# Tips
- Check first if you can interface with the Graphtec by accessing the IP address in a browser. Graphtec IP can be found and changed on the device at "Menu > I/F > IP ADDRESS".
- See the manuals [APS GL-Connection](http://www.graphtec.co.jp/site_download/manual/APS(GL-Connection)-UM-159-05.pdf) and [Graphtec GL840](http://www.graphtec.co.jp/site_download/02_manual/data/GL840-UM-852.pdf)
- The type of connection might be different, for me it was a Socket connection (line 13). See types of connections at [PyVisa documentation](https://pyvisa.readthedocs.io/en/1.8/names.html#visa-resource-syntax-and-examples)
- At start, sometimes the Graphtec does not seem to connect. Try accessing the Graphtec directly from browser (simply plug the ip address into the address bar). You should see an interface. Only one connection with the Graphtec may be open, so close the browser when you run the code. Code should work when this works, otherwise the problem lies somewhere else.
