Single-E nded Data T ransmission
Single-ended interfaces are used for low speed, short distance
communications such as from a computer terminal to a printer.
A single line is used to carry the signal. Various standards have
been developed to standardize the communication link, the most
popular of these being the RS-232. T he RS-232 standard was
introduced in 1962 by the EIA and has been widely used
throughout the industry. T he standard has been revised several
times, and the current revision is known as EIA-232E. T he
RS-232 standard is suitable for single-ended data transmission
at relatively slow data rates over short distances. A typical
RS-232 interface is shown in Figure 14.

Differential Data T ransmission
When transmitting at high data rates, over long distances and
through noisy environments, single-ended data transmission is
often inadequate. In this type of application, differential data
transmission offers superior performance. Differential transmis-
sion uses two signal lines to transmit data. It rejects ground
shifts and is insensitive to noise signals which appear as com-
mon mode voltages on the transmission lines. T o accommodate
faster data communication, the differential RS-422 standard was
developed. T herefore, it can be used to reliably transmit data at
higher speeds and over longer distances than single-ended trans-
mission. A typical RS-422 interface is shown in Figure 15.
