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.
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 Use Kramer high performance high resolution cables Use only the power cord that is supplied with this machine 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).
3 Overview The VP-81K is a high-performance switcher for computer graphics video signals, with resolutions up to and exceeding UXGA, and unbalanced stereo audio signals. The unit can switch any one of eight inputs to two identical video outputs, one balanced and one unbalanced stereo audio outputs.
3.1 DDC Support When establishing a VGA connection between a PC or laptop and a display device, a set of parameters known as EDID is exchanged between them, which is carried over the DDC channel. In some PC graphic cards and laptops, this information exchange is essential for proper VGA OUT operation. 3.2 Defining EDID The Extended Display Identification Data (EDID) is a data-structure provided by a display, to describe its capabilities to a graphics card (that is connected to the display’s source).

3.4 Using the IR Transmitter You can use the RC-IR3 IR transmitter to control the machine via the built-in IR receiver on the front panel or, instead, via an optional external IR receiver (Model: C-A35M/IRR-50). The external IR receiver can be located up to 15 meters away from the machine. This distance can be extended to up to 60 meters when used with three extension cables (Model: C-A35M/A35F-50).
4 Installing in a Rack This section provides instructions for rack mounting the unit. Before Installing in a Rack How to Rack Mount Before installing in a rack, be sure that the environment is within the recommended range: To rack-mount a machine: 1. Attach both ear brackets to the machine. To do so, remove the screws from each side of the machine (3 on each side), and replace those screws through the ear brackets.
5 Connecting the VP-81K i Always switch off the power to each device before connecting it to your VP-81K. After connecting your VP-81K, connect its power and then switch on the power to each device. To connect the VP-81K, as illustrated in the example in Figure 3, do the following: 1. Connect up to eight UXGA computer graphics sources to the INPUT 15-pin HD connectors (from 1 to 8). You do not have to connect all the inputs. 2.

11.3 Kramer Protocol 2000 This RS-232/RS-485/Ethernet communication protocol (Version 0.5) uses four bytes of information as defined below. For RS-232, a null-modem connection between the machine and controller is used. The default data rate is 9600 baud, with no parity, 8 data bits and 1 stop bit.
Note: All values in the table are decimal, unless otherwise stated.
NOTE 1 - When the master switcher is reset, (e.g. when it is turned on), the reset code is sent to the PC. If this code is sent to the switchers, it will reset according to the present power-down settings. NOTE 2 - These are bi-directional definitions. That is, if the switcher receives the code, it will perform the instruction; and if the instruction is performed (due to a keystroke operation on the front panel), then these codes are sent.
NOTE 24 – Further information needed in instructions 21, 22, 25 and 26 is sent using instruction 42 – which is sent prior to the instruction. For example, to request the audio gain value of right input # 9, send hex codes 2A 84 80 81 and then send HEX codes 19 89 81 81. To set MIX mode, send hex codes 2A 81 84 81 and then send HEX codes 16 NOTE 25 – For units which detect the validity of the video inputs, Instruction 16 will be sent whenever the unit detects a change in the state of an input (in real-time).
