RCSC-PCIe Synchronous PCIe Serial Card / DATA X2

The RapidM Synchronous Serial Card (RCSC-PCIe) is a PC-based interface card designed to support the NATO defence communications protocols STANAG 5066 and STANAG 4691 requiring synchronous serial communication interfaces. The RCSC-PCIe is a dual-port data communication equipment (DCE) device based on the PCI Express (PCIe) expansion bus standard.

The RCSC-PCIe provides high-speed asynchronous and synchronous serial communication interfaces. Two RS-232 serial ports capable of data rates up to 384 kbps for synchronous and 460.8 kbps for asynchronous. The card is based on Altera FPGA technology for maximum reliability in data intensive applications. The RCSC-PCIe software driver and utilities make installation and operation easy using Microsoft Windows or Linux operating systems.
