For example, a terminal that has onboard female connectors to come with a cable that has a male connector at each end fully meets the RS-232 standard. However, there are devices with all sorts of connector gender/pin definitions combinations. In accordance with RS-232 standard, DCE is meant for female connectors, and DTE is for male connectors.

driver current in High Z state: +/-6mA +/-2v (power off) Driver load impedance: 3000-7000 Ohms Driver output signal level: +/-5V to +/-15V (loaded) or +/-25V (unloaded) Receiver input resistance: 3000-7000 Ohms Receiver input voltage range: +/-15V Receiver input sensitivity: +/-3V Total Number of Drivers and Receivers on One Line: 1 driver and 1 receiver RS232 Standart Limitations With all its merits, RS-232 has some serious limitations in range and data throughput performance, so its main scope of application is industrial gear, networking, and lab equipment. However, this standard supports synchronous transmission too. For PC, the most common configuration is asynchronous link sending 7-bit or 8-bit packets. It defines not only electrical signal characteristics, such as signal transmission rate, voltage levels, cable length, timing and short-circuit behavior, but many other things as well, including interface’s mechanical characteristics, connectors, and pinouts.Īccording to RS-232 standard, all the data is transmitted in a time-series of bits. RS-232 is a standard that was introduced in the early 60s for serial data transmission and still widely in use mainly because it’s multipurpose, easy to operate and maintain, accessible, and widely supported. What is RS232 Serial Communication Protocol?
