Here is a link to the diagram to make the cable yourself.
It is not a 1 to 1 cable as a lot of people think .

You could use a DB9 to RJ45 converter and put the pins in the db9 plug to correspond to the
diagram ,when you buy the plug the pins are not in the db9 you have to push them in what hole you want them in, making this the easiest way to make the cable up to the diagram in the link .
As for the cable on ebay unless it says it is for the EQ6 the pinout will not be the same as this diagram.
Made a sample cable up with RJ45 plugs at each end one is upside down! so when you plug it into the hand controller pin 1 is on the right when you plug the other end into the converter pin 1 is
on the right.
Now using a Multimeter you can work the pins out to the diagram link.
The rolls of cable in the picture are 4,6 and 8 strand flat cable.
For this cable you can use the 8 wire flat cable.
