    Designed to comply with the latest PCI specifications, the Fastcom: GFSCC/4 Universal PCI (PCI version 2.3) adapter will operate in both 5V and 3.3V PCI slots. This means the card will work in the high speed PCI-X slots commonly found in most new servers, as well as the standard PCI slots in desktop PC’s. This flexibility allows for a single serial interface board to be used across a wide range of different types of computers including both current and future computing systems. The Fastcom: GFSCC/4 adapter is the one of the most advanced synchronous communications adapters in the industry. The Fastcom: GFSCC/4 supports data rates up to 20 Mbit/s¹. The Fastcom: GFSCC/4 is a four channel adapter, with each one being individually configurable to use HDLC/SDLC, ASYNC (using FC950 UARTS), or Fastcom®: X-Sync protocols. Although similar to the ESCC and SuperFastcom families of adapters, the GFSCC/4 expands on our previous adapters. The most notable expansion is the longevity of the components of the board. Faced with the inevitability of obsolescence, Commtech decided to put an end to the lifespan problems that plague most computing customers. We designed a serial communications controller with our customers’ needs in mind, and built a card around it. Wholly designed and owned by Commtech, Inc, this FPGA based SCC has most of the features that you are used to seeing in a quality Fastcom product. It also includes a few new features that come directly from customer requests. If the existing FPGA technology is ever discontinued by the chip manufacturer, the design can simply be re-targeted to the next generation of FPGA chip with no impact on compatibility.

    Difference Between Fastcom: GFSCC/4 and Fastcom: GSuperFSCC/4

    The GSuperFSCC/4 card features bus-mastering DMA; therefore, it greatly decreases the amount of interrupts that must be serviced by the host CPU, thus freeing it up for other activities. By utilizing this DMA, the GSuperFSCC/4 is able to stream gapless, full duplex data at the full 50 Mbit/s1. The standard GFSCC/4 card is only able to perform the same task at around 20 Mbit/s. The standard card is capable of operating at rates up to 50 Mbit/s with data bursts. It cannot sustain higher rates without generating gaps in the data (e.g. idle between frames).

    1This is possible as long as the operating parameters are within reason. For instance, you cannot expect to perform continuous, full duplex operation at 50 Mbit/s with 2 byte frames. This will require reasonable sized frames with a minimum size of around 1024 bytes. If you have any question about whether the card can meet your needs, please contact Technical Support.

        • HDLC/SDLC
          • The GFSCC and GSuperFSCC families of cards fully supports the HDLC framing convention. It does not support automatically decoding of the SDLC control fields. If control bytes are present in received frames they will be passed to the user as if they were part of the info field. If control bytes are required to be transmitted they will have to be generated by the user and written as if they were data.
