4. Functions
This section describes the functions of the board.
Each function described here can be easily set and executed by using the bundled API function library.
For details, refer to HELP after installing API-PAC(W32).
Data I/O Function
Data Input
When input data is “ON”, “1” is input to the relevant bit.
When the input data is “OFF”, in contrast, “0” is input to the relevant bit
Data Output
When “1” is output to the relevant bit, the corresponding transistor is set to “ON”.
When “0” is output to the relevant bit, in contrast, the corresponding transistor is set to “OFF”.
When the PC is turned on, all output are reset to 0 (OFF).
Monitoring Output Data
The < PIO-64/64L(PCI)H > and < PO-128L(PCI)H > can read the state of the data currently being
output without affecting the output data.
