                Frequently Asked Questions (FAQ)

                • Q: Where can I find a MAX232 circuit diagram?

                  A: The Max-232 IC is started by the maxim integrated products in 1987. It is an integrated circuit which converts the signals from the RS232 serial port to the proper signal which are used in the TTL compatible digital logic circuits. The MAX232 can convert the signals like RX, TX, CTS, and RTS and it is a dual driver/receiver. The driver increases the output voltage levels of TIA232 from a 5 volt supply to 7.5 volts by using the external capacitor and on chip charge pumps. more

                • Q: How do I connect a MAX232 to an Arduino?

                  A: In this tutorial you will learn how to communicate with a computer using a MAX3323 single channel RS-232 driver/receiver and a software serial connection on the Arduino. more

                • Q: How do I convert RS232 port data to Universal Serial Bus (USB) port?

                  A: The chipsets for USB slave converters, manufactured by Future Technology Devices International, are able to convert any RS232 port data to Universal Serial Bus (USB) port. more

                • Q: Where can I find a MAX232 schematic diagram?

                  A: The first thing we do is make a block diagram. This is a diagram of our gadget, split into blocks. This is a good aid to keep us on track and it gives us an overlook of what we want our circuit to do. more

                • Q: Where can I see a MAX232 features list?

                  A: TTL/CMOS to RS232 Converter IC; Can support two conversion at the same time (Dual drivers and Receivers) ; Easy to set-up and initialize; Operating speed: 120kbit/s ; ±30-V Input Levels ; Operating current: 8mA ; Available in 16-pin PDIP, SO, SOIC packages more

                • Q: Where can I find MAX232 pin description details?

                  A: The MAX232 is a dual driver/receiver that includes a capacitive voltage generator to supply MAX-232 voltage levels from a single 5-V supply. Each receiver converts MAX232 inputs to 5-Voltage TTL / CMOS levels. These receivers have a typical threshold of 1.3 V, a typical hysteresis of 0.5 V, and can accept 30-V inputs. Each driver converts TTL/CMOS input levels into MAX232-F levels. more

                • Q: How do I use a MAX232 for UART communication?

                  A: UART (Universal Asynchronous Receiver Transmitter) or USART (Universal Synchronous Asynchronous Receiver Transmitter) are one of the basic interface which you will find in almost all the controllers available in the market till date. This interface provide a cost effective simple and reliable communication between one controller to another controller or between a controller and PC. more

                • Q: Where can I find a RS232 to TTL converter tutorial?

                  A: Serial communication at a TTL level will always remain between the limits of 0V and Vcc, which is often 5V or 3.3V. A logic high ('1') is represented by Vcc, while a logic low ('0') is 0V. more

                • Q: How do I choose a RS-232 transceiver?

                  A: Despite the development of newer digital interface standards, the humble RS-232 serial port is still a very popular means of data transfer. Robust and easy to use, the RS-232 interface is still an attractive alternative to the more demanding and temperamental digital interfaces. This application note describes key features and helps the designer choose the right RS-232 transceiver. more

                • Q: Why is the MAX232 used with DB9 connector?

                  A: Mostly MAX232 used in 16-pin DIP package. it consist of 3 major blocks .It can only be powered by 5 volts to make it power supply compatible with most of the embedded systems. First block is the voltage doubler in this ic switched capacitor techniques is used to make the voltage double .Once the voltage is doubled second block will converts that voltage to +10 and -10. The third block consists of 2 transmitters and 2 receivers which actually convert the voltage levels. more

                • Q: How does the MAX232 work?

                  A: RS-232(X) is a communication cable, commonly used for transferring and receiving the serial data between two devices. It supports both synchronous and asynchronous data transmissions. Many devices in the industrial environment are still using RS-232 communication cable. Rs-232 cable is used to identify the difference of two signal levels between logic 1 and logic 0. The logic 1 is represented by the -12V and logic 0 is represented the +12V. The RS-232 cable works at different baud rates like 9600 bits/s, 2400bits/s, 4800bits/s etc. more

                • Q: How do I use a MAX232?

                  A: MAX232 is a widely known IC used for establishing serial communication between Microcontrollers and Personal Computers (PC). This IC is used to convert TTL/CMOS logic levels to RS232 Logic levels during the process of serial communication. Usually a Microcontroller operates at TTL (Transistor Transistor Logic) of about 0-5V whereas a PC works on RS232 standards that is (-25 to +25V). So it is not possible to interface a PC directly with a Microcontroller and this is exactly where a MAX232 IC comes into Play. more

                • Q: How do I connect a MAX232 to a PC?

                  A: Serial communication between the computer and the microcontroller follows the below steps: more

                • Q: Can the MAX232 invert a signal from the serial port?

                  A: You won't find a non-inverting TTL/CMOS to RS232 level translator, because there's no market for such a thing. Developing an integrated circuit design is very expensive, so it won't be done unless there is a substantial clearly identified market. And every TTL-level UART expects the idle "space" to be a logic low "0". If you invert the logic level it won't be able to communicate with RS232 devices. more

                • Q: How do I interface a MAX232 with a microcontroller?

                  A: PIC18F4550 has an in-built EUSART (Enhanced USART) module. The module has additional features like automatic baud rate detection from the conventional UART modules in the PIC microcontrollers. more

                • Q: How can I use a MAX232 for serial communication?

                  A: Serial RS-232 (V.24) communication works with voltages (between -15V ... -3V are used to transmit a binary '1' and +3V ... +15V to transmit a binary '0') which are not compatible with today's computer logic voltages. more

                • Q: How do I connect a MAX232 to a RS232 port?

                  A: RS-232 (Recommended Standard – 232) is a standard interface approved by the Electronic Industries Association (EIA) for connecting serial devices. In other words, RS-232 is a long established standard that describes the physical interface and protocol for relatively low-speed serial data communication between computers and related devices. more

                • Q: How do I check a MAX232 IC?

                  A: The MAX232 IC in turn will convert those 5V signals to +/-12V RS232 signals that the computer can understand through the DB9 port on the back of the computer. Admittedly this can be a bit ugly to setup at first. more

                • Q: Where can I find a MAX232 pinout diagram?

                  A: Max232 has 16 pins. It requires four external capacitors for its proper configuration.Capacitors can range between 8 uf to 10 uf and are of up to 16 volts. Pin names With functions are listed... more
