• 5I21  FPGA based PCI  RS-422/RS-485 I/O card

The MESA 5I21 is a programmable serial interface card for the PCI bus. The 5I21 is designed for applications using RS-422 and RS-485 interfaces. The 5I21 can support up to 12 full duplex RS-422 or half duplex RS-485 serial links with baud rates up to 10 M baud. The 5I21 uses a 400K gate Spartan3 FPGA and a bus mastering PCI bridge for high performance. Since all serial logic is FPGA based, almost any RS-422/RS485 protocol can be supported. The I/O connector is a 68 pin high density type compatible with standard 100 ohm differential cables. On card serial line termination includes idle line pullups and pulldowns to guarantee a valid undriven input state. The 5I21 is suitable for high speed motion control systems, Industrial I/O, Custom real time distributed I/O, supporting legacy hardware, and almost any high speed serial interface application that requires a flexible, high performance, universal serial interface card.
