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.
