    Initial Operation page 17 Digital I/O Module Description The Keysight E1458A 96-Channel Digital I/O Module (referred to as the "digital I/O module") is a 12-port digital input/output module intended for data communication and digital control in electronic environments. The digital I/O module is compatible with TTL levels (0-5V) and CMOS levels (using an external pull-up).

    The most common line to be used is line one, as this is the usual default interrupt line. Many VXIbus commanders have a way to change the interrupt line they manage (for example, the Keysight E1405/E1406 has an interrupt line allocation table). When doing direct register-based programming (instead of using the register-based SCPI driver), set the interrupt line to a line that is not used by the register-based SCPI driver.

    The SCPI command for inputting the state of a single bit on a data port is: MEASure:DIGital:DATAn[:type]:BITm? This command instructs the Keysight E1458A Digital I/O Module to return a value of either 0 or 1, indicating the condition of bit m on port n, following completion of the input handshake.

  • Page 53: Output

    The SCPI command requesting an 8-bit byte from a data port is: MEASure:DIGital:DATAn[:BYTE][:VALue]? This command instructs the Keysight E1458A Digital I/O Module to return a decimal value between 0 and 255, indicating the condition of the data lines on port n, following completion of the input handshake. The value returned depends upon the programmed state of the port POLarity.
