SuperFastcom 232/4-PCI Cable

DB78 plug to four DB25 plugs (Included)

The SuperFASTCOM: 232/4-PCI PCI adapter is a very high speed, four channel, synchronous serial communications adapter designed for use in Windows and Linux based industrial/commercial systems. Its outstanding features include data rates up to 1 Mbit/s¹ and the ability to buffer up to 4 Gigabytes of data (Windows 2000) in system memory.

The SuperFASTCOM: 232/4-PCI supports all standard synchronous protocols (HDLC, SDLC) and their variations as well as all standard asynchronous data formats at data rates up to 1 Mbit/s¹.

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: 232/4-PCI provides high speed and high reliability while greatly reducing development time and system complexity.

The following diagram illustrates the basic structure of the SuperFASTCOM 232/4-PCI:

The SuperFASTCOM family of adapters also includes RS422/485 PCI, PC/104+, cPCI, and cPCI Rear I/O Bus Styles.

(d) = approximate MAX cable length in feet (bps) = estimated MAX baud rate at given length
d = ( -9.04*10-5 * bps ) + 192

bps = ( -11,000 * d ) + 2.13*105

Equations are based on experiments using Olympic cable number 2829 with 30pf/ft nominal capacitance at a maximum of 83 ft (CL not to exceed 2500 pico farads per EIA-232). These equations are an estimate of the maximum capabilities in users' environment, different cable capacitance will yield different results.
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.
