Connections and Cables¶
Connection types¶
Headstage Link¶
The headstage link allows fast data communication between an ONI compliant headstage and the PCIe host board. This connection is formed by a single coaxial cable for each attached headstage (or other ONI compliant hub, such as a UCLA Miniscope V4). This connection also provides power to the headstage from the PCIe host board.
The headstage link can be formed directly between the host PCIe board and a headstage. Alternatively, a headstage link can include an active commutator and/or breakout board between the PCIe board and headstage.
Connectors used for headstage link:
PCIe host board: MMCX connectors
Breakout board: MMCX connectors (to link to PCIe host) & SMA connectors (to link to commutator or headstage).
Commutator: SMA connectors to link to both breakout board and headstage.
The Headstage-64 & Neuropixels-1.0 Headstage: Hirose X.FL-PR-SMT1-2(80) X.FL coaxial socket connector.
Lighthouses¶
Audio (Lighthouse A) to Audio (Lighthouse B) - to synchronise lighthouses (only necessary for V1 Basestations)
Power cables for lighthouses (x2, provided with lighthouses)
Commutator link¶
Computer (USB) to commutator (micro-USB) cable, to power the commutator & provide orientation data.

Connecting MMCX¶
The MMCX connectors at the end of these cables can easily break off if used incorrectly. When connecting or disconnecting, hold the connector itself instead of pulling at the cabling.
