PCIe-Mini-DIO16/32 16 channels RS-422/485 or 32 channels LVTTL

Compatible Operating Systems: Windows, Linux, VxWorks, C library dll’s

Supported Architectures: PCI Express Mini

The PCIe-Mini-DIO16/32 is a PCI Express Mini board. It has 32 I/O channels that can monitor or control the on/off (high/low) status of up to 16 differential devices or up to 32 channels LVTTL, software selectable in groups of 2. Each channel can be used as an input or output. Input channels can be configured with interrupts to detect a change of state, or level detection of any bit. The RS-422/485 input threshold includes hysteresis for increased noise immunity.
