2 TBUS-1A - 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
i
Go to http://www.kramerelectronics.com to check for up-to-date
user manuals, a complete list of Kramer wall plates and module
connectors, 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 TBUS-1A away from moisture, excessive sunlight and
dust

3 Overview
The TBUS-1A is a modular furniture-mounted connection bus that is easily
installed into a table or podium top. The TBUS-1A lets you connect any equipment
to the room’s presentation system installations via cable access or passive
interfaces (see
Figure 1). When the cables are not in use, they can be stored
inside the unit, covered by the lid and out of sight.
In addition, the TBUS-1A features:
• A modular design, letting you tailor the TBUS-1A according to your
requirements
• A brushed aluminum lid with a special opening for cable pass-through,
available in black and brushed clear (note, that other customized colors can
also be ordered)
• An inner frame that can be set to one of five possible height adjustments.
Note, that the inner frame is ordered separately
• Power socket openings that are suitable for any of the following power
sockets: for the USA, Germany (the Europlug), Belgium-France, Italy,
Australia, “Universal” for use anywhere (see compatibility restrictions in
Section
7), or Legrand type power sockets (for use with Legrand’s white
Mosaic™ series only)
Order the power sockets separately from Kramer Electronics
• Power socket openings for which you can order any of the following power
sockets: USA, Germany-EU, Belgium-France, Italy, Australia, “Universal” for

the surface of the table exactly where you want to install the TBUS-1A.
2. Attach the template to the table with the included screws (if using the cut out
template).
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).
i
The thickness of the table should be 76.2 mm / 3 inches or less.
Figure 4: Cut out Dimensions

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 site.

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.

To insert the pass through cables (for example, to connect a laptop) do the
following:
1. Remove the two screws attaching the split pass-through bracket.
2. Remove the split grommet.
3. Insert the cable through the rectangular opening.
4. Open the split grommet slightly and insert the required cables.
5. Place the split bracket around the grommet and position this assembly over
the inner frame.

5.6 Connecting the Cables
When replacing blank inserts with connector inserts (for example, VGA, audio,
HDMI and so on):
1. Insert the cables to their appropriate connectors from underneath.
2. Secure the cables to the tie holes on the TBUS-1A.
Do not secure the cables too tightly or too loosely. Leave a small amount of
slack.

If needed, you can adjust the inner frame to one of five possible heights to
accommodate large or bulky cables. To adjust, perform the following:
1. Remove the eight height adjustment screws (two screws on the front and
back, two screws on each side, as shown in
Figure 2), while supporting the
surface from underneath with your fingers.
2. Raise or lower the inner frame to the required height, insert the screws, and
tighten them in place.
