The FarSync T2Ue PCIe card provides a very flexible 2 port PCI Express sync communications
platform for Linux and Windows systems
Overview
The FarSync T2Ue card and software is designed to provide high performance hardware communications solutions for business, government and the military who need a PCI Express synchronous communications card. The product includes a low level driver that allows access to the communications features available in the hardware. The card can optionally use the host’s standard TCP/IP protocol stack to allow access to IP based networks such as the Internet.
The FarSync SDK provides a Developers Toolkit for the product. The FarSync T2Ue card is functionally compatible with the Universal PCI based FarSync T2U card.
The card will support a synchronous line at
speeds of up to 10Mbits/s continuous. The highly flexible PCI Express network connector supports RS232, X.21, RS530 (RS422 signalling), RS449 and V.35 network interfaces.
The product is supplied with a 5 year warranty.
Features under Windows:
The Windows based API common to the entire range of FarSync cards/devices is referred to as the FarSync Windows API (FsWinAPI). This is an extension of the MS COMM API and enables, for example, applications developed to support COM ports, to be easily ported to use FarSync support in synchronous modes. This standardization enables the API to also be readily accessible from higher level environments such as .NET, C#, VB etc.
The FsWinAPI provides applications with direct access to the card’s communications port/s for bit sync (HDLC) framing and also transparent bitstream operation for video and voice type applications.
The FarSync T2Ue can also be installed to appear as a NDIS (LAN) interface so it can simply use the TCP/IP stack over PPP to allow access to IP based networks such as the Internet.
The card installs seamlessly under Windows 10, 8, 7, Vista, Windows Server 2016, 2012 and 2008 on both 32 and 64 bit, single and multi-core systems. The FarSync drivers are signed by Microsoft for easy installation.
LabVIEW applications can access this adapter.
Features under Linux:
The API is based on the Char I/O interface and supports bit synchronous (HDLC) framed and transparent bitstream data. The T2Ue card can also use the TCP/IP stack to allow access to IP based networks such as the Internet.
The T2Ue card installs seamlessly as a plug and play device under the popular Linux 32 and 64 bit distributions. The cards supports Linux kernel versions 2.6.12 onwards in 32 and 64 bit formats, including the leading distributions supplied by Red Hat, SuSE, CentOS, Ubuntu, Debian, Fedora, Slackware and more. Multi-processor
systems are supported.
FarSite is committed to supporting the FarSync T2Ue on new versions of Linux and Linux kernels as they are released. The
source code for the driver is supplied
with the product allowing rebuilding by the end user for use with
almost any of the current or future Linux variants. The driver supports both big-endian and little-endian memory storage formats.
Developers Toolkit:
The FarSync SDK provides a Developers Toolkit with full documentation, useful utilities, such as a line monitor, and many sample applications for Linux and Windows. Free support from FarSite’s Engineering department is provided to customers purchasing the FarSync SDK who have technical questions using the API.
Typical

- 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
- Internet Access and remote office access over leased lines
- HDLC framing support for non standard or specialist protocols
FarSync T2Ue – Product Details
The FarSync T2Ue is supplied with software drivers for Windows and Linux. This includes a low level driver that allows access to the communications features available in the hardware and an optionally installable driver that connects with the standard TCP/IP protocol stack to allow access to IP based networks such as the Internet.
The drivers supplied with Windows and Linux allow large numbers of ports to be supported by the installation of multiple FarSync T2Ue cards in a Server. Typically 12 or more cards can be supported; the card limit is only dependent on the PCI Express slot count and resources available in the host Server and the total bandwidth of the PCIe bus.
Card Hardware
The 2 port card runs an AMD processor with SRAM. The card has a dual embedded HDLC / transparent controller with SDMA access (128 buffers per port) and a wide range of timers. Total bandwidth supported by the card is 40 Mbits/s.
Network Interfaces
The multi function line drivers available on both ports support X.21
(V.11), V.35, RS232
(V.24, X.21bis), RS530
(EIA530, RS422), RS449 (RS422), network interfaces, all soft configurable and ESD protected from static charges. The maximum supported line speed is 10 Mbits/s full duplex.Clock Generation
As well as external clocking the T2Ue supports card generated clocks at a range of standard frequencies from 9,600 baud to 8.192 Mbits/s and dual clocks can be generated in V.11 mode if required. The clocking speed of both ports is individually selectable.
PCI Express Bus Specification
The FarSync T2Ue complies with the PCI Express Base Specification Revision 1.0a
Key Features supported on Linux
The Char I/O API provides a programming language independent, high-level interface to the FarSync base driver it supports access to all the cards modes of operation. The cards can also use the TCP/IP stack to allow access to IP based networks such as the Internet.
The T2Ue card installs seamlessly as a plug and play device under the popular Linux 32 and 64 bit distributions.

The FarSync T2Ue installs easily under Windows 10, 8, 7, Vista, Windows Server 2016, 2012 and 2008 on single or multi-core 32 and 64 bit systems. A FsWinAPI driver is installed with the optional installation of an NDIS (LAN) driver. The NDIS driver supports TCP/IP running over PPP with optional authentication by CHAP or PAP (RFC 1334) providing a standard point-to-point network interface. The drivers are signed by Microsoft for easy installation. Applications running in LabVIEW can access the card.
The product is supplied with a comprehensive configuration utility and its own Line Monitor that allows the user to record, display and store line traffic with WAN protocol decoding for fast debugging.
The FarSync T2Ue FsWinAPI allows applications developed using the FarSync SDK to exactly control the type of data sent and received in bit synchronous (HDLC framed) data and transparent bitstream formats in NRZ signal mode.
FarSync SDK – The Developers Toolkit
The SDK includes support for writing applications on both Linux and Windows and contains documentation, working sample applications, development and test utility applications. There is everything a user needs to rapidly develop and test a wide variety of applications such as specialist synchronous (HDLC framed) protocols or transparent bitstream data requirements including Audio, MPEG Video T-DMB and DAB ETI with bitstream encoder and decoder. The FarSync SDK is ordered separately from the FarSync T2Ue.
Our Engineering department provides free email and telephone assistance to application developers using the API as part of the package provided when the FarSync SDK is purchased.
