Black Box serial adapter - 62 ports

When you need to add one, two, or four serial PCI ports to your personal computer, select a PCI Card from Black Box. All of the cards feature 16850 buffered UARTs for speeds up to 460.8 kbps. The cards are designed to maximize DOS, Linux, OS/2, QNX, Windows 3.1x/95/98, Windows NT, Windows Me, Windows 2000, Windows XP, and UNIX communications. Windows drivers, utilities, INF files, and help files are included to simplify installation. The IC187C-LP features a pair of field-selectable RS-232/422/485 serial ports. Configure both ports as RS-232 when highly reliable standard serial ports are required. Choose RS-422/RS-485 mode for long-distance device connections up to 4000 ft. (1219.2 m) where noise immunity and high data integrity are essential. Like the IC973C, up to 31 RS-485 devices can be connected to each port to automate your data collection. You can even mix the ports in any of the interface combinations to suit your application.
