ABSTRACT:
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 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.
