This is why you should follow a few basic rules • Work carefully. • Check the movement of all parts. • Use the interface test. – Before you start to write a program for a model, you should test all parts that are connected to the Interface, using the interface test from the ROBO Pro software. Interface Test Prog Button • Programs can be downloaded to the interface. • Two programs can be stored in the Flash memory. • Toggle between the two programs using the Prog Button. Port Button • This button can be used to toggle between the COM/USB or IR Ports. • The light remains solid once you’ve selected the port. Troubleshooting • Interface Test • Cables and Wiring • Loose Connection – Loose plugs – Poor contact between wire and plug • Short Circuits • Programming Errors
