7. How do we get from here to there?

8. Community/Vendor Joint Standards 1.Connectors: type, pin- outs, signal levels and protocols 2.Modules: size, shape, connector locations, locking mechanisms 3.Enclosures: size, shape, material, connectors, accessories commons.wikimedia.org

9. Conclusion To get to the point where we can efficiently configure, deploy, and service large arrays of seismic stations, we need to develop standards for interconnection and form factor of seismic instrumentation. Those standards should be jointly developed between IRIS and the instrumentation vendors.
