HS 36 Figure 7 8 Analog Signal Breakout The Signal BNC Input is used to input a function generator test signal Note that this signal is first reduced by 1000 1 by two resistors This is usually a sine or square wave A 1 volt input will result in a 1 millivolt signal to the input of the HS 36 inputs Neuralynx Inc 105 Commercial Drive Bozeman MT 59715 Phone 406 585 4542 Fax 406 585 9034 www Neuralynx com Revision 1 1 support Neuralynx com 10 27 2010 Page 9 ae 2 S eS Reference Connector 20 O eS a s4 S1 A1 gt A8 gt A16 B9 gt B16 The HS 36 Connector is where the HS 36 is connected When attaching the HS 36 pay special attention to the orientation of the connectors The alignment pins will prevent backwards connections You can also use the FBlack Part Number0 printed on the connectors to indicate the orientation they should both be on the same side S1 thru S5 controls the 1000 1 reduced signal to various ManksO or sets of signals on the HS 36 connector These switches are arranged as SI Signal to HS 36 Al thru A8 S2 Signal to HS 36 A9 thru A16 S3 Signal to HS 36 Refl thru Ref4 S4 Signal to HS 36 B1 thru B8 S5 Signal to HS 36 B9 thru B16 The 1000 1 reduced signal is connected to one pole of each of the 5 switches Each switch will control the input signal to the above described banks When each switch is in the UP position it will cause the reduced signal to be connected to the respective HS 36 bank
