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
mode. Note that many USB cameras work in isochronous mode)
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
