- 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.
