Features
DescriptionSynchronous 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 communication with data rates up to 2.45 Mbps. If a specific frequency is required, upgraded crystals and custom configurations can be provided for speeds up to 4 Mbps. In addition to super fast data rates, the card's SCC 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. Note: The MPAP-200/300 is a 5V PCMCIA card. Some newer laptops no longer support 5V cards. See this FAQ for a list of models known not to provide this support. The MPAP-200/300 is currently being redesigned for 3.3V operation. Sales Information:
