2.5.4 Serial Port connector: COM1/COM2

COM1, COM2 are use in the 10-pins box-header, are onboard serial ports of the CPU card SYS7180VE. The following table shows the pin assignments of these connectors.

The parallel port bracket can used to add an additional parallel port for additional parallel devices. There are four options for parallel port operation:

Compatible (Standard mode) Bi-Directional (PS/2 compatible)

Bi-Directional EPP. A driver from the peripheral manufacturer is required for operation.

Bi-Directional High-speed ECP

2.5.5 IDE port Connector: IDE1/ IDE2

The CPU card SYS7180VE provides a bus-mastering PCI IDE interfaces. These interfaces support PIO Mode 3, PIO Mode 4, ATAPI devices (e.g., CD-ROM), and Ultra DMA/33/66/100 synchronous-DMA mode transfers. The BIOS supports logical block addressing (LBA) and extended cylinder head sector (ECHS) translation modes. The BIOS automatically detects the IDE device transfer rate and translation mode.

Programmed I/O operations usually require a substantial amount of processor bandwidth. However, in multitasking operating systems, the bandwidth freed by bus mastering IDE can be devoted to other tasks while disk transfers are occurring.
