The TITAN uPCI-400L,uPCI-400LS and uPCI-400LP Universal PCI serial I/O cards offers four independent RS-232 serial ports. This I/O board supports both 3.3V and 5V PCI bus, and it’s compatible with 32-bit PCI, 64-bit PCI and PCI-X bus. All serial ports are built by 16550A-compatible UARTS with 16 byte FIFO.

The TITAN uPCI-400L,uPCI-400LS and uPCI-400LP Universal PCI serial I/O cards provide connectivity to RS-232 communication devices for factory automation equipment, multi-drop data collection devices, barcode readers, time clocks, scales, data entry terminals, PC to PC communications and serial communication in harsh environments.

The supplied drivers for Windows operating system install the serial ports into the Windows API, so they appear as the usual Com ports software requires. A rich set of driver options is configured via the Device Manager in Windows. The drivers allows to configure the serial ports for a bit-rate of up to 921,600 bps.

The uPCI-400L,uPCI-400LS and uPCI-400LP Universal PCI serial I/O card is an advanced and high efficient solution for serial data communication and industrial automation applications.
