INTRODUCTION
The new Super FASTCOM PCI adapter is a very high-speed, four channel, synchronous serial
communications adapter designed for Windows- and LINUX-based industrial/commercial
systems. Its outstanding features include data rates up to 40 Mbits/s and the ability to buffer
up to 4 Gigabytes of data (Windows 2000) in system memory.
The
Super FASTCOM supports standard synchronous protocols (HDLC, SDLC) and their
variations, as well as standard asynchronous data formats at data rates up to 40 Mbits/s. The
on-board clock generator provides a high-speed clock source for your system and
eliminating the need for an external clock. The board also features high-speed RS-422/RS-
485 drivers/receivers with on-board line termination.
Programming is simplified with the inclusion of drivers, example programs and comprehensive
documentation supplied on the Fastcom CD. The
Super FASTCOM provides high speed and
high reliability while greatly reducing development time and system complexity.
The
Super FASTCOM family includes:
Form Factor Line Type Ports
PCI RS422/485 OR RS232 4
PC/104+ RS422/485 1 or 2
CompactPCI RS422/485 4
CompactPCI Rear IO RS422/485 4
