While on the subject of the DLINK radio...
<R38> B. The radio power feed must be connected via the 5V converter (model # TBJ12DK025Z) to the marked 12 Vdc supply terminals located at the end of the PD Board (i.e. the terminals located between the indicator LEDs, and not the main WAGO connectors along the sides of the PD Board). No other electrical load can be connected to these terminals (please see the 2011 Robot Power Distribution Diagram posted online at www.usfirst.org/frc/kitofparts for wiring information).
I just discovered rule this yesterday afternoon while looking for something else. Ay-yi-yi! We've been running ours directly off the 12Vdc terminals. It still works but I hope we haven't somehow damaged it. Maybe everybody else but us knew this but you might want to check your robot to be sure that the converter is being used to provide the correct voltage to the radio.
