Antaira MSC-202A1 PCI Express Card with 2 Ports of RS-232 and Oxford Single-Chip PCIe

The MSC-202A1, from Antaira Technologies, is an RS-232 PCI Express card that adds 2 ports of serial communication to industrial computers, rack mount servers and desktops.  It may function as a client or server to connect older serial based equipment like point-of-sale terminals, scanners, card readers and instruments. It has two male DB-9 front panel connectors with pins to supply 5V and 12V power. 

The MSC-202A1 features the Oxford Semiconductor single-chip PCIe interface which offers increased throughput and low CPU utilization.  It’s ideal for demanding communication applications requiring high-level system performance.
