3 Overview
The Kramer TBUS-4 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-4 includes:
Eight permanent components suitable for connecting two PCs:
two HD15F connectors, two Ethernet connectors, two stereo audio
3.5mm mini jacks, and two USB-A connectors
Two power sockets – available in 7 versions: USA, UK, Germany-EU,
Belgium-France, South Africa, Australia, and “Universal” (for use
anywhere)
One optional insert kit

to replace one power socket
TBUS-4 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 cables
2
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-4 away from moisture, excessive sunlight, and dust

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-4.
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

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.

surface, keep the screws, and remove the power module from below.
2. Place and align the insert under the opening, insert the two screws to fix the
insert in place, and tighten them.
