    Hi

    I have circuit board that requires a jumper be moved from posts 1&2, to 2&3 in order to program it. I want the ability to remotely over net, "switch" the posts back and forth. So I can put in program mode, program it(2&3h, then put it back in "run" mode(1&2),

    I have the board connected via USB to a pc that can rdp into, but have to go to site every time to move the jumper.

    Any ideas?

    Thanks

    An SPDT relay would do the job, but the relay will need some power - what's available? - and it will need a control signal - have you got one of those handy? If you are programming this 'thing' does it have a spare output you hijack?

    Get an Arduino ethernet shield.

    So many different ways. We need more info about the circuit.
