The 16 channel switchable acute headstage has an 18-pin DIP connector that can
be used with standard high impedance metal electrodes. The pinout of the SH16
matches the wiring of NeuroNexus electrodes, allowing direct connection to the
headstage. TDT recommends connecting electrodes to an 18-pin DIP socket and then
connecting the socket to the headstage to protect the headstage from unnecessary
wear and tear.
Important! When using the headstage with the NeuroNexus probes, keep in mind that there may
be several versions of the probe. Check the NeuroNexus Website for pin diagrams.
Also, see MCMap for a description and examples on how to re-map channel
numbers.
Connection Diagram
When using the SH16/SH16-Z with a microstimulator system, connect the system as
shown. The diagram below shows a system configuration featuring the RZ5 BioAmp
Processor, an MS16 Stimulus Isolator, and RA16PA Medusa PreAmp. Connections are
much the same when using the RX7 in place of the RZ5.
Switchable Headstage Operation
When using the SH16/SH16-Z switching headstage with an RZ5 or RX7 processor
and an MS4/MS16 Stimulus Isolator, TDT recommends using the SH16_Control
macro to set stimulation channels and mode of operation. Based on the macro
settings, all necessary control signals are sent from the base station to the headstage
via the MS4/MS16 Control output port.
