Overview

3 Overview
The F-021 XGA / Audio Line Amplifier Mounting Box for Ackermann floor
boxes is an XGA / Audio line amplifier for computer graphics video signals
up to UXGA and balanced stereo audio. It includes two adjacent openings
for Kramer inserts: two single Kramer inserts, or one dual Kramer insert.
The F-021 features:
•A resolution of up to UXGA
•A built-in audio amplifier
•An SDA (Serial Data) and SCL (Serial Clock) terminal block connector
to pass the EDID information via pins 12 and 15 respectively, on the
15-pin HD connector
•EQ. control for the XGA output
•Left and right audio level trimmers to adjust the output audio level
•A 12V DC power supply
3.1 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.
3.2 Defining EDID
The Extended Display Identification Data (EDID1
) 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-021 to “know” what kind of
monitor is connected to the output. The EDID includes the manufacturer’s
name, product type, timing data supported by the display, display size,
luminance data and (for digital displays only) the pixel mapping data.
1 Defined by a standard published by the Video Electronics Standards Association (VESA)

3.3 Achieving the Best Performance
To achieve the best performance:
•Use only good quality connection cables1
•Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer F-021
away from moisture, excessive sunlight and dust
to avoid interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low-quality cables)

Box
To install the F-021 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-021 inside the Ackermann floor box (see section 5.3)
•Connect the front panel ports (see section 5.4)
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 Rear Side of the F-021
To connect the rear side cables, do the following:
1. Run the cables through the Ackermann under floor cable opening.
2. Connect the cables to the rear side of the inserts.
3. Connect the cables1to the rear side of the F-021 (see section 5.2.1), that
is, attach the:
RGBHV terminal block output to the RGBHV acceptor (for
example, a display)
SDA and SCL terminal block connector to pins 12 and 15 of the XGA
output connector
Left and right balanced stereo audio terminal block connectors to
the audio acceptor (for example, active speakers)
4. Connect the 12V DC power supply to the power terminal block
(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 2).
1 We recommend that you use Kramer C-GM/XL cable, which has a molded male 15-pin HD connector installed on one end,
and the corresponding RGBHV coaxes exposed, pre-stripped and tinned at the other end, as well as two additional wires to
connect pins 12 and 15 for EDID support for details, see our Web site at http://www kramerelectronics com

5.2.1 Wiring the 18-pin Terminal Block Output Connector
The 18-pin terminal block is an easy plug-in connector for attaching the
outputs. Follow the colors of the color-coded sticker on these terminals for
proper connection of the UTP cable. Figure 2defines the pinout for the
terminal block.

Note:
•Use the connector clips only when removing wires, not when inserting
them
•Each wire should protrude 9mm (0.35") from the plastic insulation so
that it can be easily connected. Be sure to fully insert each wire to
prevent them from crossing

5.3 Installing the F-021 inside the Ackermann Floor Box
To install the F-021 inside the Ackermann floor box, as illustrated in
Figure 3, perform the following steps:
Step 1. Loosen the two slide screws (without removing them) so that the
adjustable mounting slide will move freely.
Step 2. Fit the F-021 mounting box into its designated place inside the
Ackermann floor box (see Figure 4).
Step 3. Insert the fixed tab into the slot in the Ackermann box.
Step 4. Adjust the size of the unit to fit the space in the box.
Step 5. Insert the tab on the adjustable mounting box to the appropriate
slot in the Ackermann box.
Step 6. Tighten the slide screws to fix the size of the unit.
