On the other hand, for the mating DCE connector, socket #2 receives data into the DCE and socket #3 transmits data out of the DCE. In the case of DB25 connector, for DTE, pin #2 was for transmission of data out from the DTE and pin #3 was for receipt of data coming into the DTE. The specification actually went on to say all DTE connectors would have male pins and be wired in a certain fashion and all DCE connectors would have female sockets and also be wired in a certain fashion. As you might guess, teletypes, terminals and computers are considered to be DTE and things like modems are considered to be DCE. DTE (Data Terminal Equipment) and DCE (Data Communication Equipment).Īn RS-232 communication link was expected to have a piece of DTE at each end with DCE in the middle. So I used another pin to change it to female at DTE.Ī long time ago (at least in computer hardware terms) the folks who came up with the RS-232 communications specification decided that there would be two broad classes of equipment. It was mentioned in the manual that interface should connect with DTE(computer) with female, but I end up with both male at the computer. I'm not sure how to check whether hardware working properly or not.
