Serial Interface Cable and V.24 adapter

The V.24 adapter cable is used to connect PCs directly. An electronic controller incorporated in
the cable matches levels. Without level matching, V.24 operation is not possible.
For connecting printers or modems, differently wired adapters are connected between the 9-
pole SubD socket of the cable and the interface of the relevant device.
