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. In recent years, we have redesigned and upgraded...

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.
(that is connected to the display’s source). The EDID enables the VP-81K to “know” what kind of monitor is connected to the output. The EDID includes the manufacturer’s name, the product type, the timing data supported by the display, the display size, luminance data and (for digital displays only) the pixel mapping data.

This distance can be extended to up to 60 meters when used with three extension cables (Model: C-A35M/A35F-50). Before using the external IR receiver, be sure to arrange for your Kramer dealer to insert the internal IR connection cable (P/N: 505-70434010-S) with the 3.5mm connector that fits into the REMOTE IR opening on the rear panel.
Pay particular If you are using a Kramer rack attention to situations where electricity is adapter kit (for a machine that is supplied indirectly (when the power cord is not not 19"), see the Rack Adapters...
Connecting the VP-81K 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...

Connecting a PC or Controller to the RS-485 Port You can operate the VP-81K via the RS-485 port from a distance of up to 1200m (3900ft) using any device equipped with an RS-485 port (for example, a PC). For successful communication, you must set the RS-485 machine number and bus termination.

Select Use the following IP address, and fill in the details as shown in Figure 7. Click OK. Figure 9: Internet Protocol (TCP/IP) Properties Window VP-81K - Connecting the VP-81K...
5.4.2 Connecting via a Straight-Through Cable You can connect the Ethernet of the VP-81K to the Ethernet port on a network hub or network router, via a straight-through cable with RJ-45 connectors. 5.4.3 Configuring the Ethernet Port To configure the Ethernet port, download the P3K Wizard Ethernet configuration software.
4. If required, make changes and click Set. If not, click Close. 5.4.4 Controlling via the Embedded Web Pages The embedded Web page can be used to remotely operate the VP-81K via the Ethernet. Before you use the embedded Web pages to control the VP-81K via the Ethernet, check that the Java™...
To control the VP-81K via the embedded Web page, make sure that it is connected to the Ethernet port of your computer and do the following: 1. Open your Internet browser. 2. Type the unit’s IP number in the Address bar of your browser: The default IP number is 192.168.1.39, and may be changed by the system integrator.
A window appears announcing that the configuration has been successfully changed. 5. Click OK. 6. If the IP number had been changed, close the browser and reload the Web page. Figure 13: CONFIGURATIONS Embedded Web Page VP-81K - Connecting the VP-81K...

To cascade up to eight individual VP-81K units via RS-485, do the following: 1. Connect the computer graphics sources and acceptors, as described in Section 2. Connect the RS-232 port to the first VP-81K unit to the PC using the null- modem adapter provided with the machine (recommended), as Section 5.2 describes.
(refer to the RC-IR3 User Manual) or the infrared remote extension cable transmitter Powering up VP-81K unit, recalls the previous settings (that is, the state of the unit when it was powered down) from the non-volatile memory. Using the Front Panel Input Selector Buttons The following table describes the INPUT SELECTOR button illumination definitions.
Other switching operations are performed manually. Using the Audio-Follow-Video/Breakaway Modes By default, the VP-81K switches in true audio-follow-video mode in which all operations relate to both the video and audio. Both the VIDEO and the AUDIO buttons illuminate in this mode.
You can increase/decrease the output (from -36dB to 6dB) using the AUDIO GAIN + and - buttons. Also you can set the audio gain for each input individually using IR remote control or RS-232/Ethernet protocol commands. VP-81K - Operating Your VP-81K 8x1 UXGA/Audio Switcher...
