RS-422/485 Synchronous Serial

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-422/485 synchronous serial PCMCIA card 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 that support interrupt-driven
communications with data rates up to 2.45 Mbps. If a specific frequency is required, upgraded crystals
and custom configuration can be provided for speeds up to 4 Mbps.
In addition to super-fast data rates, the card's Syncronous Communications Controller provides 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 and OS/2.
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.
This card is available with a convenient detachable cable.

- SyncDrive (Plus) is a frame-level synchronous communication driver implemented by a DLL and a device driver.
-
Applications interface to SyncDrive (Plus) through C callable routines and C data structures. The routines provide
services for channel configuration, transmitting a buffer, receiving a buffer, setting and monitoring I/O status.

-
Once a handle is opened to the device driver, the application simply reads and writes frames as it would files, without
worrying about buffer management, interrupts, or register handling. SyncDrive (Plus) handles start and end flags, synchronization
characters, and CRC information on transmit and receive. The C data structures used are for configuration, transmitting and receiving buffers.
