ADDENDUM: Included with user manuals for machines with a CAT5 connector
This addendum describes the Power Connect feature used with Kramer
machines, and the choice between STP and UTP CAT5 cables.
Power Connect Feature
1
The Power Connect feature lets you power a transmitter / receiver system by
connecting just one power adapter to either the transmitter or the receiver. The
other unit is fed over the same CAT5 cable.
The Power Connect feature applies as long as the CAT5 cable is heavy gauge
cable (that is, it can carry power). The distance does not exceed 50 meters on
standard cable.
For a distance of 100 meters, separate power supplies must be connected to the
transmitter and to the receiver simultaneously, unless using heavy gauge CAT5
cable.
Shielded Twisted Pair (STP) / Unshielded Twisted Pair (UTP)
The decision whether to use shielded twisted pair (STP) cable or unshielded
twisted pair (UTP) cable depends on the nature of the application.
It is recommended that in applications with high interference, shielded twisted
pair (STP) cable will give better results. However, the shield itself does create a
capacitance that degrades the frequency response of the machines. For shorter
distances, of 50m or so, shielded twisted pair (STP) cable is preferred because it
provides protection from interference (degradation is non-apparent).
For a long range application, unshielded twisted pair (UTP) cable is preferred.
However, the unshielded twisted pair (UTP) cable should be installed far away
from electric cables, motors etc., which are prone to create electrical interference.
1 This section of the addendum is only relevant to machines that support this feature (for example, the TP-104; not the
TP-100)

Optical Receiver.
3.1 About HDMI
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital
2
audio/video interface, widely supported in the entertainment and home
cinema industry. It delivers the highest image and sound quality.
In particular, HDMI:
 Provides a simple
3
interface between any audio/video source, such as a
set-top box, DVD player, or A/V receiver and an audio and/or video monitor,
such as a digital television (DTV), over a single lengthy
4
cable
 Supports standard, enhanced, high-definition video, and multi-channel
digital audio
5
on a single cable
 Transmits all ATSC HDTV standards and supports 8-channel digital
audio, with bandwidth to spare to accommodate future enhancements and
requirements
 Benefits consumers by providing superior, uncompressed digital video
and audio quality via a single cable
6
, and user-friendly connector
 Is backward-compatible with DVI (Digital Visual Interface)
 Supports two-way communication between the video source (such as a
DVD player) and the DTV, enabling new functionality such as automatic
configuration and one-button play
1 The complete list of Kramer cables is on our Web site at http://www.kramerelectronics.com
2 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-
to-analog conversions
3 With video and multi-channel audio combined into a single cable, the cost, complexity, and confusion of multiple cables
currently used in A/V systems is reduced
4 HDMI technology has been designed to use standard copper cable construction at up to 15m
5 HDMI supports multiple audio formats, from standard stereo to multi-channel surround-sound. HDMI has the capacity to
support Dolby 5.1 audio and high-resolution audio formats
6 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a
simple, cost-effective manner

Overview
3
HDMI has the capacity to support:
 Existing high-definition video formats (720p, 1080i, and 1080p/60), as
well as standard definition formats such as NTSC or PAL
3.2 Recommendations for Best Performance
When setting up the 631T / 631R, be aware that:
 The Media Receiver or graphic controller card must have an HDMI port
that matches the maximum graphic resolution feature of the display to be
connected. When using a computer, there are no special hardware
requirements concerning memory size, CPU speed or chipsets
 There are no special software requirements
1
 We recommend that you test the entire platform with its application using
a short length copper cable, before you install the optical link
 The power connect feature lets you power the 631T /631R system by
connecting just one power adapter to either the 631T or the 631R. The other unit
is fed via the CAT5 cable
 CAUTION: Never look directly into the LC receptacles of the 631T /
631R, while it is powered on
2
To achieve the best performance
3
:
 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)
 Avoid interference from neighboring electrical appliances and position
your Kramer DigiTOOLS® away from moisture, excessive sunlight and dust
 Be sure to keep the optical cable’s connectors clean. Close them when not
in use, to protect them against exposure to dirt and dust
1 However, the HDMI graphic controller and display peripheral should be operational with the operating system and the
application
2 Even though this product is regulated strictly enough to operate under the Laser Class 1, classified by the CDRH/FDA for

5 Using the 631T/631R HDMI Optical Transmitter/Receiver
You can use the 631T and 631R to configure an HDMI optical transmitter and
receiver system. In particular, this section describes how to:
 Connect the 631T/631R transmitter and receiver system (see section 5.1)
 Operate the 631T/631R transmitter and receiver system (see section 5.2)
 Wire the DDC
1
(CAT5) RJ-45 connectors (see section 5.3)
 Avoid pitfalls (see section 5.4)
5.1 Connecting the 631T/631R HDMI Optical Transmitter/Receiver
The example in Figure 7 shows how to configure an HDMI optical transmitter
and receiver system from the perspective of connecting the source and
acceptor. The example in Figure 8 shows how to configure an HDMI optical
transmitter and receiver system from the perspective of connecting the OPTIC
and DDC cables.
To connect the 631T with the 631R, as the examples in Figure 7 and Figure 8
illustrate, do the following:
1. On the 631T, connect the HDMI source (for example, a set top box
2
) to the
HDMI IN connector, using the Kramer HDMI copper cable.
Note: Ensure that the system is not powered up when connecting the HDMI
source.
2. On the 631R, connect the HDMI OUT connector to the HDMI acceptor
(for example, a display), 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.
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 5.3.

5. Connect the 12V 2.1A DC power adapter to the power socket of either
1
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.

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)

5.4 Avoiding Pitfalls using the 631T / 631R
Be aware of the following:
 If the display device shows only a black screen – be sure that the AC
plugs and the DC jacks used by external power supplies are firmly connected;
that the power bars are live; and that the 631T / 631R are connected correctly
to the media receiver or computer and display, respectively. Also, check if the
media receiver or computer and display are powered on and properly booted.
In addition, reboot the system after reconnecting the optical system cable
 If the screen is distorted or displays noise - check if the graphics
resolution is properly set. Go to the Display Properties of Windows and click
on the Settings. Be sure that the resolution is set at equal to or less than UXGA
(1600x1200) at 60Hz refresh ratio. In addition, reset the system. Power down,
disconnect and reconnect the optical system cable and/or the DC power
adapter(s), and power up
