Introduction
The above I/O cards are isolated up-to 5000 Vdc (excluding cables) for
channel-to-computer isolation. It protects your computer against damage
caused by accidental contact with high external voltage and eliminates
troublesome ground loops.
The 743X series products use PCI-9050 PCI controller to interface the board
to the PCI bus. The PCI-9050 fully implements the PCI local bus
specification Rev 2.1. All bus relative configurations, such as base memory
and interrupt assignment, are automatically controlled by BIOS software.
1.1 Features
The PCI-743X Isolated D/I cards provide the following advanced features:

*1: For PCI-7433, cPCI-7433R and cPCI-7432R/P, the isolation
voltage is up to 2500 Vrms.
