Introduction
The PCI-7230 provides 32 isolated digital I/O, 16 Isolated inputs
and 16 isolated outputs. The isolated I/O channels are isolated to
2,500 Vrms (excluding cables), both channel-to-channel and
channel-to-computer. It protects your computer against damage
caused by accidental contact with high external voltage and
elimates troublesome ground loops.
The PCI-7230 uses SAIC PCI controller to interface the board to
the PCI bus. The ASIC fully implement the PCI local bus
specification Rev 2.0. All bus relative configurations, such as
base memory address and interrupt assignment, are
automatically controlled by BIOS software. It does not need any
user interaction and pre-study for the configurations. This
removes the burden of searching for a conflict-free configuration,
which can be very time consuming and difficult with some other
bus standards.
