All CBX800s have an RS232 auxiliary interface available on the 9-pin connector below, which can be linked to
another host computer or an external system. This interface is mainly used for CBX800 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 converter.
