3 Overview
The 602T and 602R transmitter/receiver pair is an:
Advanced solution—and yet, small and lightweight—that sends DVI
signals over fiber optic cable
Exciting and versatile product that lets you transmit either using
multi-mode optical fiber to up to 1650 feet (500 meters) or, if a further
transmission distance is required, using single-mode optical fiber to up to
5000 feet (1500 meters), over two fiber optic cables with LC connectors
Indispensable asset in any digital signage application. By design, the
602T/602R uses complex technology but with an outward simplicity that
makes using it really easy
The 602T converts electrical signals to optical signals and the 602R decodes
the optical signals back to electrical signals. The 602T can read the EDID1, of
the display device, and once it is connected to the computer, it provides this
data2
In particular, the 602T/602R pair:
.
Has a transmission range of up to 1500m (5000ft.), when using two
9(8)/125m core LC single-mode fibers
Has a transmission range of up to 500m (1650ft.), when using two
62.5(50)/125m core LC multi-mode fibers
Is EMI/RFI cable free
Provides a single-link DVI-D connection3
Supports DVI1.0 and DDC2B, fully implemented by fiber-optic
communication
Supports resolutions exceeding WUXGA (1920x1200) at 60Hz vertical
refresh rate or 1.65Gbps bandwidth per graphic channel
Transmits one red, one green and one blue channel, and one clock with a
1 pixel/clock mode over the fiber optic cables, with 2 duplex LC fiber
connectors
Complies with the limits for a Class A digital device, pursuant to part 15
and 2 of FCC and CE
Does not require any special memory size, CPU speed and chipsets, when
using a computer

To achieve the best performance:
•Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise-
levels (often associated with low quality cables)
•Position your Kramer 602R and 602T away from moisture, excessive
sunlight and dust
3.1 Powering the 602T and the 602R
Your 602T/602R pair comes with two 5V DC power adapters. The 602R
must always be powered via the external power adapter. The 602T can be
powered via the external power adapter or it can derive its power via the
computer’s 5V pin on the DVI card. However, when using most laptops or a
computer with an express graphic card, an external power adapter is required.
The 602T automatically detects if it is being powered via the external power
adapter, and if so, the internal power supply will be cut off.

5 Using the Two-fiber Detachable Optical DVI System
This section describes how to:
•Capture the EDID of the display device (see Section 5.1)
•Connect the detachable optical DVI transmitter and receiver (see Section 5.2)
•Avoid pitfalls when using the 602T and 602R (see Section 5.3)
5.1 The Display Device EDID
The 602T and 602R are connected via two channels that transmit R, G, B and
clock signals. The EDID of the display device is captured onto the transmitter
for the computer to read.

5.1.1 Defining EDID
The Extended Display Identification Data (EDID
1
) is a data-structure,
provided by a display, to describe its capabilities to the DVI graphics source
(for example, the graphics card of the computer). The EDID enables the
computer to “know” what kind of monitor is connected to the output. The
EDID includes the manufacturer’s name, the product type, the phosphor or
filter type, the timing data supported by the display, the display size,
luminance data and, for digital displays only, the pixel mapping data.
5.1.2 Capturing the Virtual EDID
The factory default EDID is set to UXGA (1600x1200) at 60Hz vertical
refresh rate. If your display has this resolution, you do not need to capture the
EDID.
You can capture the EDID of the display device on the 602T so that when the
computer connects to the 602T, it will read the virtual EDID information and
identify the display device. This procedure is performed only once for the
connected display device. After storing the EDID, the system can be
connected and disconnected without having to set the EDID again. If you
decide to use a different display, then you will need to set the EDID again.
To capture the EDID of a display device, do the following:
1. Connect the power to the display.
2. Connect the 5V power adapter to the power socket of the 602T, and connect
the adapter to the mains electricity.
3. Push the EDID button (illustrated in Figure 2), using a small screwdriver.
The EDID LED blinks twice and turns off.
4. Connect the 602T unit directly to the display device (while it is powered ON).
The EDID LED blinks several times while reading the EDID. The LED turns
OFF after about eight seconds.
5. Disconnect the transmitter from the display.
The LED lights
6. Disconnect the 602T.
The EDID information is now stored and the Indication LED is on.
1 EDID is defined by a standard published by the Video Electronics Standards Association (VESA)

5.2 Connecting the Detachable Optical DVI Transmitter/Receiver
To connect the 602T Two-fiber Detachable Optical DVI Transmitter with the
602R Two-fiber Detachable Optical DVI Receiver, as the example in Figure 4
illustrates, do the following:
1. Set the EDID of the display device (see Section 5.1
2. Connect the 602R to the 5V DC power adapter and connect the adapter to the
mains electricity. The blue LED lights.

3. Connect the duplex LC fiber cables1to the 602T and 602Rmodules, one
cable at a time, as illustrated in Figure 3.
4. Plug the 602TDVI connector directly2

6. Turn ON the Power on the computer and then on the display device.
7. If the transmitter does not power up, connect the 5V power adapter1to the
602Ttransmitter, and connect the adapter to the mains electricity.

5.3 Avoiding Pitfalls using the 602T and 602R
If any of these problems occur, we recommend the following:
If the display device shows only a black screen:
Make sure that all the AC and DC plugs and jacks used by the external
power supplies are firmly connected
Be sure that the DVI ports are firmly plugged into the computer and the
display device, and be sure that the Transmitter and Receiver modules are
correctly plugged into the computer and display device, respectively
Check if the computer and display are powered ON and properly booted
Reset the system by unplugging and then replugging the Transmitter DVI
port or Receiver DVI port and then reboot the system
1 You can use the power supplied through a DVI pin from the graphic cards instead of using the power adapter. After
completing the installation, if the system does not seem to work properly, reconnect the power adapter while the system is
powered
