5V PCI 4 Port RS422/485 Opto Isolated
This half size card provides four serial ports independently configurable as RS422 with and without hand-shaking, or RS485 full or half duplex, with opto isolation on all RS422/485 lines. The card has on-board zener diodes giving transient spike protection to the inputs, making these cards ideal for factory automation installations. The megabaud data transfer rates and the 64 byte deep FIFO, coupled with the RS485 Half Duplex Autogating guarantees uncompromising performance and fault-free use. The PCI RS422/485 Velocity card uses the 16750 UART, two generations beyond the industry standard 16550. The UART clock can be set through software to provide maximum baud rates of either 921,600 baud, 460,800 baud, 230,400 baud, or 115,200 baud (standard PC). Serial Solutions Device Driver CD contains software for Windows 7, Server 2008, Vista, Server 2003, XP, 2000, Millennium, 98, 95, NT4, Windows 3.x, DOS and OS/2. Informative manuals and sample programs are supplied with full source code on CD!
