SuperFastcom/2-104-ET Industrial Temperature Synchronous RS422 & RS485 PC104+ Bus Serial Communications Interface Adapter

The SuperFASTCOM/2-104-ET adapter is a very high speed, dual channel, synchronous serial communications adapter designed for use in Windows and Linux based industrial/commercial systems. Its outstanding features include data rates up to 10 Mbits/s¹ and the ability to buffer up to 4 Gigabytes of data (Windows 2000) in system memory. The SuperFASTCOM/2-104-ET adapter is designed for industrial applications requiring rugged construction, high reliability and full industrial temperature tolerance (-40 C to +85 C). The interfacing connector is a 2x20 right angle header connector with ejector latches.

The SuperFASTCOM/2-104-ET supports all standard synchronous protocols (HDLC, SDLC) and their variations as well as all standard asynchronous data formats at data rates up to 10 Mbits/s¹. The external on-board clock generator provides a high-speed clock source for your system and eliminates the need for an external clock. The board also features high-speed RS422 / RS485 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. Software drivers are included for Windows 2000, XP, 2003, and Linux kernels 2.4 and 2.6. The SuperFASTCOM/2-104-ET provides high speed and high reliability while greatly reducing development time and system complexity.

The following diagram illustrates the basic structure of the SuperFASTCOM/2-104-ET:

The SuperFASTCOM family of adapters also includes RS422/485 and RS232 PCI, cPCI, and cPCI Rear I/O Bus Styles.

¹Data rates are limited by factors such as cable length, cable quality, and the type of linear drivers and receivers used.
² According to section 3.1.3 of the PEB20534 Errata Sheet (DS7 2003-07-31): DPLL clock recovery is non-functioning when recovering from an FM0 (Bi-Phase Space), FM1 (Bi-Phase Mark) or Manchester (Bi-Phase) encoded receive data stream. If using NRZ (Non-Return-To-Zero) or NRZI (Non-Return-To-Zero-Inverted) line encoding, DPLL clock recovery will function properly.
