FarSync T4E and T4E+ PCI/PCI-X Sync/Async/Clock Communications Network Adapters 4 Port

PCI Synchronous Communications More Like This The FarSync T4E card and software is designed to provide high performance hardware communications solutions for business, government and military requirements who need a Universal PCI synchronous communications card with externally sourced line clocks or highly adaptable control of line clocks. 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 T4E is a Universal PCI communications card (PCI and PCI-X compatible) with four independently configurable sync/async serial ports with and external synchronisation capability (eg sourced from GPS). Sync operation supports transparent bitstream and bitsync (HDLC) of up to 10 Mbits/s per line with a total card bandwidth of 60 Mbits/s. The highly flexible universal network connector supports RS232C, X.21, RS530 (RS422 signaling), RS449 (RS422 signaling) and V.35 network interfaces. The transparent bitstream option available with the APIs is suitable for VoIP (as a subsystem), video and voice such as T-DMB (Digital Multimedia Broadcasting), DAB (Digital Audio Broadcasting) ETI (Ensemble Transport Interface - ETSI EN 300 797).

Linux: The low level API is based on the raw socket interface and supports bit synchronous (HDLC) framed and transparent bitstream data. The T4E card can also use the TCP/IP stack to allow access to IP based networks such as the Internet. It also allows selection of the full range of clock modes. The T4E card installs seamlessly as a plug and play device under the popular Linux 32 and 64 bit distributions. The cards supports Linux kernel version 2.4 and 2.6 in 32 and 64 bit formats, including the leading distributions supplied by Redhat, SuSE, Mandriva, Debian, Ubuntu, Fedora, Slackware and more. Multi-processor systems are supported. FarSite is committed to supporting the FarSync T4E 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. Windows: The products include support for the Microsoft standard Windows SDCI API, providing applications with direct access to the card's communications port/s for bit synchronous (HDLC) framing, asynchronous and transparent bitstream operation for video and voice type applications. The card installs seamlessly under Windows XP, Windows Server 2003, Vista and Windows Server 2008 on both 32 and 64 bit, single and multi-core systems. The FarSync drivers are signed by Microsoft for easy installation. The low level API is based on an extended SDCI interface and supports bit synchronous (HDLC) framed, transparent bit stream data. The special clocking features are all accessible though the SDCI interface. Async support is also provided by the Win32 COMM interface as well as the SDCI IOCTLs. The FarSync T4E can also be installed to appear as a NDIS (LAN) interface so it can simply use the TCP/IP stack to allow access to IP based networks such as the Internet.

T4E+ extra features
  • Manchester encoding is supporting up to 10 MBits/s where the clock for the data is taken from the incoming data line. This means separate clock lines are not required. Manchester encoding is a soft configurable alternative to NRZ. Line termination is supported on all the balanced pair signals for X.21 (V.11), V.35, RS530 (EIA530, RS422) and RS449 (RS422 signalling) operation. The line termination resistors may be soft selected to be selected or deselected on a port by port basis. The addition of line termination resistors can be helpful in improving signal quality on long high speed lines. See this item's Product Page for more information.
