The 7402 PCI interface provides four serial ports, each individually configurable for RS-422 or RS-485. The board is capable of data rates to 460.8K bps and automatically handles RS-485 transmitter enable/disable. The 7402 utilizes 16C850 UARTs that provide 128-byte Tx/Rx FIFOs and ships with a 36 inch cable that terminates to four DB-9M connectors.
