Appendix B: RS-232 Electrical

Interface

The most widely used communication standard is RS-232. It’s been defined and revised several times and is sometimes also called EIA/TIA-232. The IBM AT computer defined the RS-232 port on a DB9 connector, and subsequently the EIA/TIA approved this implementation as the EIA/TIA-574 standard, which is defined as the “9-Position Non-Synchronous Interface between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange.”

RS-232 can operate at data rates of up to 20 kbps at distances less than 50 ft. (15.2 m). The absolute maximum data rate may vary depending on line conditions and cable lengths. RS-232 is a single-ended or unbalanced interface, meaning that a single electrical signal is compared to a common signal (ground) to determine binary logical states. The RS-232 and the EIA/TIA-574 specification define two types of interface circuits, Data Terminal Equipment (DTE) and Data Circuit- Terminating Equipment (DCE). The Serial Host Adapter is a DTE device.
