If you don’t have a rack, it can also sit on a desk or on top of a Stagehand Controller - just be sure it is secured. ## Making the Connections The Showstopper 4 Accessory Hub will need to be connected to your Showstopper system before it can be used as intended, as it will not function on its own. It must be connected to a Showstopper 4 Base, along with a few other connections as explained below. ### Input Power Connect the IEC power cable to the back of the Showstopper 4 Accessory Hub and plug into any standard 120VAC power source. The power connection must be constant. Loss of power to the Showstopper 4 Accessory Hub will engage the E-Stop and stop all movement to any Stagehands in the system. We recommend adding in a Battery Backup to avoid issues in the case of a power loss. ### Ethernet The Showstopper 4 Accessory Hub includes an Ethernet connection in order to communicate E-Stop status to Spikemark. The Ethernet connection will accept a Neutrik Ethercon connector (#NE8MC-B) or any standard RJ45 connector. ### Showstopper Accessory Connections The Showstopper 4 Accessory Hub has one (1) Accessory input and six (6) Accessory output connections. The Showstopper 4 Accessory cable must be 20awg, 12 conductor twisted pair cable. Non-twisted pair cable will not work. We use IGUS Chainflex CF211-05-06-02 for our cables, but any manufacturer will work. Here are a few 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) The Showstopper 4 Accessory output provides dual channel E-Stop signals, CAN Bus (E-Stop Status) communication, and +24VDC power for the Showstopper Consolette and Pendant. All of these signals are combined into a single 21mm x 21mm (3A) 12 pin locking connector. There are several manufacturers of these types of connectors, our favorite is from MENCOM. The inserts are the CQF-12 (for the receptacle - output) and CQM-12 (for the plug - input).

The system architecture is extremely flexible. Showstopper 4 Accessories can be daisy-chained, or home runs to the Showstopper Base or Showstopper Hubs. Each Showstopper Accessory output must be terminated. The outputs can be terminated internally (the Console, Consolette and Pendant are terminated) or with a terminating plug. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.creativeconners.com/docs/showstopper/showstopper-accessory-hub/installation.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
