Rx: A medical prescription. The symbol Rx is usually said to stand for the Latin word recipe meaning to take.. It is customarily part of the superscription (heading) of a prescription.
We talk about 0 and 1 but often they are voltages. So what is zero and one. RX- is the base voltage. So by examine RX+ you can say does RX+ = RX- then zero otherwise if RX+ is significantly greater than RX- then one. So the word significant means that RX- and RX+ are different enought not to be caused by natural electrical properities of the cables and connectors. Obviously it is a bit more complex than this.
