How do I connect an Alicat device to FlowVision?<\/h2>[\/et_pb_text][et_pb_video src=”https:\/\/youtu.be\/1cFxkOSNwCA” _builder_version=”4.27.4″ _module_preset=”default” max_width=”80%” max_width_tablet=”90%” max_width_phone=”100%” max_width_last_edited=”on|phone” module_alignment=”center” custom_margin=”1rem||1rem||true|false” global_colors_info=”{}”][\/et_pb_video][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” text_font_size=”16px” custom_css_free_form=”selector h2 {|| margin-top: 2rem;|| padding-bottom: 0;||}||||selector p,||selector ul {|| padding-bottom: 0 !important;||}” global_colors_info=”{}”]

What do the \u201cFailed to Establish Serial Port Connection\u201d and \u201cAccess is Denied\u201d errors mean?<\/h2>\n

This message occurs when multiple programs in Windows try to access the same serial port. For example, this error will show when FlowVision 2.0 is open and connected to serial port COM4, and you then try to connect to COM4 via another serial terminal application like Alicat Serial Terminal or PuTTY.<\/p>\n

What do I do if my device cannot be found?<\/h2>\n
    \n
  • Check that all Alicat devices have a unique unit ID, so the computer can distinguish them.<\/li>\n
  • Check that all devices are powered. A USB or serial port on a computer does not have enough power to power an Alicat device.<\/li>\n
  • Check that the baud rate on the device and on FlowVision are the same.<\/li>\n
  • Check that the COM port is correct in \u201cDevice Manager.\u201d<\/li>\n<\/ul>\n

    How do I create a chart in FlowVision?<\/h2>[\/et_pb_text][et_pb_video src=”https:\/\/youtu.be\/vzsuyr7L7zM” _builder_version=”4.27.4″ _module_preset=”default” max_width=”80%” max_width_tablet=”90%” max_width_phone=”100%” max_width_last_edited=”on|phone” module_alignment=”center” custom_margin=”1rem||1rem||true|false” global_colors_info=”{}”][\/et_pb_video][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” text_font_size=”16px” custom_css_free_form=”selector h2 {|| margin-top: 2rem;|| padding-bottom: 0;||}||||selector p,||selector ul {|| padding-bottom: 0 !important;||}” global_colors_info=”{}”]

    Is it possible to Start\/Stop the measurement when you are in the Charts page?<\/h2>\n
      \n
    • To start\/stop the chart polling<\/em> without affecting the device measurement:<\/strong> Set the chart rate to 0 and press enter on your keyboard.<\/li>\n
    • To start\/stop the device polling<\/em> without affecting charting:<\/strong> Enable Polling Control in the FlowVision settings, then (optionally) drag the device view below the chart and click the Pause\/Resume Polling button.<\/li>\n<\/ul>\n

      When using \u201cSave Image,\u201d is it possible to set the green time marker and make the chart freeze so you can take the screenshot?<\/h2>\n

      The chart can be effectively \u201cfrozen\u201d by disabling the \u201cAuto Track X\u201d button which will continue to measure and chart new data but will not keep the X-axis synchronized with it.<\/p>\n

      The \u201cSave Image\u201d function always has a black background. Can I change this to white?<\/h2>\n

      You can change from dark to light mode with the \u201cdisable dark mode\u201d setting.<\/p>\n

      How do I set two time markers (one at the start and one at the end) and take a picture?<\/h2>\n
        \n
      • Toggle on the time range selectors on the chart.<\/li>\n
      • The range selectors will be displayed and Auto Track X will be temporarily disabled.<\/li>\n
      • Drag the range selectors to the start and end of the time span you want to zoom to, then click \u201cZoom to Selection.\u201d<\/li>\n
      • The chart will be zoomed to the selection. From here you can use the \u201cSave Image\u201d button as normal.<\/li>\n<\/ul>\n

        What is the purpose of \u201cLog serial Data\u201d?<\/h2>\n

        When enabled, this feature will log the data received from a connected device into a .CSV file on your desktop. This data is generally used for debugging purposes. If you\u2019d like a .CSV file of your device\u2019s data output, the Logs function is the best option as it will allow you to control the structure and timespan of the output.<\/p>[\/et_pb_text][et_pb_code _builder_version=”4.27.4″ _module_preset=”default” locked=”off” global_colors_info=”{}”]
