Sealevel Systems has released a new PCI serial interface that offers eight field-selectable RS-232/422/485 asynchronous serial ports. The 7804c supports data rates exceeding 1 Mbps and is designed for industrial robotics applications.

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 RS-485 can be implemented for applications that capture data from multiple peripherals along a network.

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.

Features of the 7804c PCI Serial Interface include:

  • Eight serial ports, individually configurable for RS-232, RS-422, or RS-485
  • Ultra high-speed UART with 256-byte Tx and Rx FIFOs
  • Support for asynchronous data rates exceeding 1 Mbps
  • Bus-derived 125 MHz BRG and clock prescaler support wide range of baud rates
  • All modem control signals implemented in RS-232 mode
  • Automatic RS-485 enable/disable in hardware
  • 0°C to 70°C operating temperature range

Earle Foster, Sr VP of Sales for Sealevel, commented: “Sealevel’s foundation is in I/O. As we’ve expanded product line to include embedded computers and carrier boards, we’ve never faltered in the pursuit of providing high-reliability I/O for our customers. The 7804c is a continuation of that commitment for our PCI serial solutions.”
