Kontex System Adapter
Adapters into the XDAQ chain, remapping a probe-side connector onto an X-Series or Omnetics-32 output — including a Neuropixels J2 dock.
What it connects
Two configurations, both remaps onto the XDAQ chain:
| input | output |
|---|---|
| Neuropixels J2 dock | Omnetics-32 or X-Series SmartLink |
| XDAQ-side connector | Omnetics-32 or X-Series SmartLink |
The Neuropixels configuration is the one that matters for a mixed lab: a Neuropixels probe reaches XDAQ acquisition on the same rig, with the same clock, as the rest of the chain — so a group running both probe types is not running two acquisition systems side by side.
NeuroNexus does not make Neuropixels; this adapter is how a probe you already run enters the chain.
The failure this part causes
Two connectors that mate are not two connectors that agree. A remap adapter deliberately changes which pin carries which channel — that is what it is for — so the probe's site-to-channel map does not survive the adapter unchanged. Nothing about the physical fit tells you this has happened. The recording looks fine; the channel order is different from the one in your analysis script.
Confirm the site-to-channel map through the adapter before the first real recording. It is a five-minute check against a known signal, and it is the single most common reason a chain that plugs together produces a map that does not match the probe drawing.
