    This product converts digital data to analog signals according to the resolution. You can set a variety of conditions for analog output, including the output channel, sampling period, and sampling start/stop conditions. Analog output processes are classified as follows: AO-1604LX-USB...

  • Page 43: Setting The Conversion Conditions

    When the device covers the range of 0 - 10V, the minimum unit of converted voltages is 10÷4096 ≈ 2.44mV. If the device has a resolution of 16bit, it is 10 ÷ 65536 ≈ 0.153mV instead. AO-1604LX-USB : The resolution is 16bit. Channel "Channel"...
  • Page 44 The analog signal corresponding to the output data contains an error as follows: - Output data "42598" converted to: 2.9998 V - Output data "42599" converted to: 3.0001 V This error is a consequential error occurring when output data is obtained from an expected analog value. AO-1604LX-USB...
  • Page 45 When conversion starts, the device starts outputting the output data. The device buffer can operate as FIFO or RING memory. Device buffer mode handles conversion data by sampling count and API functions are provided to retrieve conversion data directly as voltage values. Device buffer mode AO-1604LX-USB...

  • Page 47 The number of repetitions is set by software and sampling is repeated for the specified number of times. You can also specify that operation continue indefinitely. If set to repeat indefinitely, analog output operation is stopped by outputting a analog output stop command by software. AO-1604LX-USB...
  • Page 48 When using FIFO format, setting data to memory is always performed from the most recent data. New data can be added during conversion. Procedure for RING format When using ring format, a ring memory area large enough for the data to be set is reserved. Data cannot be modified during DA conversion. AO-1604LX-USB...
  • Page 49 The following events can be used in combination depending on the specifications and purpose of the application. ”DA conversion start condition satisfied” event This event occurs when the DA conversion start condition is satisfied.
