The voltage of Logic "1" (Mark) is between -3VDC to -15VDC, while the Logic "0" (Space) is between +3VDC to +15VDC. The data transmission starts with a Start bit, followed by the data bits (LSB sent first and MSB sent last), and ends with a "Stop" bit. The graphic above illustrates a typical RS-232 logic waveform (Data format: 1 Start bit, 8 Data bits, No Parity, 1 Stop bit). RS-232 Signals RS-232 Logic Waveform (8N1) They cross transmit and receive data signals between the two sides and there are many variations on how the other control signals are wired, below is one of them: Straight-through (DB-9) A crossover (null-modem) cable is used to connect two DTE directly, without a modem in between. modem), all signals in one side connected to the corresponding signals in the other side in a one-to-one basis. Reverse or back view of male connector for Female Connector.Ī straight-through cable is used to connect a DTE (e.g. RS-232 Pin outs (DB-9)Ī male DB-9 connector viewed from the front. Note: The result for a DB-25 Connector is reversed (Please refer to DB-9 to DB-25 conversion table below). If the voltage is on Pin 2, then it is a DCE device. Use the simple way below to confirm: Measure Pin 3 and Pin 5 of a DB-9 Connector with a Volt Meter, if you get a voltage of -3V to -15V, then it is a DTE device. A modem is a DCE.ĭTE normally comes with a Male Connector, while DCE comes with a Female Connector. DCE stands for Data Communication Equipment.
DTE and DCEĭTE stands for Data Terminal Equipment. RS-232C, EIA RS-232, or simply RS-232, refers to the same standard defined by the Electronic Industries Association in 1969 for serial communication. Step 1: Understand RS232 Connection & Signals If you have a chance to test your RS232 devices with the 232Analyzer software, you should be able to control your RS232 devices in a short period of time.
