2 616T, 616R - Getting Started
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
•Use Kramer high-performance, high-resolution cables
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).
2.1 Achieving the Best Performance
To achieve the best performance:
•Use only good quality connection 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
•Position your Kramer 616T, 616R away from moisture, excessive sunlight
and dust

616T, 616R - Overview 3
3 Overview
The 616T and 616R are a small and lightweight fiber optic transmitter and receiver
pair that transmit uncompressed resolutions up to WQXGA (2560x1600 @60Hz)
or WQUXGA (3840x2400 @33Hz vertical refresh rate) over dual link DVI to a
range of up to 500 meters (1640 feet) over duplex multimode fiber optic cable with
two LC connectors. The 616T converts dual link DVI signals to optical signals that
it transmits to the 616R. The 616R decodes the optical signals back to a dual link
DVI signal.
The 616T and 616R feature:
•A maximum data rate of 13.5Gbps (2.25Gbps per graphic channel)
•Supported resolutions – HDTV: 480p, 720p, 1080p;
Vesa: VGA to WQUXGA @33Hz (XGA not supported)
•A range of up to 500m (1640ft) (multimode)
•Duplex multimode fiber optic cable with two LC connectors (Kramer
C-2LC/2LC series)
•EDID capture that copies and stores the EDID from a display device (616T)
•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
•No EMI/RFI from the interconnecting cable
•HDTV compatibility, no HDCP compliance
•Two external 5V DC power adapters (supplied)
•NanoTools size

3.1 Powering the 616T and the 616R
Your 616T/616R pair comes with two 5V DC power adapters. The 616R module
must always be powered by the power adapter. The 616T can be powered either
by an external power adapter or internally from the 5V pin on the DVI card of the
computer. The 616T automatically detects if it is being powered via the external
power adapter, and if so, the internal power supply is cut off. Use of the external
power adapter for the 616T is strongly recommended for better performance.

4 Using the Dual-Link Detachable Optical DVI
System
This section describes how to:
•Capture the EDID of the display device (see Section 4.1)
•Connect the detachable optical DVI transmitter and receiver (see Section 4.2)
•Avoid pitfalls when using the 616T and 616R (see Section 4.3)
4.1 7BCapturing the EDID
The 616T and 616R are connected via one dual link channel. The EDID of the
display device is captured by the transmitter for the computer to read.
The factory default EDID is set to WQXGA (2560x1600). 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 616T so that when the
computer connects to the 616T, 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 616T 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 616T, and connect
the adapter to the mains electricity.
3. Push the EDID button (illustrated in Figure 1), using a thin screwdriver.
The status LED lights.
4. Connect the 616T 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 616T from the display.
The new EDID information is stored.

4.2 Connecting the Dual-Link Detachable Optical DVI
System
To connect the 616T Dual-Link Detachable Optical DVI Transmitter with the 616R
Dual-Link Detachable Optical DVI Receiver, as the example in Figure 3 illustrates,
do the following:
1. Capture the EDID of the display device (see Section 4.1).
2. Connect the 616R to the 5V DC power adapter and connect the adapter to
the mains electricity. The LED lights.
3. Connect the duplex LC fiber cable to the 616T and 616R modules, one
connector at a time, as illustrated in Figure 2.
4. Plug the 616T DVI connector directly to the DVI connector of the computer.
Do not use any intermediate cable or adapter between them, and connect cables 1 and
2 as indicated in Figure 2.
5. Connect the 616R DVI connector directly to the DVI connector of the display
device.

6. Turn on the computer power and then turn on the display device power.
7. If the transmitter does not power up, connect the 5V power adapter to the
616T 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.

4.3 Avoiding Pitfalls During Operation
If any of these problems occur, we recommend the following:
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 Display Properties of Windows and check the settings
•Be sure that the resolution is set for WQXGA (2560 x 1600) at 60Hz, or
WQUXGA (3840x2400 @33Hz vertical refresh rate) (not to the unsupported
XGA resolution)
•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.
