# Making The connections

## Recommended Wiring

### Showstopper 4 Accessory Cable

The cable must have at least 6 twisted pairs (12 conductors) of 20AWG (20/6 STP). Here are a few purchasing options:

* [Quabbin PLTC3-20-8S-1](https://www.automationdirect.com/adc/shopping/catalog/bulk_wire_-a-_cable/process_-a-_instrumentation_cable/pltc3-20-8s-1)
* [Igus CF211-05-06-02](https://www.igus.com/product/1073?artNr=CF211-05-06-02)
* [LAPP 302006STP](https://www.lapp.com/en_US/us/unitronic-300-stp/p/302006STP)
* [MultiCable L8020-6PS](https://www.multicable.com/Customer-Content/www/products/Files/PDF_SPECS/Multi-pair_Electronic_Cable_Unshielded_PVC_Insulated___Jacketed.pdf)

### Network Cable

Each network port requires a dedicated, home run Ethernet connection. Almost any CAT5E or CAT6+ solid conductor cable is acceptable. A foil shield is not necessary, but is also acceptable.

Here are two options:

* Belden 1585A or similar
* Belden 4812 or similar
* Belden 4813 or similar
* Belden 2413F or similar

## PCB Pass Through vs Terminated

Control Connections are made so that you can easily expand your automation system. Each faceplate can be wired as either a “home run” back to the Showstopper Accessory output, or it can be wired in series with other Control Connections or Showstopper Remote E-Stops.

All three terminal blocks, top (J1), middle (J2) and bottom (J3), are electrically bonded, so it does not make a difference which ones are used as inputs versus outputs. Our recommended termination pattern is as follows:

J1: Input from previous connection or Showstopper Accessory output

J2: Output to next connection OR jumpers for final termination

J3: Factory installed Accessory Socket

### Jumper Connections

If the Control Connection is NOT being used as a pass through, there are four (4) jumper wires that need to be in place to allow the E-Stop to function properly.

Pin 1 → Pin 2

Pin 3 → Pin 4

Pin 7 → Pin 9

Pin 8 → Pin 10
