10. ation If this happens with nothing attached to provide counter torque the motor will spin continuously until counter torque 1s applied or power is removed The chance of this unintended rotation occurring can be reduced by using the sensitivity threshold jumpers Due to the difficulty of locating the Cheetah system near the ceiling the Saturn X Commutator is always used with the Neuralynx tether extension which also protects the delicate wiring from damage in a potentially hostile ceiling environment The Neuralynx headstage buffers are able to drive up to 25 feet of tether extension cable with no increase in system noise In most cases the use of the Saturn X Commutator and extension cabling should be transparent to the performance of the system It is suggested however that the power cabling for the Saturn X Commutator be run at least half of one meter away from the tether extension along its entire length in order to avoid conducting power supply noise into the electrode signals This is not a hard requirement but is strongly recommended The flex circuit tether exiting the bottom of the Saturn X Commutator is connected to the headstage tether using the appropriate adapter board The tether and headstage assembly are usually left plugged in after mounting The animal is disconnected and reconnected to the hanging tether and headstage each day Revision 1 0 Saturn X Commutator 02 19 2014 Page 17 7 Optical and Fluid Integration The S
