3 Overview
The TBUS-2 is a furniture-mounted connection bus that is easily installed into
a table or podium top. The TBUS-2 lets you connect any equipment to the
room’s presentation system installations via cable access or passive interfaces.
When not in use, you can lower the TBUS-2 flush into the table. The example
in Figure 1 shows the TBUS-2 in a table or podium top with a power socket
suitable for the US.
Figure 1: TBUS-2 Table Connection Bus
In addition, the TBUS-2 is:
Easily opened and closed by pressing down gently on the lid1
Modular in design, letting you tailor it according to your needs2
Available with different power outlet connections3
1 Due to its tilting angular construction, pneumatic lift and mechanical latching mechanism, it can be raised (when in use) or
lowered (when not in use)

To achieve the best performance:
Connect only good quality connection cables, thus avoiding 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 and position your Kramer TBUS-2
away from moisture, excessive sunlight and dust
Never place fingers inside the opening on each side of the
unit. This could cause serious injury because of the sharp
edges inside the TBUS-2.
Do not place heavy objects on top of the TBUS-2
Do not use excessive force to push down the top of the unit.

Figure 5: Cutout Dimensions
The thickness of the table should be 3” or less.
Before cutting the opening, confirm the dimensions and make sure that the
specifications have not changed.
Cut out the wooden surface in which you want to insert the TBUS-2. Take
care not to cause damage to the table.
Kramer Electronics is not responsible for any damage caused to the table

5.2 Inserting the TBUS-2 through the Cut-Out Opening
To install the TBUS-2, do the following:
1. Carefully insert the unit into the prepared opening.
2. Take the support brackets under the table and place them into the support
bracket grooves at the desired height (on both the front and rear sides of the
unit).
3. Make sure that the upper outer rim is situated parallel to the edge of the table.
4. Insert the table securing screw through the holes in the support brackets and
tighten them until they reach the table surface (from underneath).
5. Secure the cables.
Do not keep the cord too tight or too loose.
6. Connect the appropriate cables to the mounted Kramer inserts from
underneath.
Once you have connected the unit to mains power and connected the proper
cables, you may use the unit.
5.3 Installing the Required Kramer Inserts
You can install the Kramer inserts before or after installing the TBUS-2.
By default, the mounting surface includes a power socket (different power
sockets are available, see Figure 4), and six blank plates for optional video,
audio, telephone and network connectors.
Any of the Kramer inserts mounted to the connecting surface can be
rearranged or removed and replaced with Kramer inserts1 or connector
modules for interfacing A/V type signals.
To mount a Kramer insert or connector module, do the following:
1. Unscrew the two screws that fasten the blank plate to the connecting surface
and remove the blank plate.
2. Place the required Kramer insert over the opening, insert the two screws to fix
the Kramer insert in place, and tighten them.
