DCE (Data Communications Equipment or Modem) and the DTE (Data Terminal Equipment or teleprinter).As a result it is always best to be aware of the complications that exist.As a result it may often be necessary to experiment a little.
![]() Similarly The DTE receives data on pin 3, whereas the DCE transmits on pin 2. Rs232 Db9 Pinout Serial Data CableIt also saves considerable complications by not having to work out which wires to cross over in the serial data cable. Some of the simpler systems just send the data without any hard wired handshaking and as a result the serial data cables required for this are very simple. Rs232 Db9 Pinout Software Codes SuchThese systems may utilise the use of software codes such as X-ON X-OFF, ACK, NAK, etc to provide the handshaking that is required. These systems require serial data cables that incorporate the transmit and receive data lines as well as an earth line. According serial data cables for these systems require the additional lines to be incorporated into the serial data cables for them to operate correctly. Some cables could have more connections for additional functionality, but these are rarely used. This can be time consuming, but often provides a good cable provided a few precautions are adopted. And connectors. This is exceedingly easy to implement, but may not be as robust or provide the screening needed to protect the integrity of the transmitted data over any distance. Most connectors have options for adding strain relief and this should be adopted. Thoroughly inspect and electrically check the cable before use. There are many types of sleeve that can be sued and these will give protection as well as keeping he wires together. If there are no complications, i.e. DTE to DCE connection, a serial data cable will simply require one to one connections of the required pins.
