Reference Channel Configuration (Gen. 4)

To use the Probe Reference site, follow these instructions: 1. Do not cut the wire loop jumper.2. Cut both Wire 1 and Wire 2. This prevents ground loops from forming.3. Reference channels R1 and R2 connect to the Probe Reference site. Reference channels R3 and

R4 can be connected to an external reference via Wires 3 and 4.

To disable the Probe Reference site, follow these instructions: 1. Cut the wire loop jumper. Do not cut the reference wires yet. 2. With the wire loop jumper cut, each of the reference wires can be connected to an external reference

source.

The H64 Gen. 4 package has 1 insulated wire loop jumper (see above) and 5 colored insulated wires. The Ground wire is green. Wires 1, 2, 3, and 4 correspond to the Reference pins on the Om-netics connectors (Wire 1 connects to R1, etc.). Please read fully before making your desired changes - it may not be possi-ble to reconnect the wire loops once they have been cut.

Below are 2 possible wiring configurations. You must choose one option and act accordingly or a ground loop may form.

To use the Probe Reference site, pursue only one of the following 4 options: a) To feed the Probe Reference into all 4 Reference pins, cut Wires 1 and 4, twist Wires 2 and 3 together, and leave the

jumpers uncut.b) Cut Wires 1 and 2, and leave the jumpers uncut. Channels R1 and R2 serve as the Probe Reference, and 1 wire reference

can be fed to both channels R3 and R4.c) Cut Wires 1, 2, and Wire Reference Jumper 2. Channels R1 and R2 serve as the Probe Reference, and Channels R3 and R4

serve as independent wire references (via Wire 3 and Wire 4, respectively).d) Cut Wire 1 and both Wire Reference Jumpers. Channel R1 serves as the Probe Reference, and Channels R2, R3, and R4 serve

as independent wire references (via Wire 2, Wire 3, and Wire 4, respectively).

The H64 Gen. 3 package has 3 bare wire loop jumpers (see above) and 5 white insulated wires. The Ground wire is designated with black shrink wrap. Wires 1, 2, 3, and 4 correspond to the Reference pins on the Omnetics connectors (Wire 1 connects to R1, etc.). Please read fully before making your desired changes - it may not be possible to reconnect the wire loops once they have been cut.

Below are 7 possible wiring configurations. You must choose one option and act accordingly or a ground loop may form.

To disable the Probe Reference site, cut the Probe Reference jumper, then take only one of the following 3 actions: e) For two wire reference signals, leave the Wire Reference jumpers uncut. Wires 1 and 2 feed into Channels R1 and R2,

and Wires 3 and 4 feed into Channels R3 and R4.f) For three wire reference signals, cut Wire Reference Jumper 1. Wires 1 and 2 (Channels R1 and R2) serve as independent

wire references, and Wires 3 and 4 (Channels R3 and R4) serve as one combined wire reference.g) For four independent wire reference signals, cut all jumpers.

Wire Loop Jumper

To use only the Probe Reference site, follow these instructions: 1. Do not cut the wire loop jumper.2. Cut both reference wires (Wire 1 and Wire 2). This prevents ground loops from forming.3. All the connector reference channels (R1, R2, R3, and R4) connect to the Probe Reference site.

To use an external headstage reference, follow these instructions: 1. Cut the wire loop jumper. Do not cut the reference wires yet. 2. With the wire loop jumper cut, connector channels R1 and R3 now connect to the Probe Reference,

and connector channels R2 and R4 can be connected to an external headstage reference with Wire 2 (closer to connectors).

3. To prevent a ground loop from forming, cut Wire 1 (closer to probe).

Wire 1

Wire 2

The H64 Gen. 2 package has 1 bare wire loop jumper (see above) and 3 bare wires. The Ground wire is designated with black shrink wrap. Wire 1 (closer to probe) is connected to channels R1 and R3. Wire 2 (closer to connectors) is connected to channels R2 and R4. Please read fully before making your desired changes - it may not be possible to reconnect the wire loops once they have been cut.

NeuroNexus recommends taking one of two reference configuration options. You must choose one option (see below) and act accordingly or a ground loop may form.

IMPORTANT: Check our catalog to see if your probe model has a probe reference (PR) site.If your design has a PR site, and you plan on using it:1. Cut Wire 1 (see above)2. Make sure that the PR site is completely implanted3. Reference channels R2 and R4 (see below) now function as the Probe Reference

If you do not intend to use the PR site, cut Wire 1, connect Wire 2 to your external reference source, and use reference channels R1 and R3 as your external reference channels.
