  • Page 61 Appendix C: Industrial Devices The advantages of single-ended transmission are simplicity and low cost of implementation. A single-ended system requires only one line per signal. It is therefore ideal for cabling, and connector costs are more important than the data transfer rate, e.g. PC, parallel printer port or serial communication with many handshaking lines, e.g. EIA-232. Cabling costs can be kept to a minimum with short distance communication, depending on data throughput, requiring no more than a low cost ribbon cable.

On one line, a true signal is transmitted, while on the second one, the inverted signal is transmitted. The receiver detects voltage difference between the inputs and switches the output depending on which input line is more positive.
