Introduction
Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world
of unique, creative, and affordable solutions to the vast range of problems that confront the
video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we
have redesigned and upgraded most of our line, making the best even better!
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.
Go to www.kramerav.com/downloads/RTBUS‑25xl to check for up-to-date user manuals,
application programs, and to check if firmware upgrades are available (where appropriate).
Achieving the Best Performance
•Use only good quality connection cables (we recommend Kramer high-performance,
high-resolution cables) to avoid interference, deterioration in signal quality due to poor
matching, and elevated noise levels (often associated with low quality cables).
•Do not secure the cables in tight bundles or roll the slack into tight coils.
•Avoid interference from neighboring electrical appliances that may adversely influence
signal quality.
•Position your Kramer RTBUS‑25xl away from moisture, excessive sunlight and dust.
This equipment is to be used only inside a building. It may only be connected to other
equipment that is installed inside a building.
Safety Instructions
Caution: There are no operator serviceable parts inside the unit.
Warning: Do not open the unit. High voltages can cause electrical shock! Servicing by
qualified personnel only.
Warning: Disconnect the power and unplug the unit before installing.

Installing the RTBUS‑25xl
To install the RTBUS‑25xl perform the following steps:
1. Drill a hole in the table (see Drilling a Hole in the Table on page 6).
2. Install the power socket (see Installing the Power Socket on page 6).
3. Secure the unit to the table (see Mounting the RTBUS‑25xl in the Table on page 7).
4. Connect the cables (see Connecting the Cables and Wires on page 8).
Drilling a Hole in the Table
To drill an opening in the table:
1. Using any standard cup bit drill with a diameter ranging from 111mm to 114mm (4.37in to
4.49in), drill a hole in the table in the desired location.
The thickness of the table should be 3in (76mm) or less.
2. Clean the table surface.
Take care not to damage the table. Kramer Electronics is not responsible for any damage
caused to the table.
Installing the Power Socket
Figure 3 shows an example of the Universal power socket housing which is one of the
optional power sockets for the RTBUS‑25xl, see Power Socket Options on page 4.
To install the power socket (purchased separately):
1. Close the RTBUS‑25xl lid.
2. Carefully insert the power socket housing so that
the power socket fits into the power socket
opening on the connecting surface and the four
standoffs fit the four screw holes on the
RTBUS‑25xl.
When positioned correctly, the IEC socket faces
downwards.
3. Screw the four screws included in the power
socket kit into the designated holes to fix the
power socket housing in place.
4. Unscrew the power connector lock.
5. Connect the IEC power cord to the IEC socket.

Connecting the Cables and Wires
Figure 4 illustrates how to connect the cables to the underside of the unit:
Figure 4: Connecting the Cables
Note that the cables shown in Figure 4 are 50cm long and have a MALE connector at the free
end so they can be plugged directly into the acceptors. You can extend these cables if
required.
Note that the connecting surface is an integral part of the RTBUS‑25xl enclosure and cannot
be detached.
We recommend that you use the Kramer C-AC AC Power Cord series to power the unit.
