fDesc[0] = "The SXAO Utility isn&#039;t provided on CD as part of the SX AO-LF package. Instead, you need to download it. This is understandable because it&#039;s mostly intended as a firmware update utility (the latest firmware comes packaged with the utility in the form of a .hex file). <br /> <br /> It&#039;s definitely worth downloading the SX AO utility as it provides some really nice, simple and reassuring test features. The advantage of using the SXAO utility is that it&#039;s very straightforward and requires no setup whatever - all you need to do is select the correct COM port the AO is connected to. Essentially, if the tests detailed below work then you&#039;re ready to move on and tackle the more complex setup required in MaxIm.<br /> <br /> If the Calibrate, Version or Handshake buttons do not produce a positive result (look in the status bar for short messages) then at a basic level the connection between your computer and the AO unit is not functioning correctly. <br /> <br /> In the case of bad serial-to-USB cable, clicking the version button would produce &#039;Unknown Version&#039;. You should expect to see &#039;Version 20&#039; or higher. If you run into problems at this stage then ensure that the AO really is connected to the COM port you select (look in Windows device manager to verify).";
