You do not have to connect all the outputs, connect only those that
are required.
5.1 Connecting the VCO-8 / VCO-16
To connect the VCO-8 / VCO-16, as illustrated in the example in Figure 4:
1. Connect an HDMI source (for example, a media player) to the HDMI INPUT
connector.
Alternatively, you can connect the DVI connector on the DVD player to the
HDMI connector on the VCO-8 / V CO-16 via a DVI-HDMI adapter
2. If required, connect a looped HDMI acceptor (for example, from the HDMI
LOOP connector to the INPUT of another VCO device), see Section 6
.
3. Connect the HDMI OUT connectors to HDMI acceptors (for example, LCD
displays): 1 to 8 fo r VCO-8, 1 to 16 f or VCO-16.
4. Connect the power cord (not shown in Figure 4
5. Connect the ETHERNET port, see Section 8.2.
10 VCO-1, VCO-8, VCO-16 - Connecting the VCO-1, VCO-8, VCO-16
).

5.2 Connecting the VCO-1
To connect the VCO-1 as illustrated in the example in Figure 5:
1. Connect an HDMI source (for example, a media player) to the HDMI IN
connector.
Alternatively, you can connect the DVI connector on the DVD player to the
HDMI connector on the VCO-1 via a DVI-HDMI adapter.
2. Connect the HDMI OUT connector to an HDMI acceptor (for example, an
LCD display).
3. Connect the 5V DC power adapter to the power socket and connect the
adapter to the mains electricity (not shown in Figure 5
4. Connect the ETHERNET port, see Section 8.2.
).

and can be set with its own specific overlay.
6 Looping the VCO-8 and VCO-16
In the following example, two VCO-16 devices are connected via the LOOP
connector to produce a 32 port video overlay. One video input is distributed to 32
outputs with individual content overlay set to each of the 32 outputs.
To connect two looped VCO-16 units with 32 outputs, as shown in the example in
Figure 6
, do the following:
1. On the first VCO-16 unit, connect:
A video source to the HDMI INPUT connect or (for exampl e, a Blu-ray
player)
The OUT HDMI connectors to acceptors (for example, displays)
2. Connect the LOOP HDMI connector of the first unit to the INPUT HDMI
Connector of the second unit.
3. On the second VCO-16 unit, connect the OUT HDMI connectors to
acceptors (for example, LCD displays)
In the Kramer VCO Setup App, each device in the daisy chain has a
separate IP address and each of the 32 outputs is given a unique name
In the same way you can loop an almost unlimited number of devices if HDCP is
not in use and up to five devices when HDCP is in use.
When an HDCP source, such as a Blu-ray player or a SAT receiver, is
used the number of looped devices may be lower.

7 Using the Kramer VCO Setup Application
Use the Kramer VCO Setup App to manage and send an overlay to each output.
The VCO Setup App allows you to take a template which can include one or more
graphic files and a playback program, modify the program and settings if needed,
and load the resulting overlay onto specific device outputs.
The graphic files can be prepared with any graphics program such as Adobe
Photoshop, Paint.NET and so on. They can include transparency, animation and for
the PSD format also editable fields.
With the playback program you can set the size and position of the overlay on the
screen and control its movement across the screen as well as its transparency
level. Each overlay playback program can be scheduled to appear at certain times
and on certain days. You can also control the frequency and rate a playback
appears.
This section describes how to:
• Install the application (see Section
• Set the application language and add devices (see Section 7.2).

7.4 Scheduling the Overl ays
Once an overlay is loaded to an output of a Kramer VCO device, it will keep playing
on that input until a different overlay is loaded to that device/output (you can
manually play, pause or stop an overlay).
The Scheduling feature lets you load overlays to devices and create playlists which
automatically load lists of overlays to one or many VCO devices. This enables the
creation of complex scenarios for multiple pre-configured overlays to load to one or
many VCO devices according to a predefined schedule.
Playlist: a playlist includes a list of events that will play according to a predefined
schedule. You can create multiple playlists. Each playlist is given a specific name.
Event: the event includes a list of overlays that can be bound to different VCO
outputs. Each event can have multiple overlays. An Event is part of a playlist and
can be scheduled and repeated as needed.
For example, a store playlist that includes two events, one for opening hours and
the other when the store is closed (they can be called Day and Night). The VCO
device includes eight outputs and all of them show the same images during
opening hours and other images for when the store is closed. Each event includes
a list of overlays that are scheduled to play at the appropriate time (this can happen
at certain days in a week, at certain time each day, and so on).
There is no limit to the number of overlays that are included in an event and to the
number of events that can be included in a playlist.
You can schedule an event after configuring the overlays and binding them to the
outputs of VCO devices. If you need an overlay to be loaded to several VCO
devices (outputs), you need to duplicate these overlays and bind them to other
devices (outputs).
We recommend that you logically create folders and subfolders in the My
Overlays list for the different overlays and out puts to make it easy to

8 Defining an IP Address for a Device
When a static IP address is used, the first three numbers of the address are defined
via the labeling software and the fourth number is set by the DIP-switches on the
rear panel of the machine (see Figure 75
for large systems.
Figure 75: Setting the IP Address
). This is very usef ul when setting labels
8.1 Setting a Static IP Address
The first three IP numbers are set via VCO Setup Application Machine Wizard (see
Section 7.2.3), or via K-Upload (see Section 8.1.2
DIP-switches (see Section 8.1.1). You can also set the DHCP mode (see
Section 8.1.3)
) and the last number is set by the
8.1.1 Using the DIP-Switches
The last IP number is set by the DIP-switches at the rear of the machine (in binary
code, 8 bits). Use 8-bit binary code for this number (DIP#1 is LSB, DIP#8 is MSB).
Valid numbers are 1 to 254 (default factory setting is 39).

purposes only and its syntax may vary per device.
10 Communication Protocol
The VCO-1, VCO-8, VCO-16 Video Content Overlay Solution can be operated
using the Kramer Protocol 3000 serial commands. The command framing varies
according to how you interface with the VCO-1, VCO-8, VCO-16. In the following
example, the firmware version number command is entered as follows:
• Terminal communication software, such as Hercules:
The framing of the command varies according to the terminal
communication software. This command is used for demonstration
• K-Touch Builder (Kramer software):
VCO-1, VCO-8, VCO-16 - Communication Protocol 77
• K-Config (Kramer configuration software):
All the examples provided in this section are based on using the
Kramer K-Config software.
You can enter commands directly using terminal communication software (e.g.,
Hercules) by connecting a PC to the Ethernet port on the VCO-1, VCO-8, VCO-16.
To enter CR press the Enter key (LF is also sent but is ignored by the command
parser).
Commands sent from various non-Kramer controllers (e.g., Crestro n) may require
special coding for some characters (such as, /X##). For more information, refer to
your controller’s documentation.
For more information about:
• Using Protocol 3000 commands, see Section
10.1
• General syntax used for Protocol 3000 commands, see Section 10.2
• Protocol 3000 commands available for the VCO-1, VCO-8, VCO-16, see
10.3
Section
10.1 Understanding Protocol 3000
Protocol 3000 commands are structured according to the following:
• Command – A sequence of ASCII letters (A-Z, a-z and -). A command and
its parameters must be separated by at least one space.
• Parameters – A sequence of alphanumeric ASCII characters (0-9, A-Z, a-z
and some special characters for specific commands). Parameters are
separated by commas.
• Message string – Every command entered as part of a message string
begins with a message starting character and ends with a message closing
character.
78 VCO-1, VCO-8, VCO-16 - Communication Protocol
The maximum string length is 64 characters.
A string can contain more than one command. Commands are
separated by a pipe (|) character.
• Message starting character:
# – For host command/query
~ – For device response
• Device address – K-NET Device ID followed by @ (optional, K-NET only)
• Query sign – ? follows some commands to define a query request
• Message closing character:
CR – Carriage return for host messages (ASCII 13)
CR LF – Carriage return for device messages (ASCII 13) and line-feed
(ASCII 10)
• Command chain separator character – Multiple commands can be chained
in the same string. Each command is delimited by a pipe character (|). When
chaining commands, enter the message starting character and the message
closing character only at the beginning and end of the string.
Spaces between parameters or command terms are ignored.
Commands in the string do not execute until the closing character is
entered. A separate response is sent for every command in the
chain.

10.2 Kramer Protocol 3000 Syntax
The Kramer Protocol 3000 syntax uses the following delimiters:
• CR = Carriage return (ASCII 13 = 0x0D)
• LF = Line feed (ASCII 10 = 0x0A)
• SP = Space (ASCII 32 = 0x20)
Some commands have short name syntax in addition to long name syntax to
enable faster typing. The response is always in long syntax.
The Protocol 3000 syntax is in the following format:
• Host Message Format:
• Simple Command – Command string with only one command without
addressing:
Command SP Parameter_1,Parameter_2,…
80 VCO-1, VCO-8, VCO-16 - Communication Protocol
• Command String – Formal syntax with command concatenation and
addressing:
Command_1 Parameter1_1,Parameter1_2,…|
Command_2 Parameter2_1,Parameter2_2,…|
Command_3
Parameter3_1,Parameter3_2,…|…
• Device Message Format:
• Device Long Response – Echoing command:
