Description
1 Design Requirements
I wanted a simple way to troubleshoot 9 pin serial connections, by determining which pin had activity and allowing for swapping of pins without having to resolder/recrimp connections.
2 Usage
The 9 dip switches allow for mixing of any combination of the inputs to the output switches. The Red LED indicates positive voltage while the Green LED indicates negative voltage. Along with the resistor, they are all 0805 which makes it easy to hand solder.
