Introduction
Software Utility
Responding to the industrs need for high-density digital input/
output modules, the ADLINK PCI-7442/7443/7444 DIO card series
AD-Logger
delivers up to 128 opto-isolated channels for a wide range of
demanding PCI-based applications. The PCI-7442/7443/7444 series
comes with 64 (PCI-7442) or 128 (PCI-7443) opto-isolated digital

inputs and 64 (PCI-7442) or 128 (PCI-7444) opto-isolated digital

by accidental contact with external voltage while promoting simple
ground connections. All input channels are identical non-polarity ACL-10568NF-1
with each line isolated and suited to collect digital inputs even
68-pin SCSI-VHDCI flat cable
at high-noise environments. Featuring a Change-of-State (COS)
interrupt function, the PCI-7442/PCI-7443 instantly generates an

interrupt request to the PCI controller when it detects a sharp
change in the logical state of any of its digital inputs.
