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 disp

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). Before using the external IR receiver, be sure to arrange for your Kramer dealer to inse

4 Installing in a Rack This section provides instructions for rack mounting the unit. Before Installing in a Rack How to Rack Mount To rack-mount a machine: Before installing in a rack, be sure that the environment is within the recommended range: 1. Attach both ear brackets to the machine. To do so, remove the OPERATING TEMPERATURE: 0º to +55ºC (32º to 131ºF) screws from each side of the STORAGE TEMPERATURE: -45º to +72ºC (-49º to 162ºF) machine (3 on each side), and HUMIDITY: 10% to

5 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 i 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. Connect the unbalanced audio sources to up to eight INP

5.2 Controlling via RS-232 You can connect to the unit via a crossed RS-232 connection, using for example, a PC. A crossed cable or null-modem is required as shown in method A and B respectively. If a shielded cable is used, connect the shield to pin 5. Method A (Figure 6)—Connect the RS-232 9-pin D-sub port on the unit via a crossed cable (only pin 2 to pin 3, pin 3 to pin 2, and pin 5 to pin 5 need be connected) to the RS-232 9-pin D-sub port on the PC. Note: There is no need to conne
