Communication with External Instruments Using 24-bit I/O Port
Reading data input to port
When port C, D, or E is configured to input port, the binary data represented with
High(0)/Low(1) of each bit of the port is read as decimal data.
To retrieve the data, use the following commands as query:
Port Name Command
Port C :CONTrol:HANDler:C[:DATA] on page 222
:CONTrol:HANDler:D[:DATA] on page 223
Port D
Port E :CONTrol:HANDler:E[:DATA] on page 224
Data output to port
Binary data (decimal data when output data is specified with a command) represented with
High(0)/Low(1) of each bit of the port can be output to ports A through F (ports C, D, and
E should be configured to output ports).
To output data, use the following commands.
Port Name Command
Port A :CONTrol:HANDler:A[:DATA] on page 221
Port B :CONTrol:HANDler:B[:DATA] on page 222
:CONTrol:HANDler:C[:DATA] on page 222
Port C
Port D :CONTrol:HANDler:D[:DATA] on page 223
Port E :CONTrol:HANDler:E[:DATA] on page 224
:CONTrol:HANDler:F[:DATA] on page 224
Port F
