The 7204 PCI serial interface provides two 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 7204 utilizes 16C850 UARTs that provide 128-byte Tx/Rx FIFOs. Ordering options allow the choice of UARTs with support for custom baud rates and 9-bit protocols. Sealevel's SeaCOM software utilities make installation and operation easy.
