3 Overview

The Kramer TBUS-3 is a high-quality, anodized aluminum, table-mounted
connection bus for boardrooms and conference rooms. Its attractive enclosure
is designed to provide maximum connectivity in the smallest possible
footprint. The unit is sturdy, cost-effective, and easy to install.

TBUS-3 includes:

 Four permanent components suitable for connecting a PC: one HD15F

connector, one Ethernet connector, one stereo audio 3.5mm mini jack,
and one USB-A connector

 One power socket - available in 7 versions: USA, UK, Germany-EU,

Belgium-France, South Africa, Australia, and “Universal” (for use
anywhere)

TBUS-3 is height-adjustable and thecover opens and closes manually,
keeping the cables and the connectors out of sight when not used.

To achieve the best performance:

 Use only good quality connection cables1 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 TBUS-3 away from moisture, excessive sunlight, and dust

5 Installing the TBUS-3 Table Connection Bus

To install TBUS-3, perform the following steps:

2. Adjust the height of the connecting surface (see section 5.2).

3. Install TBUS-3 in the cut-out opening (see section 5.3).

4. Connect the cables (see section 5.4).

5.1 Cutting an Opening in the Table

To cut an opening in the table:

1. Place the included cut-out template on the surface of the table where you want

to install TBUS-3.

2. Attach the template to the table with the included screws.

3. Following the inside edge of the template, cut a hole in the table surface with a
sabre or keyhole saw according to the dimensions shown in Figure 4 (not to
scale).

Note: The thickness of the table should be 3 inches or less.

4. Unscrew and remove the template from the surface of the table and clean the
table surface.
Take care not to damage the table.
If needed, you can download a full-scale template from our Web site1.

Kramer Electronics is not responsible for any damage caused to the table

5.2 Adjusting the Height of the Connecting Surface

If needed, you can adjust the connecting surface to one of four possible
heights to accommodate large or bulky cables. By default, the height is set to
the second level from the top. To adjust, perform the following:

1. Remove the eight height adjustment screws (two screws on each side, as
shown in Figure 2), while supporting the surface from underneath with your
fingers.

2. Raise or lower the connecting surface to the required height, insert the
screws, and tighten them in place.

5.3 Installing TBUS-3 in the Cut-Out Opening

To install TBUS-3 in the opening:

1. Remove the protective rubber guard from around the outer rim of the
mounting plate. Beware of the sharp edge!

2. Carefully insert the unit into the prepared opening (see Figure 5).

3. Take the support brackets under the table and place them into the support
bracket grooves on both sides of the unit (see Figure 2).

4. Verify proper alignment of the unit before tightening the mounting screws.

5. Screw both mounting butterfly screws upward until they reach the table
surface (from underneath). Tighten firmly (see Figure 5).

6. Screw the locking butterfly screws downward until tight against the mounting
bracket.
