THIS ITEM IS BUILD TO ORDER. PLEASE CONTACT YOUR SALES REPRESENTATIVE FOR MORE INFORMATION.
The 7903 is a 3U Compact PCI interface adapter with two isolated serial I/O ports. It provides two field selectable RS-232, RS-422, or RS-485 serial ports supporting data rates up to 921.6K bps. Isolation is important in installations where the equipment connected to the PC is either located far from the host system, or on a different power transformer circuit.
For user's that require custom baud rates, isochronous communications, or 9-bit protocol, the 7903 compact PCI serial interface is available with the Oxford 16C950 UART. Call for details.
