    1. Question can four of these units be ganged together to be operated by a single switch to control on off operation?
    2.In the specification window of control function test i.e.POWER ON it states
    rc-Vin <1 vdc or open AND POWER OFF R.C.-Vin>4 VDC or short.. Is Vin positive or neg?( I would like to go the open or short route) I am not clear how to wire this ..any help to clear this up would be much appreciated.....

    I see no reason that you couldn't gang them. Does it really matter what it takes to turn on/off. You would just flip your logic as required.
