If you are using Ubuntu, CuteCom is available in the Ubuntu Software Center.<\/p>\n<p>Next, install the drivers for your USB-serial cable.

The connector should be oriented such that the black wire is closest to the &#8220;blk&#8221; silkscreen label on the PCB, and the green wire closest to the &#8220;grn&#8221; label.<\/p>\n<p>If you are using the FTDI Friend, match the writing on the silkscreen of the FTDI Friend to the labels on the Geiger Counter &#8211; BLACK goes towards blk, GREEN towards grn.<\/p>\n<p><a href=\"http:\/\/www.flickr.com\/photos\/mightyohm\/6848906911\/in\/photostream\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/live.staticflickr.com\/7019\/6848906911_c30d6a0f8d_n.jpg\" alt=\"FTDI cable connected\" width=\"320\" height=\"240\" \/><\/a><\/p>\n<h4>Step 3: Configure your serial terminal<\/h4>\n<p>Launch the serial terminal program you installed in step 1. \u00a0If you are using RealTerm on Windows, you&#8217;ll see a window like this pop up:<\/p>\n<p><a href=\"http:\/\/mightyohm.com\/blog\/wp-content\/uploads\/2012\/02\/realterm.png\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"4715\" data-permalink=\"https:\/\/mightyohm.com\/blog\/2012\/02\/tutorial-geiger-counter-data-logging\/realterm\/\" data-orig-file=\"https:\/\/mightyohm.com\/blog\/wp-content\/uploads\/2012\/02\/realterm.png\" data-orig-size=\"702,448\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;}\" data-image-title=\"RealTerm\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/mightyohm.com\/blog\/wp-content\/uploads\/2012\/02\/realterm.png\" class=\"alignnone size-medium wp-image-4715\" title=\"RealTerm\" src=\"http:\/\/mightyohm.com\/blog\/wp-content\/uploads\/2012\/02\/realterm-500x319.png\" alt=\"\" width=\"500\" height=\"319\" srcset=\"https:\/\/mightyohm.com\/blog\/wp-content\/uploads\/2012\/02\/realterm-500x319.png 500w, https:\/\/mightyohm.com\/blog\/wp-content\/uploads\/2012\/02\/realterm.png 702w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><\/p>\n<p>Now it&#8217;s time to configure your serial program. \u00a0I&#8217;m going to show how to do this in RealTerm. \u00a0If you&#8217;re using another serial program (or another operating system), the procedure will be slightly different, but the settings are the same.<\/p>\n<p>In the RealTerm window, click on the &#8220;Port&#8221; tab and you&#8217;ll be confronted with a number of options. \u00a0Don&#8217;t worry, this is actually pretty simple: You want to select the serial port number or name corresponding to the FTDI cable (port number 22, in my case), and configure the port as follows:<\/p>\n<ul>\n<li>Baud: 9600<\/li>\n<li>Data Bits: 8<\/li>\n<li>Stop Bits: 1<\/li>\n<li>Parity: None<\/li>\n<li>Hardware Flow Control: None<\/li>\n<li>Software Flow Control: Off (nothing selected)<\/li>\n<\/ul>\n<p>Aside from the baud rate, the rest of the options should correspond to the defaults.
