2.3 Blackrock Quad IDC 10 Adapter Reference Selection The dip switches on the Quad IDC 10 Adaptor are used to select the reference for each bank of channels.

5 2.3 Blackrock Quad IDC 10 Adapter Reference Selection The dip switches on the Quad IDC 10 Adaptor are used to select the reference for each bank of channels. Each bank of channels can use its own reference, the reference from any of the other three banks, or the external reference. External GND External Reference A B C D X G Figure 4: Reference Selection Position 1 ON: Selects reference from Bank A Position 2 ON: Selects reference from Bank B Position 3 ON: Selects reference from Bank C Position 4 ON: Selects reference from Bank D Position 5 ON: Selects external reference (X) Position 6 ON: Shorts reference to ground (G) *Only one position should be ON for each reference selection switch NOTE 1: Refer to Figure 3 for the locations of Banks A, B, C and D. Page 5

6 2.3.1 Reference Selection for Macro Contacts Use GND as reference for all macro contacts. In order to select reference for the macro contacts, it will be necessary to connect an external ground to the green touch-proof GND connector on the Quad IDC 10 Adapter. To use GND as reference, set the position 6 switch on Banks A and B to the ON position. Refer to Figure 3 and 4 for the location of the reference selection switches Reference Selection for Micro Contacts The micro contacts use the macro contacts as reference. Each bank of channels uses a different macro contact as its reference Bank A Reference = CH01 Macro Contact Bank B Reference = CH12 Macro Contact Bank C Reference = CH02 Macro Contact In order to select the CH01 Macro Contact as the reference for the micro contacts on Bank C, set the position 3 switch on Bank C to the ON position. To select the CH02 macro contact as reference, set the position 1 switch on BANK C to the ON position and to select the CH12 macro contact, set the position 2 switch on Bank C to ON. NOTE: Only one reference should be selected for each bank at a time. 3 Micro/Macro Electrode Mapping The following table provides channel mapping between the DIXI 5128-PROTO 20 electrode cable and the Blacrock Neural Signal Processor (NSP).
