OMG-ULTRACOMM422-PCI from $379
Automatic Four Port PCI RS-485/422 Interface for DOS and Windows 3.1x/95/NT

Automatic Four Port PCI RS-485/422 Interface

The OMG-ULTRACOMM422-PCI provides four PCI bus RS-485/422 Async links for data collection and other devices. In RS-485 mode, our auto enable feature enables the RS-485 line driver during character transmission and disables it afterward allowing the standard COM: driver to be utilized. The onboard interrupt status port provides maximum Windows flexibility. The OMG-ULTRACOMM422-PCI includes the 16550 UART, providing a 16 byte FIFO to keep your datacom applications running error free. Windows 3.1x drivers are available for more than 4 COM: ports. Windows 95 automatically configures the OMG-ULTRACOMM422-PCI, therefore drivers are not required. Drivers are provided for Windows NT.

A serial utility diskette is included which includes all the Windows and DOS tools necessary to verify the installation and operation of the board. Windows utilities include .INF files for Windows installation and also a Windows NT COM: Port Installation Utility. DOS utilities include a diagnostic program to verify card address and examine the UART, a diagnostic serial loopback test program and an interrupt driven DOS serial port driver.
