Overview

The FarSync T4Ue card and software is designed to provide high performance hardware communications solutions for business, government and the military who need a PCIe synchronous communications card. The product includes a low level driver that allows access to the communications features available in the hardware. The FarSync SDK provides a Developers Toolkit for the product.

The card will support a synchronous line at speeds of up to 10Mbits/s continuous. The highly flexible universal network connector supports RS232, X.21, RS530 (RS422 signalling), RS449 and V.35 network interfaces.

The card is also available with soft selectable asynchronous/synchronous support as well by ordering the FarSync T4Ue+Async model and a PCI version of the adapter, the FarSync T4U is available too.

The products are supplied with a 5 year warranty.



Product details

Both PCIe and PCI 4 port cards comprise an AMD processor with SRAM. The whole memory space may be mapped via the PCIe interface to the PC/Server. The card has a quad embedded HDLC / transparent controller with SDMA access (128 buffers per port) and a full range of timers. Total bandwidth supported by the card is 64 Mbits/s.

Network Interfaces

The multi function line drivers available on all the ports support X.21 (V.11), V.35, RS232 (V.24, X.21bis), RS530 (EIA530, RS422) and RS449 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 adapter support card generated clocks at a wide 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 all ports is individually selectable.

Multiple Cards

The drivers supplied with Windows and Linux allow large numbers of ports to be supported by the installation of multiple FarSync cards in a Server. Typically 12 or more cards (24+ ports) can be supported; the card limit is only dependent on the resources available in the host Server and the total bandwidth of the PCIe/PCI/PMC bus.

PCI Express Bus Specification

FarSync PCIe cards are suitable for systems with a PCIe bus, covering single and multi-processor systems. These cards are compliant with PCI Express Base specification revision 1.0a and above. The FarSync adapters are bus mastering, 1x (single lane) cards.

FarSync PCI cards comply with the Universal PCI (PCI-X compatible, PCI v2.2 compliant) specification. These bus mastering cards are suitable for systems with a PCI bus, covering single and multi-processor systems.
