PCIe-S148/VXC-148U

PCIe-S148/VXC-148U

The PCIe-S148/VXC-148U card is the new generation product that ICP DAS provides to meet RoHS compliance requirement. The VXC-148U supports 3.3 V/5 V PCI bus, while the PCIe-S148 supports PCI Express bus.

The PCIe-S148/VXC-148U card provides 8 RS-422/485 serial ports. It is equipped with a 256-byte hardware FIFO for each port, supports for speed up to 115200 bps (VXC-148U) or 921600 bps (PCIe-S148) and supports full-duplex communication. The PCIe-S148/VXC-148U card support drivers choose an available COM port number automatically.

The serial communication card are designed for use with intelligent devices like bar code reader, serial printers, intelligent sensors, instrumentation equipment, computers and almost any device with an RS-422/485 port.
