RJ11 to RS232 wiring diagram RJ11 - RS232 The RJ11 RJ11 RJ11 - Registered Jack 11 - is used for the landline telephone. It is an international standard that is used to connect the landline telephone to the Telecommunications network. RJ11 uses a 6-slot connector. In it RJ11 has 6 slots (positions) and two conductors, the standard is written 6P2C. The information transmitted on the line can be digital (DSL) or analog. jack is interesting, as the manufacturer has chosen to have a symmetrical pin layout, just like with the MMJ connector on DECconnect systems and the RJ45 RJ45 RJ45 - Registered Jack 45 - is also called an Ethernet cable. This cable can be straight or crossed depending on its use, its connections follow precise color codes. It is the most common cable for network connections for example to the Internet. This type of cable has 8 pins of electrical connections. Its connector is called 8P8C connector (8 positions and 8 electrical contacts). jack in the Yost standard. A symmetrical pin layout allows two DTEs (data terminals) to be connected directly without the use of a modem or other DCE data communication equipment. The original RS232 RS232 For a serial line information arrive at regular intervals (synchronous) or at random intervals (asynchronous). Between a transmitter (DTE) and a receiver (DCE) wiring is right. RS232 cables can be connected in series. In configurations where 2 DTE are directly connected, a cable of cross linking or \Null-Modem\ should be used. This cable has female connectors at each end. wiring was developed for 25 pins. The vast majority of RS232 RS232 For a serial line information arrive at regular intervals (synchronous) or at random intervals (asynchronous). Between a transmitter (DTE) and a receiver (DCE) wiring is right. RS232 cables can be connected in series. In configurations where 2 DTE are directly connected, a cable of cross linking or \Null-Modem\ should be used. This cable has female connectors at each end. applications use only 3 links : TX, RX, and GND. 9-pin RS232 RS232 For a serial line information arrive at regular intervals (synchronous) or at random intervals (asynchronous). Between a transmitter (DTE) and a receiver (DCE) wiring is right. RS232 cables can be connected in series. In configurations where 2 DTE are directly connected, a cable of cross linking or \Null-Modem\ should be used. This cable has female connectors at each end. connectors are commonly used. In mixed applications, a 9 to 25 converter can be used to connect sockets of different sizes. Two other signal contacts, RTS and CD, are sometimes used when interfacing to modems or to RJ11 RJ11 RJ11 - Registered Jack 11 - is used for the landline telephone. It is an international standard that is used to connect the landline telephone to the Telecommunications network. RJ11 uses a 6-slot connector.
