Introduction
PCI Express
(
Peripheral Component Interconnect Express
), officially abbreviated as
PCIe
(or
PCI-E
, as it is commonly called), is a computer expansion card standard.
The PCI Express serial cards meet the PCIe standard to work with any PCI Express slot.
The boards have multiple RS-232/422/485 serial ports for connecting data acquisition
devices and other serial devices to your computer.
The PCI Express serial cards are compatible with a wide variety of Windows operating
systems, support data transfer rates up to 921.6 Kb/s, and provide full modem control
signals to ensure compatibility with wide range of serial devices. In addition, all models
come with PCI Express x1 bus connector, allowing the boards to be installed in any
available PCI Express slot.
PCI Express Solution
The PCI Express serial cards comply with PCI Express Spec. 1.1. The port transmission
parameters are configured after the board is installed. The PCI BIOS automatically
assigns the IRQ and I/O addresses.
ESD Protection
The PCI Express serial cards come with built-in 15 KV ESD to protect the board and
connected device(s) from unforeseen power surges. The surge protection feature
makes the PCI Express serial cards suitable for industrial, factory-type applications, and
for use with applications that are subjected to severe operating conditions.
Optical Coupler
Opto coupler is "an electronic device designed to transfer electrical signals by utilizing
light waves to provide coupling with electrical isolation between its input and output. The
main purpose of an opto-isolator is "to prevent high voltage rapidly changing voltages
on one side of the circuit from damaging components or distorting transmissions on the
other side.
