Brainboxes UC-310B Dual Port Universal PCI Serial Card

Two opto-isolated RS-422/RS-485 serial ports on Brainboxes UC-310B sit on a universal PCI card that plugs into a standard PCI slot, providing rugged, isolated communications for PC-based control and data acquisition. Each port presents a DB9 9-pin male connector and is driven by Brainboxes' 16C958 UART, with backward compatibility to 16750/16550/16450 modes and an enhanced 950 mode. Data throughput reaches up to 921,600 baud per port, backed by 128-byte transmit and 128-byte receive FIFOs and 1 Mbit/s line drivers to sustain bursts. The card supports RS-422/RS-485 signaling on both ports, with transient spike protection and opto isolation on the serial lines for improved noise immunity in demanding environments. Driver support covers Windows 32-bit and 64-bit operating systems, including Windows 8, with Brainboxes providing compatible software for setup alongside standard PCI bus compatibility. This UC-310B variant is part of Brainboxes’ universal PCI range, designed to fit systems that require two independent RS-422/RS-485 channels in a compact, single-card solution.
