Abstract

An interface cable comprising a plurality of changeover switches for selectively connecting various lines of the interface cable. It is characterized in that the plurality of changeover switches are provided between RS232C connectors connected to the ends of the interface cable. The changeover switches can interchange an SD line and an RD line with respect to each other and can selectively connect an RS line, a CS line, a DR line, a CD line and an ER line between the RS232C connectors.

Claims

1. An interface cable comprising:

a connecting cable having multiple lines;

at least two RS232C connectors connected to opposite ends of said cable, said multiple lines of said cable establishing a connection pattern between said at least two RS232C connectors; and

a plurality of changeover switches provided between said RS232C connectors for selectively changing said connection pattern with respect to at least a part of said multiple lines,

wherein said plurality of changeover switches can interchange an SD (BA for EIS) line and an RD (BB for EIS) line with respect to each other and can selectively connect an RS (CA for EIS) line, a CS (CB for EIS) line, a DR (CC for EIS) line, a CD (CF for EIS) line and an ER (CD for EIS) line between the RS232C connectors.
