Cable Options

NOTE: On long cable runs, cable resistance causes a drop in voltage at the end of the cable run. 
Ensure the appropriate power and current for your device is available at the device at the end of the 
cable run. Heavier gauge cable reduces this effect.

NOTE: Keri does not recommend hot-plugging a Reader, RIM, or 4x4 into an NXT controller. 

Remove power from the controller prior to connecting these devices.
