Simplex can be viewed as a communications "one-way street". Data only flows in one direction. That is to say, a device can be a receiver or a transmitter exclusively. A simplex device is not a transceiver. A good example of simplex communications is an FM radio station and your car radio. Information flows only in one direction where the radio station is the transmitter and the receiver is your car radio.
Simplex is not often used in computer communications because there is no way to verify when or if data is received. However, simplex communications is a very efficient way to distributed vast amounts of information to a large number of receivers. Duplex communications overcome the limits of Simplex communications by allowing the devices to act as transceivers. Exactly when data flows bi-directionally further defines Duplex communications.
Full Duplex devices can transmit and receive data at the same time. RS is a fine example of Full Duplex communications. There are separate transmit and receive signal lines that allow data to flow in both directions simultaneously.
RS devices also operate Full Duplex. Half Duplex devices have the dubious honor of allowing both transmission and receiving, but not at the same time. Essentially only one device can transmit at a time while all other half duplex devices receive. Devices operate as transceivers, but not simultaneous transmit and receive. RS operates in a half duplex manner. Here is the short version of the critical specifications. Unfortunately, these are subject to interpretation by individual manufacturers.
That is why RS is often regarded as an incredibly un-standard communications protocol. If you're purchasing an adapter, I will not be able to provide recommendations. There are multiple ways to approach this problem, this is just one example. Sign up to join this community. The best answers are voted up and rise to the top.
