Does anyone know the the power supply pinouts for a BEFSR81 router? I think it is 5 V. The pins are arrainged in a triangle. I think the top pin is ground. Which of the other ones is return and which is +5V.? Please tell me how you measured it so I do not make the classic mirror image mistake. i.e. looking at the cable or looking at the back of the router. I have to McGyver a power supply. j.c.
