The following material is copied from: RS is a standard for the transmission of serial data long a hard wired cable. Although not widely used in domestic environments, it is widely used for data acquisition applications. Often RS links are used for simple networks, and they may be connected in a 2 or 4 wire mode. In a typical applications several address able devices may be linked to a single controlled PC , and in this way a single line may be used for communication. Using RS, it is possible to construct a multi-point data communications network. The standard specifies that up to 32 drivers or transmitters along with 32 receivers can be used on a system. This means that there can be 32 nodes capable to both transmit and receive. In this way it is possible to have hundreds of nodes on a network. As RS networks become larger, the problem of data collisions becomes greater. This can be solved, at least in part by ensuring the hardware units converters, repeaters, micro-processor controls are designed to remain in a receive mode until they are ready to transmit data. The hardware detects the start-bit of the transmission and thereby enables the transmitter. Once a requested data is sent the hardware reverts back into a receive mode.
