# Earthworm Modules:
RockToEW Overview

(last revised November 5, 2008)

The Rock-to-EW module provides a data relay from a Kinemetrics-Rockhound-compatible instrument to the USGS Earthworm software package. The module is written in Java and runs on the instrument hardware itself, emulating an Earthworm "export_generic" module, and providing a TCP/IP listen port for external "import" programs to connect to. To install or update the Rock-to-EW module in a Rockhound-compatible instrument:

> - Copy the "RockToEW_update.jar" file into the " /usr/rock/SMARTSDist/injar" directory on the instrument
> - Rename "RockToEW_update.jar" to "update.jar"
> - Reboot the instrument

Once installed, the RockToEW module needs to be added to the digitizer's layout, and the module's parameters configured. See the instrument's manual (Kinemetrics p/n 300715) for details on how to add and configure modules. See the RockToEW description for details on the module and its parameters.

The RockToEW source code is archived in the "src/src.zip" file. Once unpacked, the "mkdist.sh" script or "mkdist.bat" batch file may be used to rebuild the module from source. A local installation of the Rockhound software package is required (for the library 'jar' files). Note that (at the time of this writing) the Rockhound platform uses a Java 1.3 runtime environment, so all module code features must be compatible with Java 1.3.

RockToEW was written by ISTI and funded by Kinemetrics, Inc.
