Universal PCI Board Tutorial
Moxa’s Universal PCI Series meets the new slot
standard for expansion boards that is being rapidly
adopted by PC server manufacturers. In addition,
Moxa’s universal PCI boards work with both 3.3-
volt and 5-volt PCI slots, allowing the boards to
be used in virtually any PC available. We provide
2/4/8 independent RS-232/422/485 serial ports for
connecting data acquisition equipment and many
other serial devices to PCs.
Universal PCI
The somewhat old fashioned PCI bus standard
only supports a 32-bit bus and 5V connector
key. However, the trend of sharing maximum
bandwith, reducing power consumption, and
speeding up transmission speed has motivated
• Supports both 64-bit & 32-bit
PCI bus
• Supports both 3.3V & 5V
connector keys
moving the PCI bus standard from 32-bit PCI/5V
to 64-bit PCI/3.3V. Moxa’s universal PCI series
provides the following features, making it easy to
use MOXA boards in any signaling environment.
