34952A Multifunction Module 34952A Multifunction Module The 34952A Multifunction Module with DIO, D/A, and Totalizer combines four 8- bit ports of digital input/output, a 100 kHz totalizer, and two ±12 volt earth- referenced analog outputs. You can include digital inputs and totalizer input in a scan list. You can make connections via standard 50- pin D- sub cables or the optional 34952T terminal block.
34952A SCPI Programming Examples 34952A SCPI Programming Examples The programming examples below provide you with SCPI command examples to use for actions specific to the general purpose switch modules. The slot and channel addressing scheme used in these examples follow the form sccc where s is the mainframe slot number (1 through 8) and ccc is the channel number. For information on specific configurations, refer to the simplified schematic on page 4.
34952A SCPI Programming Examples Example: Configuring the totalizer for count This command configures the totalizer to count on the rising edge (positive) or falling edge (negative) of the input signal. The following command configures the totalizer (channel 5) on a Multifunction module in slot 3 to count on the negative edge (falling) of the input signal.
