What software/ hardware do i need to read OBD2 Codes

Thank you theoneandonly for making this guide. When I was hankering to purchase the MultiECUscan software, reading through their site and getting confused with the many possible cables one can use, I just wanted to know what will work with my Ducato. Your guide here gave me the confidence and I purchased the Vgate and the OBDLink SX, just as you've shown here. Easy to install and works a treat. Thanks again for your efforts.
