Remote Access Connection Instructions What makes these lectures different and unique from other classroom lectures is that we have incorporated a section in each activity to remotely acess laboratories, lecturers from your classroom. Request a remote lecture/lab session specifying information such as: the day, the time, and the instrument you are interested in using by visiting our web site: http: //netchem. ac. rs/remote-access You will see the list of partners with the instruments provided to chose from. You will be contacted by a Remote Access staff member to set up a test run to ensure you are set up properly and have the required infrastructure. In some cases it will be possible to send samples or verify the in-house sample you would like us to prepare and load for characterization. There are two communications software packages, that will allow us to communicate instructions and answer questions during the session. - Team. Viewer: You can obtain a free download at: https: //www. teamviewer. com/en/index. aspx - Skype ___________________________________________________ This project has been funded with support from the European Commission.

Remote Access Connection Instructions • Instructions for using Team. Viewer are in detail explained in Deliverable 2. 2 named Guidelines for courses publishing by WARIAL networking (http: //www. netchem. ac. rs/documents/category/52 -deliverables) • In brief, • The meeting function allows a host to present video call (Video Conference) from a laboratory or the content of his screen (Remote Desktop Share) to other participants (guest). Up to 25 users can join a meeting. • For both Educational (one side is dominantly receptive) and Consultative (two sides are equal in giving-receiving information) information exchange types Video Conference and Remote Desktop Share can be arranged. ___________________________________________________ This project has been funded with support from the European Commission.
