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 video, audio, presentation, and broadcasting professionals 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 • 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).
2.2 Safety Instructions ! 2.
3 Overview The high performance Kramer 622T and 622R have a transmission range of more than 300 ft. (more than 100 meters) of dual link high-resolution digital graphic data over fiber optic cables and EDID/HDCP parameters over DDC (UTP) cabling. Using DDC (Digital Display Channel), the display can inform the video card about its properties, such as the maximum resolution and the color depth.
3.1 About the Power Connect™ Feature The Power Connect™ feature here means that only one unit in a system, the transmitter or receiver, needs to be connected to a power source when the devices are within 90m (270ft) of each other. The Power Connect™ feature applies as long as the cable can carry power and the distance does not exceed 90m on standard TP cable.
4 Defining the 622T, 622R Dual Link DVI Optical Transmitter/Receiver This section defines the dual link DVI Optical Transmitter/Receiver: 4.1 • 622T Dual Link DVI Optical Transmitter (see Section 4.1) • 622R Dual Link DVI Optical Receiver (see Section 4.

5 Connecting and Operating the 622T, 622R i Always switch off the power to each device before connecting it to your 622T, 622R. After connecting your 622T, 622R, connect its power and then switch on the power to each device. We recommend testing your system configuration by first connecting the entire system (as illustrated in Figure 3), using short copper cables instead of optical fiber cables.
! Do not look directly into the LC receptacles of the 622T, while powered on, although this product is regulated strictly enough to operate under the Laser Class 1, classified by CDRH/FDA for eye safety. 5. Connect the DDC RJ-45C connector on the 622T to the DDC RJ-45C connector on the 622R, via UTP cabling (see Section 5.3). 6. Connect the 12V 2.1A DC power adapter to the power socket of either the 622T or the 622R and connect the adapter to the mains electricity (not shown).
5.2 Operating the 622T/622R Dual Link DVI Optical Transmitter/Receiver To properly operate the 622T/622R system: • Make sure you have a media receiver or a graphic controller card with a dual link DVI connector on your PC/Mac or SUN system. • Make sure that your graphic card supports the maximum resolution of the display you are about to connect • Avoid “hot plugging” the 622T or 622R. This is not a recommended practice with live digital voltages 5.
