PCL-800 series communication card provides reliable, high-speed serial communication. The unique shared interrupt can be set to most common (extended) AT interrupts. This
simplifies programming, speeds up interrupt processing and frees up interrupts for other devices. PCL-800 series cards also provide EFT surge or isolation protection to prevent
your PC and equipment against damage from ground loops, increasing system reliability in harsh environments or abrupt high voltage surges such as those caused by lightning
during thunderstorms.
