= WAM User Lines = == Pinout / Information == **Note: The User Lines are not USB 2.0 compatible** The WAM and Wrist have 4 “user” lines that start at the backplate of the base of the WAM and exit as a wiring harness at the opening in the top plate of the Wrist. The 4 lines are not 4 continuous wires, but consist of multiple wiring harnesses strung together through several connectors and traces on a PCB. The wiring is a mix of 20 and 24 AWG wire and is shielded for approximately half of its length. [http://web.barrett.com/support/WAM_Documentation/WAM-UserWiring.pdf| WAM User Wiring]
