AUXILIARY INTERFACE
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.
With reference to the 9-pin connector of Figure 20, the following pins are used to connect the RS232 auxiliary
interface:
