The FarSync T2U-PMC cards provide a very flexible 2 port sync communications PMC platform for Linux and Windows systems.
The FarSync T2U-PMC adapters offer a high quality PCI Mezzanine adapter solution for business,
government and military applications. They have been developed to provide high performance,
versatile synchronous connectivity for Linux and Windows systems using industrial quality components
providing wide temperature range operation.
The products include low level drivers that allows access to the communications features available in
the hardware. The adapter 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
The PMC adapters will support 2 synchronous ports at speeds of up to 10 Mbits/s. Two versions of the
adapter are available – the FarSync T2U-PMC-R supporting rear I/O and the FarSync T2U-PMC-F
supporting both rear and front I/O. Both the front and rear I/O connectors can support RS232, X.21, RS530 (RS422 signalling), RS449 and V.35 network interfaces.
Adapter carriers allow PMC cards to work in a cPCI or a VME based chassis.
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 T2U-PMC cards can also be installed to appear as a NDIS (LAN) interface so they 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 these cards.
Features under 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 T2U-PMC cards install seamlessly as a plug and play device under the popular Linux 32 and 64 bit distributions. The cards supports Linux kernel versions from 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.
Big Endian and Little Endian drivers are supplied.
FarSite is committed to supporting the FarSync T2U-PMC 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.

- HDLC framing support for non standard or specialist protocols
FarSync T2U-PMC – Hardware Details
The adapter comprises an AMD processor with no wait state SRAM. The whole memory space may be mapped via the PMC interface to the PC/Server. The AMD processor contains a dual embedded HDLC / transparent controller with SDMA access (128 buffers per port) and a full range of timers.
The drivers supplied with Windows and Linux allow large numbers of ports to be supported by the installation of multiple FarSync T2U-PMC cards in a Server. Typically 12 or more cards can be supported; the card limit is only dependent on the number of available PMC sites, resources available in the host Server and the total bandwidth of the PCI bus.
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 2 synchronous ports which can run to speeds of up to 10 Mbits/s full duplex internally clocked and 10 Mbits/s externally clocked. Total bandwidth supported by the adapter is 40 Mbits/s. Line termination resistors are software selectable.
Terminal Timing is supported on the network interfaces to enable system-wide clock synchronisation.
Internally generated clocks to drive a serial communications port can be derived from an on-board 8.192MHz clock (25ppm) and can be set to hundreds of different frequencies between 100 baud and 10 Mbits/s, 160 are preset, many other frequencies can be synthesized to order, contact us to discuss your requirements.
The FarSync T2U-PMC (PCI Mezzanine card) cards are suitable for systems with a PMC connector, covering
single processor and multi-processor systems. The adapter is 33/66Mhz PCI bus revision 2.2 compliant with
support for both 3.3 and 5 volt signalling, the power for the adapter is taken from the 3.3 volt supply rail.
Cables can be supplied to connect to the Front I/O connector (FarSync T2U-PMC-F) to support RS232, X.21,
RS422, RS530, RS449 and V.35 connections, see the order information for details on the last page.
Cables are not supplied for the Rear I/O only version (FarSync T2U-PMC-R), full connection details on the IEEE 1386 connector for operation with RS232, X.21, RS422, RS530, RS449 and V.35 are supplied.
For Windows configuration is by a GUI application, a typical screen is shown on the right.
The line can be reconfigured and restarted without reloading the software.
There is context sensitive help and an on-line manual should it be required. An advanced tab permits users to further specify the configuration
of the line if necessary.
For Linux a configuration utility is provided; alternatively text files can be used.
