The PCA-6187 uses Intel's 865G chipset to support Intel's Socket 478 Pentium 4 and Celeron processor with 800/533/400 MHz front side bus. The dual channel DDR 400 SDRAM interface provides bottle neck free memory bandwidth up to 6.4GB/s. In addition to the two EIDE interfaces (up to four devices), it features a high performance serial ATA interface (up to 150MB/s) which eases cabling to hard drives in industrial chassis with thin and long cables. Other features include chipset built-in high performance VGA interface, dual Giga-bit Ethernet ports, dual channel Ultra 160 SCSI interface, six USB 2.0 ports (up to 480 Mbps), and other standard PC functions like two RS-232 serial ports, one enhanced parallel port and floppy disk interface.
