Our HS-16-mux is a multiplexing headstage that records from up to 16 individual electrodes. The physiological signals are digitized at the headstage and sent down the twisted pair digital tether to the multiplexing inputs of the Digital Lynx SX-M.
Below are important notes for recording from HS-16-mux:
- The HS-16-mux AD Channels do not match with the EIB AD Channels. A custom Cheetah Configuration File is required to properly map the AD Channels.
This image shows the AD Channel on the EIB-16 and which AD Channel this maps to on the HS-16-mux. NOTE: If interfacing an implant other than EIB-16, keep in mind the AD Channel mapping on the input to the headstage.
- The HS-16-mux must be connected to the Digital Lynx SX before the system is powered ON. Otherwise, the system won’t recognize that a multiplexing headstage is present.
- The HS-16-mux contains an internal AC current waveform generator that can output 9 different current amplitudes at 1kHz. The AC current waveform generator is controlled by sending specific commands to the Digital Lynx SX, which are then routed to the multiplexing headstage. These commands can be sent through a NetCom interface or simply through a Cheetah Configuration File. The channels electrode impedance at 1kHz can be approximately calculated using Ohms law.
This command, and more like it, can be found in the Cheetah Reference Guide.
The notes and features detailed above can also be reviewed in the HS-XX-MUX Instructions for Use manual.
