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 t o 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)

• Avoid interference from neighboring electrical appliances that may adversely

influence signal quality

• Position your Kramer F-121UK away from moisture, excessive sunlight and

dust

Caution: No operator serviceable parts inside the unit
Warning:

3 Overview

The F-121UK mounting box for Ackermann Cablelink Plus Modular floorboxes is a
twisted pair transmitter for computer graphics video signals up to UXGA and
unbalanced stereo audio. It converts the input signals into a twisted pair signal
that it transmits to a compatible twisted pair receiver (for example, the Kramer
TP-122N). The F-121UK includes one opening (covered by a blank panel) for a
single Kramer insert.

In particular, the F-121UK transmitter features:

• A transmission range of more than 300ft (more than 100m), and a 20kHz

audio bandwidth with an S/N ratio that exceeds 80dB on the same
transmission range

• The capability to store EDID when programmed by the Kramer FC-200 XGA

EDID Copier (the EDID of the display on the transmitter can be captured via

the FC-200)

• A resolution of up to UXGA

• The Kramer Power Connect™ feature

• A 12V DC power supply

3.1 Shielded Twisted Pair (STP) / Unshielded Twisted Pair
(UTP)

We recommend that you use Shielded Twisted Pair (STP) cable. There are
different levels of STP cable available, and we advise you to use the best quality
STP cable that you can afford. Our non-skew-free cable, Kramer BC-STP is
intended for analog signals where skewing is not an issue. For cases where there
is skewing, our UTP skew-free cable, Kramer BC-XTP, may be used. Bear in
mind, though, that we advise using STP cables where possible, since the
compliance to electromagnetic interference was tested using those cables.

Although Unshielded Twisted Pair (UTP) cable might be preferred for long range
applications, the UTP cable should be installed far away from electric cables,
motors and so on, which are prone to create electrical interference.
However, since the use of UTP cable might cause inconformity to electromagnetic
standards, Kramer does not commit to meeting the standard with UTP cable.

3.2 About the Power Connect™ Feature

The Power Connect feature applies as long as the cable can carry power. This
feature is available when using STP cable and the distance does not exceed 50m
on standard CAT 5 cable. For longer distances, heavy gauge cable should be
used (CAT 5 cable is still suitable for the video/audio transmission, but not for
feeding the power at these distances). For units which are connected via RJ-45
connectors, make sure that the shield of the STP cable is connected to the metal
casing of the connectors on both ends of the cable. For units which are connected
via terminal block connectors, the shield of the STP cable must be connected to a
ground terminal on the units at both ends (use the ground terminal of the power
supply connection if necessary).

For a CAT 5 cable exceeding a distance of 50m, separate power supplies should
be connected to the transmitter and to the receiver simultaneously.
