4102 SeaLINK+485: Ethernet to 1-Port RS-422/485

The PIO-48.PCI provides 48 channels of buffered drive digital I/O emulating 8255 mode zero, which can be utilized for PC based control and automation of equipment including sensors, switches, security control systems, and other industrial automation systems. Optional pull up resistors are available providing a known state power up condition. The PIO-48.PCI board contain 6 groups of eight-bit I/O ports, configurable as inputs or outputs to suit the automation task. The mode of each of the ports is user selectable as inputs or outputs by simply writing a control word to the port register. This gives the user the ability to customize the combination of inputs and outputs as needed. The low order port of the first bit can be set to generate an interrupt for status monitoring applications. A special factory configured interrupt feature allows the user to request conditional I/O combinations for interrupt generation. When the I/O combination occurs, a hardware interrupt is triggered.
