2 Module Description
2.1 OXPCIe958
The device combines a fully integrated, single-lane PCI Express end-point controller and SerDes with eight
high-performance 950 UART.
The OXPCIe958 achieves outstanding performance including 128 byte transmit and receive FIFOs of the 950
UART, with advanced system management features such as MSI/MSI-X interrupt handling and bus master DMA
to maximize data throughput while substantially reducing CPU and system overheads. Each 950 UART has full
modem interface and includes advanced features such as hardware-accelerated out-of-band and in-band flow
control, readable FIFO levels and RS485 turnaround delay for further performance optimization, while the
flexible clock prescaler provides scope for the widest-possible range of baud rates.
Serial Ports
Four serial ports are conducted to DSUB-9 connectors at the front side. The other four serial ports are available
on IDC10 pin headers which can be used with the help of adapter cables provided by Lippert. All ports can
either work in RS232 or in RS485 mode. That mode can be switched with jumpers at runtime, the location can
be found in chapter jumper.
