Got to this just in time...
Here is my earlier question on this same topic.
Link to Separating C7042 APB
Go to the link to JeremyR's thread to see how the connections can be made off the PB.
It is the C7030 but the same could be done with the C7042 and an extra pair of power cables.
Cheers!
EDIT: note that someone else used USB connectors for the date and another type of plug for the power. Maybe someone else can link to this.
Found it! Here is the posting link... USB data links
Also see his picture at: Modified Powerbase (yeah, it is a C7030 but the principle is the same for the APB.... the USB connections look so cool, but cannot find the parts, so will go with the RJ45 connector myself)
Here is another link to the APB separation.... Separating powerbase for APB
Cheers!
