The 7804c PCI Serial Interface with eight field-selectable RS-232/422/485 asynchronous serial ports

The range of configurability enabled by the 7804c PCI Serial Interface allows users to implement for standard serial COM port requirements via RS-232. RS-422 mode can be used for long distance device connections, or for applications where noise immunity and high data integrity are essential. And for applications that capture data from multiple peripherals along a network, RS-485 can be implemented. Flexibility is maximized as the ports can be assigned a variety of electrical interface combinations while relying on a single 7804c. For use in extreme environments, the 7804c features a wide operating temperature range of 0°C to 70°C. Sealevel's SeaCOM software is included for easy installation and operation.
