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 631T/R 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.

631T/R - Overview
3 Overview
The Kramer DigiTOOLS® 631T HDMI Optical Transmitter and the 631R HDMI
Optical Receiver are an optical transmitter and receiver pair for transmitting HDMI
signals up to 1600x1200 at 60Hz. The 631T converts an HDMI signal into an
optical signal and the 631R converts the optical signal back to HDMI.
The 631T/631R features:
A maximum data rate of 6.75Gbps (2.25Gbps per graphic channel)
HDTV compatibility and HDCP compliance
A system range of up to 100m (320ft)
The Power Connect™ System - Only one unit in a system, the transmitter or
the receiver, needs to be connected to a power source when the devices are
within 50m (150ft) of each other
Use of UTP (unshielded twisted pair) or STP (shielded twisted pair) cables
such as CAT 5 and fiber optic with 4 simplex or 2 duplex LC fiber connectors
A compact DigiTOOLS® structure - 3 units can be rack mounted side-by-
side in a 1U rack space with the optional RK-3T rack adapter
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 60m (197ft) of each other. The Power Connect™ feature
applies as long as the cable can carry power and the distance does not exceed
60m on standard TP cable. (Heavier gauge cable may be used to extend the
Power Connect™ range).

631T/R - Using the 631T/631R HDMI Optical Transmitter/Receiver
4 Using the 631T/631R HDMI Optical
Transmitter/Receiver
Always switch off the power to each device before connecting it to your
631T/R. After connecting your 631T/R, connect its power and then
switch on the power to each device.
You can use the 631T and 631R to configure an HDMI optical transmitter and
receiver system. This section describes how to:
Connect the 631T/631R transmitter and receiver system (see Section 4.1)
Operate the 631T/631R transmitter and receiver system (see Section 4.2)
Wire the DDC (CAT 5) RJ-45 connectors (see Section 4.3)
Avoid pitfalls (see Section 4.4)
4.1 Connecting the 631T/631R HDMI Optical
Transmitter/Receiver
To connect the 631T with the 631R, as the example in Figure 3 illustrates, do the
following:
1. On the 631T, connect the HDMI source (for example, a set top box) to the
HDMI IN connector, using the Kramer HDMI copper cable.
Note: Do not look directly into the LC receptacles of the 631T, while powered on,
although this product is regulated strictly enough to operate under the Laser Class 1,
classified by CDRH/FDA for eye safety.
2. On the 631R, connect the HDMI OUT connector to the HDMI acceptor (for
example, a display), using Kramer HDMI copper cable.
3. Remove the module dust covers and connect each duplex LC fiber cable
one-by-one to each of the four LC receptacles of the 631T and 631R. The 4
LC patch cord fiber bundled cable lets you transmit 4 channels (R, G, B, and CL
(CLOCK)) of graphic data and multi-channel audio data over it.
Note: Carefully recheck the polarities and ensure that the duplex connectors are fully
engaged.
4. Connect the DDC RJ-45C connector on the 631T to the DDC RJ-45C
connector on the 631R, via UTP cabling, see Section 4.3.

5. Connect the 12V DC, 2.1Apower adapter to the power socket of either the
631T or 631R, and connect the adapter to the mains electricity.
The signal from the HDMI source is transmitted via CAT5 and fiber optic
cables, decoded and converted at the HDMI OUT connector to the HDMI
acceptor.
The power connect feature lets you connect just one power adapter to either the
transmitter or receiver. Alternatively, connect the separate power supplies to the
transmitter and to the receiver simultaneously

4.2 Operating the 631T/631R HDMI Optical
Transmitter/Receiver
To operate the 631T/631R HDMI Optical Transmitter/Receiver system:
Turn ON the power on the set-top box and the display
Note: Avoid “hot plugging” the 631T or 631R. This is not a recommended practice with
live digital voltages (but it can be done)
