Ok, theres 4 wires, theres a red white black and blue, i know where to hook the red and black obviously, but the white says to connect to any auxiliary unit that accepts a 0-5 volt input, where would i connect that and also the blue says to connect to a RS-232 com port for hyper-terminal data logging, now where would i connect those 2 wires to??

i believe the white one is only used if you are hooking it up to a datalog or sometime so you can see you logs on your laptop
