  • The Fastcom PCIe Bus, Asynchronous RS422/485 adapter utilizes the latest technology to live up to today's requirements for high bandwidth in communication systems. The Fastcom: 422/4-PCIe is capable of operating at virtually any baud rate up to an astounding maximum serial data rate of 6.25 Mbps. There is no fine print or asterisks pointing to notes; this card is capable of running at the maximum data rate, without any jumpers or hardware changes, right out of the box.

    The Fastcom: 422/4-PCIe adapter utilizes an advanced quad Universal Asynchronous Receiver and Transmitter (UART). Each channel of the 17V354 UART is independently controlled and has its own 16C550 compatible register set. Each UART contains its own receive and transmit FIFO's of 256 bytes, each with programmable trigger levels.

    Each of the four UART channels on the board can be independently configured as either RS-422 or RS-485 for full or half-duplex communication. Additionally, each board utilizes a programmable clock generator to create the UART's input frequency. The clock generator is capable of generating frequencies between 6 and 50 MHz. Utilizing this feature, it is possible to configure the board to operate at virtually any non-standard serial data rate that the user desires (up to 6.25 Mbps maximum).
