Hi @deltahotel, thanks for your query. I am afraid that we have not done any official testing with the ET5 and Tablets so we cannot offer official guidelines as to proper operation, however so long as the machine meets the minimum ET5 hardware specifications and there is the means to properly mount the tracker, it should be ok. With regard to a USB converter, again this is an untested setup should still work. Sorry we cannot provide further details, but please let us know how you get on. Best Wishes.
