Carmichael, California - February 21, 2000 - Trans Digital Corporation
of Carmichael, California introduced today new Trans Processor chip,
which incorporates developed by Trans Digital Write-Back Transfer
Engine.
The new Trans Processor chip, result of 5 years of R&D, allows for
the fastest effective data transfer between PCs and between PCs and
connected devices. It outperforms all other transfer technologies
over copper wires, used for networks and for connection of peripherals
to computers, in terms of transfer speed on distance of up to 100m.,
with very low power draw.
The new chip has improved transfer rate vs. the previous versions.
It allows to transfer at the sustained rate of 8 MB/sec, driven by
Write-Back Transfer Engine, implemented on silicon of the Trans
Processor. The parallel transfer of data is asynchronous, speed
adaptive, immune to interferences, with negligible emission levels.
The transfer rate can be increased further, up to the effective
transfer rate of 40 MB/sec, which is 400 times faster in comparison
to popular Ethernet 10 BASE-T networks.
Trans Processor was developed to allow operation in ultra high speed
mode, using Write-Back Engine technology, as well as in standard
parallel port mode for compatibility with existing devices like
printers, Zip drives, etc.
Transparent media scalability is an additional advantage of this
technology, since it can operate using 25 conductors of the Universal
Parallel Port or only 8 or 4 wire phone lines using popular unshielded
cables-twisted pairs and modular RJ45 or RJ11 jacks.
With further improvements, the effective transfer rate is over 1MB/sec,
using UTP (Unshielded Twisted Pairs) 8 wire cables - effectively over
8-10 times faster in comparison to popular Ethernet 10 Base T and
100 Base TX with 10 and 100 Mbps bandwidth. With 4 wire phone lines,
this technology allows for over 200-500 times speed improvement vs.
RS232 serial transfer. With a Network Access Layer of TCP/IP, it
provides future ultra-high speed, low power Internet connectivity.
The new Trans Processor chip is incorporated in Trans PC Card - Type I
card that fits in all PC Card slots. Due to speed limitation of the PC
Card interface, the effective transfer rate is reduced to 800KB/sec
while transferring between PCs and to 2MB/sec while acquiring the data
(reading data from fast device).
Trans PC Card was initially developed for Notebook PCs and
Hewlett Packard HP200LX Palmtops providing:
Transfer between two Notebook PCs of 48 MBytes of AutoCAD Release 13
with over 500 files in 23 directories takes about 1 minute while disks
reading and writing - 3 minutes, total 4 minutes. Copying the same
files between directories of the same disk requires 5 minutes.
Transferring 8 MBytes file from one disk of a Notebook to another
takes 20 sec. Transferring 8MBytes file between emulated RAM disks
takes 11 sec. Downloading the same file over the Internet with 56 kbps
modem takes about half hour. Transfer of 8MB uncompressed digital
images data from a digital camera to a PC, using currently available
RS232 serial connection, requires over 20 minutes, using USB interface
with 12Mbps bandwidth takes about 1 minute in comparison with only 4
seconds using Trans PC Card. Trans Write-Back Engine transfer of the
digital image is also about 3 times faster than transferring the same
image to a flash memory card ("digital film").
Trans PC Card has very low power consumption - about 20 mW, therefore
it is ideal for battery operated mobile devices like Palmtops and
digital cameras. In addition, one pin of Trans Universal Parallel
Port supplies power to drive devices connected to the PC.
The Trans PC Card is the proof of concept for Write-Back Transfer
Engine Technology. The Card, besides the Trans Processor, incorporates
a flash memory device with software for transfer. Currently it
contains Trans PC programs for an instant transfer/management of files
and CIC (Card Installation Client) program for installation of a
parallel port. The re-programmable flash memory chip emulates
the disk drive thus eliminating the need for a floppy drive
during installation.
The Trans PC Card installs as a Plug and Play parallel port
with DOS, Win95/98 and Linux. With Windows2000 the card auto-installs
(automatic installation with insertion of the card into PC slot).
The transfer software, developed in Assembler by Trans Digital Corp.,
runs under DOS 5.0 or later, Windows 95 and 98. It operates in a DOS
window as a powerful Command Line Processor with syntax similar to Xcopy
command with many options or as a Transfer Manager "point and shoot"
graphical overlapping windows interface supporting mouse drag and drop
capabilities.
Universal Parallel Cable was developed to connect Universal Parallel
Ports of Trans PC Cards in order to utilize the full power of Trans
Processor. Universal Parallel Cable is multifunctional, providing future
Universal Connectivity between PCs and peripheral devices, due to its
unique wiring. It can be used for ultra high speed transfer, printing,
connection of digital cameras and other future peripheral devices to PC
if devices are equipped with Universal Parallel Port.
Trans Digital also developed 3ft. Trans Flex Cable that is used with
Trans PC Card to support standard parallel port devices. This special
cable, with two (male and female) DB25 pin connectors mounted back to
back, is used for: transfer, printing and connection to existing
standard peripherals (like Zip drive).
Trans PC Card is available now. The retail price of Trans PC Card with
Trans Flex Cable is $179.00. The Universal Parallel Cable is $29.00
