Important notes

• On circuit diagrams, plugs are displayed as viewed from the back side, the solder side. Chips are displayed as viewed from above; also, see the small semicircular cut for finding the correct orientation. When in doubt, see the corresponding description on the legend page.

Construction

You need the following parts to build this cable:

• Two solderable user port plugs

• A shielded 10-wire or unshielded 11-wire cable of, preferably, at most 2 meters

Solder both ends of the cable onto the user port plugs. You should have the following connections:
