o 1st ... product development tools for OEMs and developers
o PC MAG Editor's Choice for Ethernet parallel port NIC
o most total network adapters -- 6 and counting...
o most total parallel port peripherals -- 17 and counting...
We have in-depth experience with the wonderful and sometimes bizarre
world of the PC parallel port and have served on both the EPP and
IEEE 1284 standards committees. Having created more than a dozen
parallel port devices with their associated drivers and software
utilities, we are the most experienced source for off-the-shelf
technology, developer tools and components, and contract services.
Here are a few of our current and forthcoming products that you may
find interesting.
Parallel Port Developer's Kits
-----------------------------
Pipx was constructed with Parallel Technologies' advanced parallel
port software, which has been used in over 15 parallel port devices
including network adapters, parallel port disks, parallel port
wireless IR adapters, parallel port MIDI interfaces, and so forth.
This software includes support for all types of ports, IO code
that is extremely resistant to port idiosyncrasies, and full
autodetection of all port hardware features. The code is very well
documented. A selection of sample drivers for parallel port devices
is also available.
Kit Versions
------------
Device Level One Kit
Hardware schematics, timing diagrams, access methods and
all other hardware information required to implement basic
peripheral devices that are compatible with all types of
parallel ports (4BIT, 8BIT, semi-8BIT, EPP, ECP).
Software section includes sample source code for register
and block data access to the sample device.
Device Level Two Kit
Includes Level One Kit PLUS ... details on very-high speed
IO techniques, designing passthrough ports, daisychain and
multiplexor compatible Multiport devices. Also includes
full EPP and IEEE 1284 specifications.
IEEE "Super 1284" Printer Kit
Prototyping board, FPGA equations, assembler source for
1284 negotiation, Windows 3.1 driver source.
Allows the rapid development of IEEE 1284 compatible printers.
Also ... Super 1284 goes BEYOND the IEEE 1284 spec to allow
full transparent bi-directional I/O on 4BIT, semi-8BIT, and
8BIT ports. This means that Super 1284 printers can operate
bi-directionally at very high speeds (upwards of 250Kbyte/sec)
even on the installed base of "old-fashioned" ports.
Super 1284 maintains complete compatibility with IEEE 1284
ports and printers ... it is a compatible enhancement that
allows printer vendors to support high-speed operation
independently of EPP and ECP port availability.
Connectivity Kit
Includes hardware schematics for 4BIT (laplink compatible),
8BIT, ECP, and the Universal Parallel Port Cable.
Includes driver source code for parallel port network drivers.
This kit allows connectivity vendors to support very fast
parallel port connections (500 Kbytes/sec on the ECP and
Universal Cable) and to develop compatible products for the
new ParaNet standard.
Parallel -- the Parallel Port Information Utility
-------------------------------------------------
A handy utility which examines your system's parallel ports and
reports the Port Type, IO address, IRQ level, BIOS name, and an
assortment of informative notes and warnings in a compact and easy
to read display. The output may be redirected to a file for tech
support purposes. Parallel uses very sophisticated techniques for
port and IRQ detection and is aware of a broad range of quirky port
features.
Parallel is the definitive parallel port Tech Support tool.
Parallel is Freeware, subject to a restricted license agreement.
It may be used free of charge for any personal, non-commercial
purpose. Vendors should contact us regarding commercial licenses.
A forthcoming commercial version of Parallel will use an active
loopback connector enabling many new features including detailed
resolution of port IO behavior and effective throughput testing.
Parallel Port Networking
------------------------
Now you can network two PCs using your favorite network software
with just a parallel port cable between the systems.
Supports: Netware Lite, Workgroups for Windows, MS Lan Manager,
various TCP/IP systems, and other network operating systems that
use the ODI, NDIS, or packet driver interfaces.
Performance is better than you might expect, ranging from a low
end of 40 KBps between 4BIT ports all the way up to an effective
200 KBps between EPP ports using our TURBO cable. This upper range
is better than many ethernet ISA cards.
The drivers are available with or without cables, and existing cable
types typically used with laplink type products are also supported.
The MultiPort Parallel Port Expansion System
--------------------------------------------
The MultiPort 4-port multiplexor turns your parallel port into
a general purpose expansion system, capable of supporting up to
four simultaneously operating parallel port peripherals including
network adapters, portable hard drives, tape backup units, CDROMs,
floppies, and so forth. For example, you can use the MultiPort Mux
to attach a network adapter, a hard disk, a CD-ROM, and a printer,
all operating together through a single parallel port.
Now your laptop (and desktop) can enjoy a full range of peripherals
with all the portability, sharability, and convenience of parallel
port devices.
OEM Products
------------
Most of our products are available for OEM licensing, including
network adapters, EPP-capable hard disks, parallel-SCSI interface,
parallel MIDI adapter, and the MultiPort parallel port expander.
Also available are numerous off-the-shelf hardware and software
components including: device schematics, FPGA equations, DOS and
Windows driver source code, etc, etc.
Development Services
--------------------
We specialize in contract development of parallel port peripherals
and associated software including DOS and Windows device drivers.
Our broad and deep experience with parallel port devices and our
commitment to specialization allows us to design, implement, test,
and support them very efficiently.
You might be interested in our 30/90 development offer. We propose
to convert any ISA peripheral into a parallel port device in only
30 days to prototype, 90 days to production.
We also offer more limited development support, such as developing
additional devices drivers for existing peripherals.
We are quite experienced with EPP ports and are ready to upgrade
your existing parallel port devices to full EPP performance.
Consulting and Training
-----------------------
In support of in-house development, you will find our consulting
and training services invaluable in avoiding the pitfalls of
parallel port development while achieving the highest possible
product performance and quality.
