FarSync OEM T4U - Intelligent 4 port PCI / PCI-X (Universal PCI) WAN Communications Card

FarSync OEM T4U

This product has been replaced by the FarSync T4U

The FarSync OEM T4U PCI / PCI-X intelligent card is a high performance 4 port communications Universal PCI card suitable for providing a hardware platform for a wide variety of WAN requirements.

Overview

The FarSync OEM T4U card and software is designed to provide high performance hardware communications solutions for companies who wish to quickly develop their own communications products without incurring the cost of having to develop and approve hardware. The Developers Toolkit is included with the product.

The product includes support for the standard Windows SDCI API. This provides applications with direct access to the card's 4 communications ports for bit synchronous (HDLC) framing and also transparent bitstream operation for video and voice. Full documentation and a sample application demonstrating both modes of operation is provided.

Support is included for the Linux Raw Sockets API that allows HDLC frames and transparent bitstreaming data to be sent and received. Full documentation, source code for the driver and a sample application demonstrating both modes of operation is provided.

The transparent bitstream option available with the APIs is suitable for video and voice such as T-DMB (Digital Multimedia Broadcasting), DAB (Digital Audio Broadcasting) ETI (Ensemble Transport Interface - ETSI EN 300 799).

For embedded development royalty free source code is provided for the executive and synchronous line drivers together with a sample embedded application, test programs and utilities that allow you to get the card working straight out of the box.

Typical Applications

The FarSync OEM T-Series adapters are suitable for a very wide variety of applications, including for example:

  • High speed multi-port HDLC framing support for non standard or specialist protocols
  • Interfacing DAB ETI (Ensemble Transport Interface - ETSI EN 300 799) transparent bit streams to Servers
  • Interfacing MPEG Video bit streams T-DMB ETI to Servers
  • Interfacing high speed MPEG Video bit streams to Servers
  • Watchdog systems
  • Data generators for test systems
  • Engineering monitoring and control systems

FarSync OEM T4U Hardware

The card comprises a AMD processor with 1 Mbyte of on board no wait state SRAM. The whole memory space may be mapped via the PCI / PCI-X interface to the PC/Server. The contains a quad embedded HDLC / transparent bitstream controller with SDMA access (128 buffers per port) and a full range of timers.

Network Interfaces

The T4U supports 4 synchronous ports which can run to speeds of up to 10 Mbits/s full duplex, the total bandwidth supported by the adapter is 64 Mbits/s. There is also an option to fit a quad port asynchronous UART EXAR 16C654 chip. Individual ports can be soft selectable to operate asynchronously up to 115 Kbits/s.

The multi function line drivers available on all ports support RS232C (V.24), X.21 (RS422, V.11), V.35, RS530 and RS449. The network interfaces are all soft configurable and protected from static charges by ESD protection devices.

The T4U supports accurate internal clock generation at a wide range of standard frequencies from 9,600 baud to 8.192 Mbits/s. The clocking speed of all 4 ports are individually selectable. Internal clocking is selectable for the RS232C, X.21 and RS449 network interfaces. Dual clocks can be generated in V.11 mode if required.

PC / Server PCI and PCI-X Compatibility

The FarSync T4U card is suitable for systems with a PCI or PCI-X bus, covering single processor systems, all multiprocessor systems and processors featuring HyperThreading technology, including Pentium 4, Xeon and Xeon-MP CPUs. The card is PCI revision 2.2 compliant with support for both 3.3 and 5 volt signalling, the power for the card is taken from the 3.3 volt supply rail. The FarSync OEM T4U card may be fitted in either 32-bit PCI bus slots or 64-bit PCI-X bus slots as this Universal PCI card will work perfectly well in both.

Windows SDCI API

The FarSync OEM T-Series cards and software provides support for an extended SDCI (Synchronous Dumb Card Interface) API. The API allows applications to exactly control the type of data sent and received in both bit synchronous (HDLC framed) data and transparent bitstream formats.  The SDCI SDK contains everything a user needs to rapidly develop and test applications for such requirements as supporting specialist synchronous protocols or transparent data requirements such as Audio, MPEG Video, DAB and DRM.

On the FarSync OEM T4U+Async (FS5441) model to operate a port with asynchronous data under Windows XP, Windows 2000 and Vista, the FarSync driver supports a subset of the standard Win32 COMM API as detailed in Microsoft's MSDN Documentation. This enables applications that currently interface to standard serial ports on Windows to be easily ported to use FarSync ports in asynchronous mode. As an alternative to using the Win32 COMM interface, SDCI clients also have the option of using much of the same code to support FarSync ports in either asynchronous or synchronous modes e.g. the same data transfer IOCTLs.

Drivers for the FarSync OEM T-Series range of cards are provided for Windows XP, 2000, Server 2003 and NT4. An easy to follow sample application with support for both modes of operation is provided complete with source code to illustrate how the interface can be used, see further information on the SDCI API.

Easy installation and fast configuration are features when using the SDCI Interface on Windows, On-line help, documentation and GUI based test utilities are provided. T-Series cards are 'plug-and-play' compatible supporting Windows XP, 2000 and Server 2003. Typically 12 or more cards (48+ ports) can be supported on a single Server; the card limit is only dependent on the PCI slots resources available in the Server.

Linux Raw Sockets API

The Linux API allows applications to send and receive HDLC format (bitsync) frames and also transparent bit streams with the raw sockets based API. The sample application demonstrates both modes of operation.

Data rates of up to 10 Mbits/s are supported, with all the ports individually selectable for speed, clocking direction and mode of operation (HDLC or Transparent). Frame sizes up to 32 Kbytes are supported in HDLC mode to allow support for a wide variety of specialist synchronous protocols. The transparent bitstream is suitable for transparent data requirements such as Audio, MPEG Video, DAB and DRM. The asynchronous functions are not available from the Linux API.

The source for the application and drivers is included, with the Linux API manual provided in pdf format. The driver is supported under kernel version 2.4 and 2.6 for both single CPU and SMP 32 and 64 bit machines. Typically 12 or more cards (48+ ports) can be supported on a single Server; the card limit is only dependent on the PCI slots resources available in the Server, the maximum within Linux is 32. For further information on the API see the Linux HDLC / Transparent API Manual (pdf).

Embedded Development

The card is supplied with a comprehensive suite of software to keep your development timescales and costs to a minimum. This includes an executive, communications drivers, sample on board application, code downloader for Windows and DOS, code relocator, event log viewer and card test program utilities.

Executive

An executive is supplied with the card, it is written in Assembler requiring no more than 4 Kbytes at run time. The executive provides the following features: CPU initialisation, interrupt vector control, memory allocation control, an event log (accessible from the PC), illegal instruction notification, undefined interrupt handling, PC controlled embedded application initiation and status notification. For configurations using a small shared memory window an executive provides an application bootstrap loader. The source code may be modified or adapted for use on the FarSync adapters on a royalty free basis.

HDLC Drivers

Drivers for the HDLC controllers are provided. The code which is written in C utilises the SDMA (Smart DMA) linked buffer list system feature of the Am186CC. The source code may be modified or adapted for use on the FarSync card on a royalty free basis.

Sample Application

A simple to follow sample embedded application written in C is included. The application which can easily be modified uses the HDLC drivers to transmit and receive frames between ports whilst also driving the LEDs and providing status information to the event log.
