PCL-858 User's Manual
Description
The PCL-858 series are eight ports serial communication interface
card. The PCL-858A/858B serial ports are implemented using
16C554 UARTs which makes serial I/O more reliable.
The PCL-858 series support all eight ports can be set the address
automatically. All channels share the same interrupt (IRQ), and
interrupt status register is available for determining the interrupt
source. When an on-board interrupt occurs the interrupt status register
(vector address) indicates which port has generated it. The 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.
The PCL-858 series developed by Advantech Co., Ltd has passed the
CE test for environmental specifications.
