It consists of 6 pins. - RS-232 - RS-232 connect two DTE devices or computers using DB25 pin connectors. Functional Description: In addition to defining electrical characteristics, RS232 specifies the signals used in serial cable pinouts and serial ports. The most recent version of the protocol is known as RS232C. This shows that we are able to communicate with an HC-05 Bluetooth module using USB to serial FTDI cable. After that configuration window will appear, select the COM port and set the baud rate to 9600 and COM port number which you noted in earlier steps. In mixed applications, a 9 to 25 pins converter can be … Appendix 5 Cable Pinouts Console and Auxiliary Ports (RJ-45) To identify the RJ-45 cable type, hold the two ends of the cable next to each other so that you can see the colored wires inside the ends, as shown in Figure 5-5. RS-232, when compared to later interfaces such as RS-422, RS-485 and Ethernet, has lower transmission speed, short maximum cable length, large voltage swing, large standard connectors, no multipoint capability and limited multidrop capability. This timeout is used to flush the remaining data from the receive buffer. Serial interfaces cables and converters scheme pinouts A serial cable is a cable used to transfer information between two devices using a serial communication protocol. In practice, only one serial communication channel with accompanying handshaking is present. But mostly four pins are used to connect UART based devices with the computer through this FTDI cable. Common Ground - Zero reference voltage level for all the control signals. DB25 V.24 pinout and signals (ALT A connector) Fig.5. We do not need to worry about these USB pin details. It has negative polarity. Category:Converter Cables You also have the option to opt-out of these cookies. All the clock signals on serial cable pins 15, 17, and 24 of the COM port pinout are for synchronous communications only. To use this FTDI cable, we need a device driver which is available to download freely  from FTDI website. RTR (Ready to Receive) - DTE is geared up to receive data coming from DCE. Also, connect GND a pin of FTDI with GND pin of HC-05. Open the device manager and find the name of the COM pin in the ports list. DTE is the acronym for Data Terminal Equipment and DCE represents Data Communication Equipment. This black color console window will appear. It will show you all the FTDI devices connected with your computer. For this to work, the Transmit (TxD) pin of one device needs to be connected to the Receive (RxD) pin of the other device, and vice versa. This cable has been designed to use the least possible bandwidth of HOST or Hub controller. After downloading and installing Putty, connect the FTDI cable with your computer.
