Introduction

Quatech RS-232 PCI boards utilize a single PCI slot to provide two, four, or eight independent asynchronous serial ports that share a single interrupt. All PCI registers are properly implemented, so you can be assured that Quatech boards will be good citizens on the PCI bus. Serial port connections are made via DB-9 male connectors, DB-25 male connectors, RJ-11 modular connectors (8 port only) or using a breakout box providing one DB-25 male and seven DB-9 male connectors (8 port only).

The boards are implemented with 16750 UARTs containing 64-byte FIFOs. They use a clock multiplying feature allowing the to achieve data rates as high as 921.6 kbps. To maintain maximum signal integrity, Quatech uses a four-layer board design. But, for even more protection in industrial environments, an optional surge suppression package is available. This "IND" option applies a surge suppressor to each line that is capable of sustaining up to 40A peak, 8 x 20µs transient surges, a clamping voltage of 30V and a peak energy dissipation of 0.1 Joules. (Note that implementing the IND option restricts the board's speed to 115.2 kbps).

COM port allocation:

Windows 95/98/Me: For these versions of Windows, Windows will allocate the board a COM port starting at the next free COM port at COM5 or higher - note that this is a 'feature' of Windows 95/98/Me and not a limitation of the Quatech cards. However, it is easy to change the COM port allocation (i.e. to use COM1 -4 or other ones), refer to this document for further details.

Windows 2000/XP: The cards will always takes the next available com port number. Note that if some other installed hardware has been installed and has not removed/uninstalled it but just been unplugged, Windows will reserve that COM port for that device and the Quatech device will take the next free COM port number(s).
