Quatech MPAC-100

Introduction

Synchronous serial connectivity is an appropriate choice when rigorous security and intensive data integrity protocols are required for high-speed serial communication. It is the communication method of choice for a wide variety of military and commercial systems such as satellite monitoring, radar control, GPS systems, flight recorder data transfers, and HF (High Frequency) e-mail systems to name a few.

Quatech's single port RS-232 synchronous serial PCI board supports asynchronous data formats as well as byte-oriented synchronous protocols such as BiSync, and bit-oriented synchronous protocols such as HDLC and SDLC. The card's robust design provides 1024-byte transmit and receive FIFOs, and a SCC with advanced internal functions including on-chip baud rate generators and digital phase-lock loop (DPLL) for recovering data clocking from received data streams.

Quatech's frame-level HDLC and Bisync driver, SyncDrive, is included for Windows 95/98/Me, OS/2 and DOS. For Windows 2000/XP, SyncDrive Plus, a bit-synchronous SDLC/HDLC driver is also included. Both SyncDrive packages are not application programs themselves, but provide C callable routines and C data structures designed to aid users in the development of their own application software.

Most applications written using SYNCDRIVE for Quatech ISA and PCMCIA synchronous communication cards can be easily adapted for the PCI boards. And, using SYNCDRIVE software across multi-platform applications saves time and money because the application and driver software require only minor modifications for each interface choice.
