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
Go to http://www.kramerelectronics.com/support/product_downloads.asp
to check for up-to-date user manuals, application programs, and to check if
firmware upgrades are available (where appropriate).
2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer 614T, 614R away from moisture, excessive sunlight
and dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.

2.3 Recycling Kramer Products
The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC
aims to reduce the amount of WEEE sent for disposal to landfill or incineration by
requiring it to be collected and recycled. To comply with the WEEE Directive,
Kramer Electronics has made arrangements with the European Advanced
Recycling Network (EARN) and will cover any costs of treatment, recycling and
recovery of waste Kramer Electronics branded equipment on arrival at the EARN

614T, 614R - Overview
3 Overview
The 614T and 614R are a detachable optical transmitter and receiver for sending
DVI-D signals with resolutions of up to 1920x1200 at 60Hz over one multimode
fiber optic cable with SC connectors. The 614T converts the DVI-D signal to an
optical signal that it transmits to the 614R. The 614R decodes the optical signals
back to a single link DVI-D signal.
The 614T and 614R feature:
A maximum data rate of 6.75Gbps (2.25Gbps per graphic channel)
Supported resolutions of up to WUXGA, 2K or 1080p (XGA not supported)
A range of up to 500m (1640ft) (multimode)
1 SC multimode fiber optic cable connector
EDID capture that copies and stores the EDID from a display device (614T)
Standards compliance - supports DVI1.0, fully implemented by fiber-optic
communication and DDC2B by virtual DDC
Compliance with the limits for a Class A digital device, pursuant to part 15
and 2 of FCC and CE
Laser standards compliance - IEC 60825-1, FDA 21CFR1040;
Laser Class 1: Safety of laser products
No EMI/RFI for connected cables
HDTV compatibility, no HDCP compliance
Two external 5V DC power adapters (supplied)
NanoTools size

3.1 Powering the 614T and the 614R
Your 614T/614R pair comes with two 5V DC power adapters. The 614R module
must always be powered by the power adapter. The 614T can be powered either
by an external power adapter or internally by the 5V pin on the DVI card of the
computer. The 614T automatically detects if it is being powered via the external
power adapter, and if so, the internal power supply will be cut off. Use of the
external power adapter for the 614T is strongly recommended for better
performance.

614T, 614R - Using the Detachable Optical DVI System
4 Using the Detachable Optical DVI System
This section describes how to:
Capture the EDID of the display device (see Section 4.1)
Connect the One-Fiber Detachable Optical DVI Transmitter and receiver (see
Section 4.2)
Troubleshoot the 614T and 614R (see Section 4.3)
4.1 Capturing the EDID
The 614T and 614R are connected via one channel that transmits R, G, B and
clock signals. The EDID of the display device is captured by the transmitter for the
computer to read.
The factory default EDID is set to UXGA (1600x1200). 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 614T so that when the
computer connects to the 614T, it reads the virtual EDID information and identifies
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 the display device is
replaced, the new EDID must be set on the 614T transmitter.
To capture the EDID of a display device, do the following:
1. Power the display on.
2. Connect the 5V power adapter to the power socket of the 614T, and connect
the adapter to the mains electricity.
The power LED lights.
3. Push the EDID button (illustrated in Figure 1), using a thin screwdriver.
The status LED lights.

4. Connect the 614T unit directly to the display device.
The status LED flashes rapidly while reading the EDID and turns off after
about 7-8 seconds.
5. Disconnect the 614T from the display.
The new EDID information is stored.

4.2 Connecting the One-Fiber Detachable Optical DVI
System
To connect the 614T One-Fiber Detachable Optical DVI-D Transmitter with the
614R One-Fiber Detachable Optical DVI-D Receiver, as the example in Figure 2
illustrates, do the following:
1. Set the EDID of the display device (see Section 4.1).
2. Plug the 614T DVI connector directly to the DVI connector of the computer.
Do not use any intermediate cable or adapter between them.
3. Connect the 614R to the 5V DC power adapter and connect the adapter to
the mains electricity. The indication LED lights.
4. Connect the 614R DVI connector directly to the DVI connector of the display
device.
Do not use any intermediate cable or adapter between them.
5. Connect the single multimode fiber cable with SC connectors to the 614T
and 614R modules.

6. Turn ON the Power on the computer and the display device.
7. If the transmitter does not power up, connect the 5V power adapter to the
614T transmitter, and connect the adapter to the mains electricity.
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.
8. Set up the screen resolution as required.

4.3 Avoiding Pitfalls with the 614T and 614R
Note: The 614T, 614R pair does not support XGA (1024x768)
resolution.
If any of the following problems occur, we recommend:
If the display device shows only a black screen:
Check that all the AC and DC plugs and jacks used by the external power
supplies are firmly connected
Check 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

If the screen is distorted or displays noise:
Check if the graphics resolution is properly set
Go to the Display Properties of Windows and check the settings
Be sure that the resolution is set for WUXGA (1920x1200) at 60Hz, or lower
Reset the system
Disconnect and reconnect the optical DVI cables
Be sure that at all times the cables are stored and used away from
liquid or dirt.
