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/VP-554X to check for up-to-date user manuals,
application programs, and to check if firmware upgrades are available (where appropriate).
Achieving 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 VP-554X away from moisture, excessive sunlight and dust.
Safety Instructions
Caution:
•This equipment is to be used only inside a building. It may only be connected to other
equipment that is installed inside a building.
•For products with relay terminals and GPI\O ports, please refer to the permitted rating
for an external connection, located next to the terminal or in the User Manual.
•There are no operator serviceable parts inside the unit.
Warning:
•Use only the power cord that is supplied with the unit.
•Disconnect the power and unplug the unit from the wall before installing.
•Do not open the unit. High voltages can cause electrical shock! Servicing by qualified
personnel only.
•To ensure continuous risk protection, replace fuses only according to the rating
specified on the product label which is located on the bottom of the unit.

To connect VP-554X as illustrated in the example in Figure 3:
1. Connect an HDMI source (for example, a Blu-ray player or laptop) to the HDMI IN
connector (from 1 to 6).
Alternatively, you can, for example, connect the DVI connector on a DVD player to the
HDMI connector on the VP-554X via a DVI-HDMI adapter. When using this adapter, you
can connect the audio signal via the terminal block connector
2. Connect a VGA source to the PC IN 15-pin HD connector .
3. Connect an HDBT IN transmitter (for example, TP-580Txr) to the HDBT IN RJ-45
connectors (from 1 to 4).
4. Connect the USB IN ports (from 1 to 4) (for example, laptops) and USB OUT port
(for example, a smart whiteboard).
5. Connect the audio inputs (see Connecting a Balanced/Unbalanced Stereo Audio Source
to the Input on page 11) to the:
▪Audio input 5-pin terminal block connectors (from 1 to 8).
▪Up to 2 microphones to the MIC 3-pin terminal blocks (1 to 2).
6. Connect OUT 1 to OUT 4:
▪OUT HDMI and/or HDBT output to an HDMI acceptor (for example a display / smart
whiteboard) and/or an HDBT receiver (for example, TP-580Rxr).

Connect to a pair of loudspeakers, by connecting the left loudspeaker to the “L+” and
the “L-” terminal block connectors, and the right loudspeaker to the “R+” and the “R-”
terminal block connectors. Do not Ground the loudspeakers.
8. Connect the:
▪RS-232 EXT CONTROL 3-pin terminal block connector port to an RS-232
controlled device to control it via commands sent from the VP-554X.
▪RS-232 CONTROL 3-pin terminal block connector port to a PC to control the
unit.
9. Connect the MUTE 2-pin terminal block contact-closure remote-control pins to a switch
to mute/unmute the audio output by momentarily pressing the switch (not shown in
Figure 3).
10.Connect the ETHERNET port (on the front panel), DATA port and/or CONTROL
port (on the rear panel), to the Network (see Operating via Ethernet on page 27).

Connecting to VP-554X via RS-232
You can connect to VP-554X via an RS-232 connection using, for example, a PC.
VP-554X features an RS-232 3-pin terminal block connector allowing the RS-232 to control
VP-554X.
Connect the RS-232 terminal block on the rear panel of VP-554X to a PC/controller, as
follows:
From the RS-232 9-pin D-sub serial port connect:
•Pin 2 to the TX pin on the VP-554X RS-232 terminal block
•Pin 3 to the RX pin on the VP-554X RS-232 terminal block
•Pin 5 to the G pin on the VP-554X RS-232 terminal block
