2 F-121UK - 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)

•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: Use only the Kramer Electronics input power wall

adapter that is provided with the unit

Warning: Disconnect the power and unplug the unit from the wall

before installing

F-121UK - Overview 3

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.

F-121UK - Overview 5

3.3 DDC Support

When establishing a VGA connection between a PC or laptop and a display device, a

set of parameters known as EDID is exchanged between them, which is carried over

the DDC channel. In some PC graphic cards and laptops, this information exchange is

essential for proper VGA OUT operation.

3.4 Defining EDID

The Extended Display Identification Data (EDID) is a data-structure provided by a

display, to describe its capabilities to a graphics card (that is connected to the

display’s source). The EDID enables the F-121UK to “know” what kind of monitor

is connected to the output. The EDID includes the manufacturer’s name, the

product type, the timing data supported by the display, the display size, luminance

data and (for digital displays only) the pixel mapping data.

EDID is defined by a standard published by the Video Electronics Standards

Association (VESA).

5 Installing the F-121UK

To install the F-121UK you have to install the inserts and the transmitter which is

connected via TP to a receiver.

To install the F-121UK, do the following:

•Install the Kramer inserts (see Section 5.1

•Connect the cables to the rear side (see

)

Section 5.2

•Install the F-121UK inside the Ackermann floor box (see

)

Section 5.3

•Connect the front panel ports (see

)

Section 5.4

•Connect the twisted pair cable to the receiver (for example, the Kramer

TP-122N)

)

5.1 Installing a Kramer Insert

To install a Kramer insert, do the following:

1. Unscrew the two screws holding the blank insert and remove it.

2. Place and align the required wall plate insert item over the opening.

3. Insert the two screws to fix the insert in place, and tighten them.

5.2 Connecting the Cables to the Rear Side of the F-121UK

To connect the rear side cables, do the following:

1. Run the cables through the Ackermann underfloor cable opening.

2. Connect the cables to the rear side of the inserts.

3. Connect the cables to the rear side of the F-121UK transmitter, that is,

attach the:

Terminal block line output of the F-121UK to the pre-installed STP/UTP

wiring that connects to the TP receiver (for example, the Kramer

TP-122Nwith a range of more than 300ft (>100m)), see Section 5.5

8 F-121UK - Installing the F-121UK

12V DC power supply to the power terminal blocks (connect the wire

labeled “+” to the +12V pin, and the wire labeled “–” to the GND pin)

taking care that the polarity is correct (see Figure 4)

5.3 Installing the F-121UK inside the Ackermann Floor Box

To install the F-121UK inside the Ackermann floor box:

1. Remove the Ackermann box from the Ackermann floor box.

2. Unscrew the three screws holding the box together: one on the lower side of

the box and the third one on top.

3. Separate the two red plastic parts.

4. Unscrew the two screws on each side of the brackets on the F-121UK (four

in total) and put the screws to one side (you will need them later; see step

7).
