설명The OMG-USB-DIO Series contains 48 or 96 channels of buffered digital I/O emulating 8255s for industrial control applications. 10K pull up resistors are included on each port bit. The OMG-USB-DIO series contains 8 bit I/O ports configurable as inputs or outputs. This gives the user the ability to customize the combination of inputs or outputs as needed. In addition, the low order bit of the first port can be set to generate an interrupt for status monitoring applications. A special factory configurable interrupt feature allows the user to request conditional I/O combinations for interrupt generation. When the I/O combinations occurs, a hardware interrupt is triggered.
