| Abstract |
The SIO4-104.485 , Item Number 3543, is a PC/104 module that provides four, RS-422/485 serial
interface ports. The board is designed using the XR16C554 UART, which provides a 16-byte
FIFO. In addition to the standard XR16C554 UART, the XR16C854 (`SE' option) and the OX16C954
(`SN' option) are available. Both UARTS feature enhanced FIFOs (128 byte transmit and
receive) and both maintain compatibility with the XR16C554. The OX16C954 additionally
features a flexible clock prescalar (from 1 to 31.875), 9 bit protocol, and an isochronous mode. RS-422 pr...
