VA-1USB-T/VA-1USB-R - 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
Go to http://www.kramerelectronics.com/support/product_downloads.asp
to check for up-to-date user manuals, application programs, and to check if
firmware upgrades are available (where appropriate).
2.1 Achieving the Best Performance
To achieve 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 VA-1USB-T and VA-1USB-R away from moisture,
excessive sunlight and dust
This equipment is to be used only inside a building. It may be
connected only to other equipment that is installed inside a building

2.2 Safety Instructions
Caution:
No operator serviceable parts inside the unit
Warning:
Use only the Kramer Electronics input power wall
adapter that is provided with the unit
Warning:
Disconnect the power and unplug the unit from the wall
before installing
2.3 Recycling Kramer Products
The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC
aims to reduce the amount of WEEE sent for disposal to landfill or incineration by
requiring it to be collected and recycled. To comply with the WEEE Directive,
Kramer Electronics has made arrangements with the European Advanced
Recycling Network (EARN) and will cover any costs of treatment, recycling and
recovery of waste Kramer Electronics branded equipment on arrival at the EARN
facility. For details of Kramer’s recycling arrangements in your particular country
go to our recycling pages at http://www.kramerelectronics.com/support/recycling/.
2.4 Shielded Twisted Pair/Unshielded Twisted Pair
We recommend that you use Shielded Twisted Pair (STP) cable and stress that
the compliance to electromagnetic interference was tested using STP cable.
There are different levels of STP cable available and we advise you to use the
best quality STP cable that you can afford.
For the VA-1USB-T and VA-1USB-R pair we recommend the use of shielded,
twisted pair (STP), non-skew-free Kramer BC-STP cable.

VA-1USB-T/VA-1USB-R - Overview
3 Overview
The VA-1USB-T and VA-1USB-R are a high-performance, TP (Twisted Pair)
transmitter and receiver for communicating USB, bidirectional RS-232 data and
unidirectional IR signals over extended distances using CAT 5/6 cable.
The VA-1USB-T encodes USB signals and RS-232 data and transmits them over
CAT 5/6 cable as a TP signal. The VA-1USB-R decodes the signal from the TP
into USB signals and RS-232 data. The VA-1USB-R also acts as a 4-port USB
hub and receives IR signals for transmission back to the VA-1USB-T.
More specifically, the VA-1USB-T and VA-1USB-R support:
USB 2.0 high speed and USB 1.1 signals (bulk mode, not isochronous)
True Plug and Play operation without drivers
All major operating systems
Full duplex, bidirectional RS-232 transmission
Local and remote control of devices via the serial port
Operation up to 100m (328ft) apart
Web pages for maintenance and configuration
Automatic Ethernet speed selection
Up to 16 independent pairs of devices on a single network

USB Transmitter and Receiver
This section defines the:
VA-1USB-T USB Transmitter (see Section 4.1)
VA-1USB-R USB Receiver (see Section 4.2)
4.1 Defining the VA-1USB-T USB Transmitter
In addition to encoding and transmitting the USB and RS-232 signals, the
VA-1USB-T outputs the IR signal received from the VA-1USB-R.
RS-232 commands and data flow bidirectionally allowing status requests and
control of a destination unit.

4.2 Defining the VA-1USB-R USB Receiver
The VA-1USB-R decodes the USB signal and RS-232 data from the TP link sent
from the VA-1USB-T. The receiver distributes the USB signal across four USB
ports (acting as a USB hub) and outputs the RS-232 data. The VA-1USB-R
receives an IR signal via its IR sensor and sends it over the TP link to the
VA-1USB-T.
