Setup<\/h2>\n
    \n\t
  1. Alicat Python and Python-driven command prompt (Windows Powershell) drivers have been developed principally by Pat Fuller at NuMat Technologies. Download the drivers from github.com: https:\/\/github.com\/alexrudd2\/alicat<\/a><\/li>\n\t
  2. In order to run the command prompt\/Powershell driver, Python will first have to be installed on the computer. Install the latest stable Python 3 release: https:\/\/www.python.org\/downloads\/<\/a><\/li>\n\t
  3. Once Python has been installed, command the following in the command prompt:<\/li>\n<\/ol>[\/et_pb_text][et_pb_image src=”https:\/\/www.alicat.com\/wp-content\/uploads\/2024\/05\/1-1024×67-1.webp” title_text=”1-1024×67″ _builder_version=”4.25.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][et_pb_text _builder_version=”4.25.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

     <\/p>\n

    4. If the Python PIP package manager is installed and enabled, command the following instead<\/p>[\/et_pb_text][et_pb_image src=”https:\/\/www.alicat.com\/wp-content\/uploads\/2024\/05\/2-1024×34-1.webp” title_text=”2-1024×34″ _builder_version=”4.25.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][et_pb_text _builder_version=”4.25.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

     <\/p>\n

    Command Prompt (Powershell) usage<\/h2>\n
      \n
    1. Enter \u201calicat \u2013help\u201d or \u201calicat -h\u201d to access a menu of possible arguments and usage information<\/li>\n<\/ol>[\/et_pb_text][et_pb_image src=”https:\/\/www.alicat.com\/wp-content\/uploads\/2024\/05\/3-1024×530-1.webp” title_text=”3-1024×530″ _builder_version=”4.25.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][et_pb_text _builder_version=”4.25.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

       <\/p>\n

        \n
      1. \n
          \n
        1. If you only have one Alicat connected to your target COM port, command the port name to return data from the Alicat:<\/li>\n<\/ol>\n<\/li>\n<\/ol>[\/et_pb_text][et_pb_image src=”https:\/\/www.alicat.com\/wp-content\/uploads\/2024\/05\/4-1024×34-1.webp” title_text=”4-1024×34″ _builder_version=”4.25.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][et_pb_text _builder_version=”4.25.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

           <\/p>\n

            \n
          1. To poll a device with unit ID A, enter the following command<\/li>\n<\/ol>[\/et_pb_text][et_pb_image src=”https:\/\/www.alicat.com\/wp-content\/uploads\/2024\/05\/5-1024×34-1.webp” title_text=”5-1024×34″ _builder_version=”4.25.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][et_pb_text _builder_version=”4.25.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

             <\/p>\n

              \n
            1. The response from either of these commands (step 2 or 3) should look like this:<\/li>\n<\/ol>[\/et_pb_text][et_pb_image src=”https:\/\/www.alicat.com\/wp-content\/uploads\/2024\/05\/6-1024×165-1.webp” title_text=”6-1024×165″ _builder_version=”4.25.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][et_pb_text _builder_version=”4.25.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]
              \n
              \n
              \n
              \n
              \n
              \n
              \n
              \n
              \n

              Python usage<\/h2>\n

              Use this command to open a serial connection to an Alicat device on the specified port:<\/p>\n<\/div>\n<\/article>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n<\/div>[\/et_pb_text][et_pb_image src=”https:\/\/www.alicat.com\/wp-content\/uploads\/2024\/05\/image-6.png” title_text=”image (6)” _builder_version=”4.25.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][et_pb_text _builder_version=”4.25.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

              If the Alicat is communicating on the specified port, it will return the same dictionary as when polled via Powershell.<\/p>\n

              Using this with Windows COM port COM1, for example, would look like this:<\/p>[\/et_pb_text][et_pb_image src=”https:\/\/www.alicat.com\/wp-content\/uploads\/2024\/05\/8-1024×67-1.webp” title_text=”8-1024×67″ _builder_version=”4.25.1″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][\/et_pb_column][\/et_pb_row][\/et_pb_section]\n","protected":false},"featured_media":46458,"parent":0,"template":"","meta":{"_acf_changed":false,"_et_pb_use_builder":"on","_et_pb_old_content":"","_et_gb_content_width":"1920","content-type":"","_searchwp_excluded":""},"categories":[],"class_list":["post-38144","support","type-support","status-publish","has-post-thumbnail","hentry"],"acf":[],"yoast_head":"\nPython and Command Prompt Communication Instructions -
