Controlling the VP-61RS The VP-61RS switcher can be controlled by the following methods: 1) By touch buttons on the front panel (see section 9.2 "Selecting an Input on the Switchers"). 2) By any RS-232 controller such as a PC or the VS-2000 (for more information, refer to Section 9.4.1: The VS-2000 System") which is programmed according to the protocol of the switcher (see Section 13: “Protocol Used for VP-61RS Communication"). The VS-2000 System 9.
Figure 5: Typical VS-2000 System Setup 9.4.2 DIP Switches The VP-61RS selects one of 6 VGA/Super-VGA/XGA standard signals. As said before there are two options for operating the switcher, both are available without removing the switcher cover. It can be operated by touching one of the front panel switches. It can be operated by a remote PC via the RS-232 connectors on its rear panel.

Figure 6: Typical VGA/XGA Switching CONNECTING TO A PC (VP-61RS only) To connect directly to a PC without using the KRAMER Null-Modem Adapter, make connections as in Figure 7. To use the KRAMER Adapter instead (recommended), plug one end into the PC' s serial port, then connect from the other end to the switcher using a 9-pin flat-cable. When multi-machines are to be connected together, make the connections as in Figure 8, or extend pins "5" and "9" only.
PC Control Software 10.1.1 Installation To install the Control Software perform the following steps: 1) Insert the program diskette #1 into the floppy drive of your PC. 2) From within Windows95®, or higher run the Setup.exe file on the first diskette and follow the instructions. The K-switch software and icon are automatically installed in a specific destination folder on the hard disk. 3) Once the installation is completed, the K-Switch program may be run. 10.1.
Input Description Labels Used by the operator to name a selected input. The input name is saved when the Save button is clicked. Setup Description Labels Used by the operator to name each setup. The setup names correspond to the Setup window numbers and are stored when the Save button is clicked. 10.1.
7) 8) If properly connected and with the right COM port selected, you can identify your switcher and view an image representing its control panel on the PC monitor (with the current configuration). If the COM or switcher are not properly selected, "Communication Error" message appears. 9) To exit the program, click the "Exit" button. You are prompted for confirmation. NOTE When clicking "Exit", the program automatically stores the active port number and your switcher ID.
TROUBLESHOOTING NOTES 1. Please note that if the output signal is disturbed or interrupted by very strong external electromagnetic interference, it should return and stabilize when such interference ends. If not, turn the power switch off and then on again to reset the machine. 2. If the recommended actions still do not result in satisfactory operation, please consult your KRAMER Dealer. Power and Indicators Problem Remedy No Power 1. 2. 1. 2. 1. 2. 3. 4. 5.
Figure 9: VP-32xl Fuse Location Audio Signal (VP-32xl only) Problem Remedy No audio at the output device, regardless of input selected 1. 2. Audio level is too low 1. 2. Confirm that your sources and output device are powered on and connected properly. Audio signals connected to the input of your switcher should be properly wired to the output of your source. Audio signals connected to the output of your switcher should be properly wired to the input of your line amplifier or recorder.
Problem Remedy Noise bars are "rolling" up or down in the output video image Hum bars (ground loop) are caused by a difference in the ground potential of any two or more devices connected to your signal path. This difference is compensated by passing that voltage difference through any available interconnection, including your video cables.
PROTOCOL USED FOR THE VP-61RS COMMUNICATION The protocol used for communication between the PC and the VP-61RS is defined below. The rate of data is 9600 baud with no parity, 8 data bits and one stop bit. To work at 1200 baud, DIP switch number 5 should be set to "OFF".
