#146732 - A == + or A == -? Responding to: ???'s previous message |
Erik said:
I read and read and finally found out that LT and B & B electronics do not agree whether A or B is the positive node, reversed the wires and it works now. You and LT and B & B are not alone. The last project I worked on had an RS485 port. When the board was being designed, the hardware guy got so confused over this very thing that he finally just gave up and put a couple of jumpers on the board so A and B could be easily swapped. -- Russ |
