Control Panel, which is ideal for staging events, as well as:
that are clearly defined by function.
•Presentation applications that require a preview option
•Projection systems in conference rooms, board rooms, auditoriums, hotels,
and churches
1.1 About the VP-747T Presentation Switcher Control Panel
The Kramer VP-747T Presentation Switcher Control Panel is used to control
the VP-747 Universal Presentation Matrix Switcher / Scaler2
Note that the VP-747 needs firmware package Master FW 1.03 (Ver. 1.03 or
higher) to work with the VP-747T.
. The Kramer
VP-747T lets you remotely control switcher functions such as input selection,
transition effects (that include cut, fade, and wipes) and transition speed.
The package includes: the VP-747T,gooseneck lamp, null-modem adapter,
power supply, rack ears kit3, table-top brackets, 2 mini-XLR connectors and this
user manual4

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
2.1 Quick Start
This Quick start chart summarizes the basic steps when connecting a VP-747T:

Overview

3 Overview
The VP-747T is a unique presentation switcher control panel dedicated
specifically to control the VP-7471
•Enables special effect transitions between two sources via a robust T-bar
(used for manual control of transition speeds). Alternatively, the effect can
be implemented via a TAKE button, with a potentiometer to set the
transition speed
. It is ergonomically and aesthetically
designed in a rugged, professional 19" 4U rack-mountable metal enclosure with
the button layout in the style of the VP-747. In particular, the VP-747T:
•Features single button access to all inputs2
•Features dedicated single button actions for special effect selection,
immediate freezing and blanking, PIP display, and the choice of wipe
direction
—both for the Preview and for
the Program output—and the buttons have removable transparent caps to
allow labeling
•Has the user menu—conveniently located on the VP-747T panel—for
complete control of the VP-747 via its Preview OSD
•Consol can be simultaneously connected to up to four VP-747 machines,
using two mini XLR connectors and two terminal block connectors. The
communication is via RS-485, thus allowing the panel to be located more
than 1km from each VP-747
•Has an RS-232 port for field upgrading of its firmware
•With its angled faceplate, may be used freestanding on a table, or mounted
in a desktop or in a 19” rack (when your switcher is rack-mounted near to
the source devices, you can conveniently place the VP-747T on a table or
desk away from the equipment rack)
•Has a gooseneck lamp (included) that can be plugged into the consol for
use in low lighting environments
•Is powered by a 12V DC source
1 The VP-747 is also backward compatible to the VP-727T
2 Has two sets of input buttons: one that routes the input to the "PROGRAM" output and the other that routes to the
"PREVIEW" output

To achieve the best performance:
•Connect only good quality connection cables
•Avoid interference from neighboring electrical appliances, make sure not to
block the ventilation holes and position your VP-747T away from
moisture, excessive sunlight and dust. Be sure to position it straight in the
correct horizontal position on the table, desk or rack

5 Installing in a Desktop
This section describes how to install the VP-747T in a desktop1
To install the VP-747T in a desktop:
.
1. Cut an opening in the desktop—making the cut out on a wooden surface
using a sabre saw or a keyhole saw—at the location where you want to
insert the VP-747T. Figure 3 illustrates the cut out template (not to scale)
defining the surface that you have to cut out to install your VP-747T.
Figure 3: Cut Out Dimensions
2. Carefully insert the VP-747T unit into the prepared cut out opening, as
illustrated in Figure 4.
Figure 4: Inserting the VP-747T into the Prepared Cut Out Opening
1 Alternatively, you can use it freestanding on a table, or mounted in a 19” rack (see Section 6)

3. Insert the two mounting brackets through the bracket slits on both sides of
the VP-747T unit (see Figure 5).
Figure 5: Inserting the Mounting Brackets through the Bracket Slits
4. Be sure that the upper outer rim is situated parallel to the edge of the desktop.
5. Screw the mounting butterfly screws until they reach the desktop surface
(from the underneath).
6. Tighten the locking butterfly screws to lock the mounting butterfly screws.
The VP-747T unit is now secured in place, as illustrated in Figure 6.

7 Connecting the VP-747T
To connect the VP-747T to up to four VP-747 machines, as the example in
Figure 7 illustrates, do the following15F
1:
1. Connect the “TO VP-747” mini XLR connector of the VP-747T (by
one-to-one connection) to the VP-747, as follows:
MACH. # 1 to the mini XLR connector of the VP-747 which will be
recognized as machine # 1
MACH. # 2 to the mini XLR connector of the VP-747 which will be
recognized as machine # 2
2. Connect the “TO VP-747” 3-pin terminal block ports of the VP-747T (by
wired connection) to the VP-747, as follows (see section U7.2U):
MACH. # 3 to the mini XLR connector of the VP-747 which will be
recognized as machine # 3
MACH. # 4 to the mini XLR connector of the VP-747 which will be
recognized as machine # 4
3. Set the “T-Bar Optimization” mode in the “Transition” menu of the
VP-747 to On.
4. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity (not illustrated in UFigure 7U).
If you want to control several units simultaneously, press the MACHINE #
button until the letter A is selected in the 7-segment LED display (A=ALL).
One of the units must be connected to port #1 for units to be controlled
simultaneously.
1 Switch OFF the power on each device before connecting it to your VP-747T. After connecting your VP-747T, switch on its
power and then switch on the power on each device

7.1 Setting the Machine #
The VP-747T automatically recognizes the MACHINE # of each VP-747 unit.
For example, the VP-747 unit that is connected to the “TO VP-747” RS 485
port MACH. # 3 is recognized as the third VP-747 unit: MACHINE # 3.
To access this particular VP-747 unit from the VP-747T, press the MACHINE
# button1until the number 3 is selected in the 7-segment LED display2
