The Sealevel Systems ULTRA COMM+422 provides the PC with four RS-422/485 Asynchronous links to data collection and other devices. Individually selectable addresses and extended “AT” interrupts allow for seamless integration. The ULTRA COMM+422 appears to the host system as a standard COM: port, requiring no special drivers or additional software. We include our Advanced COM drivers for Windows 95/98/ME/NT/2000 and XP providing IRQ sharing, Windows serial diagnostics, and other enhanced features. Our Linux and QNX utilities are also included to simplify installation.
