Adding switch to device

  1. I added a switch to a velleman pcs500(amazing that they didn't add one but I
    should have known better) because for some reason it does not automatically
    turn off when not in use. In any case I'm wondering if there can be any
    detrimental effect by doing this? There are no inductors on the circuit
    board so I don't see any issue with kickback. It uses 9VDC and I added the
    switch between the power jack and the circuit board.


    Thanks,
    Jon

    Hi, Jon. I'd just put the adapter plug for the PCS on the PC power
    strip, and have the PCS500 on whenever the PC is on.

    But since the connection between the PCS500 and the PC is through the
    printer port, it shouldn't hurt either the PCS or the PC to have one
    off and the other on.

    However, you may have some difficulty with your PCS software
    initializing the printer port if you turn on the PCS after the PC has
    started. Try it and see. Hey, if it works, it works.

    Cheers
    Chris
