I have 6 inputs on a robot controller. The inputs are weighted 1-2-4-8-16-32. The robot controller looks at these inputs to see what program is selected. If input 2 is low then program 2 is ran. If inputs 1& 2 is low then program 3 is ran. If inputs 2 & 6 is low then program 34 is ran. As you can tell the robot controller decodes the binary inputs into decimal. I hooked up two BCD thumb wheel switches to the inputs and it works ok from 0-9, but when I dial in 10 the controller sees the number 16. What type of two digit thumb wheel switch do I need so the controller will see all of the possible 64 combinations?
