My understanding is that the Topcon X30 requires .XML files. When going to Write job data - if you do not see Topcon as a option, close WJ Data and go to Help - check for updates. You may need to check the box to Show all available components. Check the box for the ISO Task data driver and click OK. The FODD will download and explain you need to close Farm Works. Click OK and manually Close Farm Works. An install box will then display to run this FODD installation for the ISO Task data driver. When complete, answer Yes to restart Farm Works. Now when you go back to File - Write Job Data Topcon should display and when you open should see the option for the Topcon X30 -ISOXML (*.XML). Reminder to make sure the correct Client/Farms/Fields are selected from the Resource List button and also from the Advance Setup button you are selecting the correct Task Controller Version option matching your device firmware version.
