my board is made by Epox, model - 4b2m. The jumper is set out like this. 1 2 3 . . . the shunt is currently over 1 and 2 and is the default setting placing the shunt over 2 - 3 is the reset setting. I have not been able to find a specifice mehtod in the manual for doing this. Do i want the power on when i short the pins? Do i want the shunt on?
