In accordance with RS-232 standard, DCE is meant for female connectors, and DTE is for male connectors.

RS-232 doesn’t solve the problem presented by single-ended signaling.Īn RS-232 device is either as a Circuit-terminating Equipment (DCE) or as a Data Terminal Equipment (DTE) depending on which wires are used to send and receive each signal.

The need for a null modem or crossover cable whenever connecting a peripheral to a computer.

Although the multi-drop connection issue has been addressed with more reliable alternatives, it still doesn’t compensate for the compatibility and speed limitations of RS232 port.

A lot of devices don’t use the handshake lines for flow control thereby making RS-232 unreliable.

Increased consumption of power due to large voltage swing is a huge complication for the power supply design.

Here are the obvious limitations of the standard:

What are the known issues with the RS-232 serial port? Using the standard COM port comes with a bunch of limitations that you have to deal with.

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.
