2 VS-808TP - Getting Started
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
Use Kramer high performance, high resolution cables
•Use only the power cord supplied with the device
Go to http://www.kramerelectronics.com to check for up-to-date
user manuals, application programs and to check whether firmware
upgrades are available (where appropriate).
2.1 Achieving the Best Performance
To achieve the best performance:
•Use only good quality connection 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 too tightly or too loosely. Leave a small amount of
slack
•Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
•Position your Kramer VS-808TP away from moisture, excessive sunlight and
dust
2.2 Using Twisted Pair Cable
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products; the Kramer: BC-DGKat524 (CAT 5 24 AWG), the
Kramer: BC-DGKat623 (CAT 6 23 AWG cable), and the Kramer: BC-DGKat7a23
(CAT 7a 23 AWG cable). These specially built cables significantly outperform
regular CAT 5/CAT 6/CAT 7a cables.

VS-808TP - Overview 3
3 Overview
Thank you for purchasing the Kramer VS-808TP 8x8 Twisted Pair Matrix Switcher.
This unique matrix switcher which utilizes economical TP (Twisted Pair) cabling
often pre-installed in buildings these days, routes and distributes signals both from
a local and/or remote source, and at extended ranges. It is designed especially for
installations where a high level of control possibilities is required from extended
distances. Typical uses include presentation and multimedia applications, as well
as long-range graphics distribution and control for schools, hospitals, security, and
stores.
The VS-808TP features:
•Eight inputs and eight outputs for remote connection to compatible TP
transmitters and receivers
•A switchable local input (built-in transmitter) and output (built-in receiver)
allowing direct connection of the signals (up to WUXGA, audio and RS-232)
for the units located near to the switcher (TP-133/TP-134 only)
•Follow or breakaway switching for audio signals
•Baud rate of up to 115200 for full-duplex RS-232
•Two-line LCD display for separate route indication of video, audio or RS-232
•Control via front panel buttons, RS-232, RS-485 and Ethernet
•15 user-programmable presets for quick-change configurations
•Kramer 2000 communication protocol (limited)
•100-230V AC worldwide power supply
•Standard 1U 19” rack mount size

Always switch off the power to any device before connecting it to your
VS-808TP. After connecting your VS-808TP, connect its power and
then switch on the power to the other devices.
Figure 3: Connecting the VS-808TP 8x8 Twisted Pair Matrix Switcher
To connect the VS-808TP as illustrated in the example in Figure 3:
1. For a local video and audio source connect:
A VGA source (for example, the graphics output of a laptop) to the PC
In 15-pin HD (M) connector
i

VS-808TP - Connecting the VS-808TP
An audio source (for example, the audio output of a laptop) to the
Audio In 3.5mm mini jack
2. For a local video and audio acceptor connect:
The PC Out 15-pin HD (F) connector to the video input of the acceptor
(for example, an AV system)
The Audio Out 3.5mm audio jack to the audio input of the acceptor
3. For remote inputs and outputs:
Connect up to eight compatible TP transmitters (for example,
TP-133/TP-125) to the TP INPUTS 1 to 8
Connect up to eight compatible TP receivers (for example,
TP-134/TP-126) to the TP OUTPUTS 1 to 8
Note: The TP-134 transmitter can be paired only with a TP-134 receiver, and the
TP-125 transmitter can be paired only with a TP-126 receiver. Do not use both the
TP-133/TP-134 and TP-125/TP-126 in the same system as depending on the
switcher setup only one will work.
6.1 Connecting a Serial Data Source to the VS-808TP RS-232
Data Port
You can connect a serial data source to the VS-808TP via RS-232 to control
remote acceptors (for example, monitors).
The RS-232 data source is connected to the RS-232 (DATA) port. A null-modem
adapter is not required for this connection and a straight-through cable can be
used.
6.2 Connecting a Serial Controller to the VS-808TP
You can control the VS-808TP via one of three types of serial connections:
•RS-232
•RS-485
•RS-422

VS-808TP - Connecting the VS-808TP

6.2.1 Connecting an RS-232 Serial Controller to the VS-808TP RS-232
Control Port
You can connect to the unit (the RS-232 CONTROL port) via a crossed RS-232
connection, using for example, a PC. A crossed cable or null-modem is required
as shown in method A and B respectively. If a shielded cable is used, connect the
shield to pin 5.
Method A (Figure 4)—Connect the RS-232 9-pin D-sub port on the unit via a
crossed cable (only pin 2to pin 3, pin 3to pin 2, and pin 5to pin 5need be
connected) to the RS-232 9-pin D-sub port on the PC.
Note: There is no need to connect any other pins.
Figure 4: Crossed Cable RS-232 Connection
Hardware flow control is not required for this unit. In the rare case where a
controller requires hardware flow control, short pin 1 to 7 and 8, and pin 4 to 6 on
the controller side.
Method B (Figure 5)—Connect the RS-232 9-pin D-sub port on the unit via a
straight (flat) cable to the null-modem adapter, and connect the null-modem
adapter to the RS-232 9-pin D-sub port on the PC. The straight cable usually
contains all nine wires for a full connection of the D-sub connector. Because the
null-modem adapter (which already includes the flow control jumpering described
in Method A above) only requires pins 2, 3 and 5 to be connected, you are free to
decide whether to connect only these 3 pins or all 9 pins.

6.2.2 Connecting an RS-485/RS422 Serial Data Source to the VS-808TP
To connect an RS-485/RS-422 serial data source to the VS-808TP:
•Connect the RS-485/RS-422 serial data source to the RS-485/RS-422
terminal block connector on the rear panel of the device as shown in
Figure 6or Figure 7

Figure 7: Wiring for an RS-422 Serial Data Source
6.3 Connecting to the VS-808TP via Ethernet
You can connect the VS-808TP via Ethernet using either of the following methods:
•A crossover cable (see Section 6.3.1) for direct connection to the PC
•A straight through cable (see Section 6.3.2) for connection via a network hub
or network router
After connecting the Ethernet port, you have to install and configure your Ethernet Port. For
detailed instructions, see the Ethernet Configuration Guide (Lantronix) in the technical support
section on our Web site http://www.kramerelectronics.com.
6.3.1 Connecting the Ethernet Port directly to a PC
A crossover cable is recommended for identification of the factory default IP
Address of the VS-808TP during the initial configuration.

VS-808TP - Operating the VS-808TP Locally via the Front Panel Buttons
7 Operating the VS-808TP Locally via the
Front Panel Buttons
The VS-808TP is operated using the front panels buttons as follows:
•Press the left (◄) or right (►) arrows to move backward or forward to select
the output of a switched pair
•Press the up (▲) or down (▼) arrows to move up or down through available
input channels
•Press Enter to activate changes
You can set or change several outputs together and then press Enter to finalize
the operation. Prior to pressing Enter the display reflects the changes but the
changes are not implemented.
When audio switching is active (the Audio button LED is lit) only audio channels
are switched.
Note: This mode is not supported in the Data & Audio Bypass mode for the
TP-125/126.
Note: Performing a video switch overwrites a previously implemented audio
switch.
Any of the local or remote inputs can be switched to any or all of the local or
remote outputs for the TP-133/134 only. For the TP-125/126, local input and
output ports cannot be used.
The PC In input can be used to accept signals from a local source. Inputs 1 to 8
accept signals from remote transmitters and Outputs 1 to 8 can be used to send
signals to remote receivers. The PC Out output can be used to send signals to a
local acceptor (for example, an LCD monitor).
When the VS-808TP is powered on, the following is displayed briefly:
