Types of Cable and Example Connections

When using an RS-232C interface, different cables are required depending on the type of device to which you are connecting (computer or modem,

etc.). Check the requirements of the external device and select either a straight-through or crossed (null modem) cable as appropriate. If special

treatment of the signal lines in the connector is required, ensure that this is done in accordance with the specifications.
