can be linked to another host computer or an external system. This interface is mainly used
for SC4000 configuration through Genius™, the multilanguage software tool. Diagnostics
and program downloading can be performed from this interface.
Connections can be made to a PC or Laptop using a straight through cable or a USB-RS232
