Wire colors are not part of this, you can do with them whatever you want. RS232 Pinouts Signal Ground. … RS232 port related links - RS232 to RS232 connect two DTE devices or computers using DB9 pin connectors. - Serial port interface serial port interface description. RS232 Pinout Below is the pinout of a typical standard male 9-pin RS232 connector, this connector type is also referred to as a DB9 connector. Byte1[3:0]=0x1~0x07. It’s normally abbreviated SG.

RS232 (aka EIA232/TIA232) describes the electrical (voltage levels) and mechanical (connector type and pinout) aspect of the interface. The signal ground provides this return path. Each of the pairs are twisted together. Like David says, you can't even be sure that black is ground. RS-232 (parfois appelée EIA RS-232, EIA 232 ou TIA 232) est une norme standardisant une voie de communication de type série.Disponible sur presque tous les PC depuis 1981 jusqu'au milieu des années 2000, il est communément appelé le « port série ». Sur les systèmes d'exploitation MS-DOS et Windows, les ports RS-232 sont désignés par les noms COM1, COM2, etc. To maintain reliability on Ethernet, you should not untwist them any more than necessary (about 1/4 inch). RS232 defines both the physical and electrical characteristics of the interface. All the signals used in a serial port need a return path. There are totally 7 Timers, this value is used to decide which Timer is selected. The single ground signal is the common return for all the other signals on the serial interface. Its absence will prevent serial communications entirely. Communication Wiring Color Codes Cat 5 & 5e Network Color Codes for RJ-45 Ethernet Plug Eight-conductor data cable (Cat 3 or Cat 5) contains 4 pairs of wires. Each pair consists of a solid color wire and a white and color striped wire.
