Earthworm v6.2 running on Windows 2000. ######################################## Earthworm download and documentation see http://folkworm.ceri.memphis.edu/ew-doc/ link to software download see section 1.4 Before anything else, you have to read 2.1 Installation and Configuration. The installation is pretty simple it is mainly to copy the files to your hard disk. The files are in e.g. c:\earthworm. Earthworm programs are in c:\eartworm\v6.2 directory if you run version 6.2. All executables are in c:\eartworm\v6.2\bin For your setup files; create c:\earthworm\run_xxx\params, and for log files c:\eartworm\run_xxx\log. Here xxx can be name of the site or whatever you want. Download run_test.zip for an example of setup. Paths and startup info ###################### Edit ew_nt.cmd in params dir. (use ew_nt for Windows system) Set ew_installation to INST_WILDCARD. Set path all the path according to your installation. Set time zone to Central European Time (Norway). TZ=CET-1 Setup In dir params make the .d (config files) and .desc (description files). (desc files not always nescessary) for the modules you want. There are sample configuration files of all the modules in the documentation. My system ########## I have set up a basic earthworm system, reading data from Par8Ch digitizer (www.symres.com). WaveServerV pick up data (also have ringbuffer). Other modules connect to WaveServerV for data. I connected the WaveViewer to the WavveServerV. WaveViewer has a grapical user interface. If you do not see the traces. See log files for error messages. Maybe to much dc offset, choose bias in the menu to center traces. Triggers are saved in user defined dir in SeisAn format. Traces are continuously plotted in gif images. LISS server setup. Possible with manual event dump. The driver for ADC I downloaded from symres web site. The data are collected by the WaveServerV modules. This module also store the data in a ringbuffer called tank. The tank name and location are defined in the configuration file of WaveServerV, one for each channel. Module used. srparxchewsend ADC driver statmgr status messages (e.g. heartbeats) wave_serverV Wave server wave_viewer GUI program to view wave forms carlstatrig Event trigging for a station carlsubtrig trigging for newtwork. These two modules working together. trig2disk Writes the event trigger to disk (e.g. in SeisAN format) waveman2disk Dump manual events. You define start time and duration. heli_ewII Helicorder emulator. Makes a HTML file with gif images of traces. ew2liss LISS server. Other PC can connect with LISS client and receive data. See www.liss.org copystatus WAVE_RING HYPO_RING copy status messages used from the run_test example. Probably not needed here. copystatus PICK_RING HYPO_RING here copy from PICK_RING to HYPO_RING. Most module are ok to setup. Just remember: 1) Check that always installation is INST_WILDCARD (in .d / .desc). Some example used INST_UNKNOWN /INST_MENLO. (if you want to have your own registrated installation contact USGS) 2) Check that module id is registrated in earthworm.d (else make a new entry). The modules trigger module (carlstatrig, carlsubtrig) was a little tricky to setup, due to error in documentation. The station list file (.sta) has to have ONLY one space between SCN identifier. Not as in the documentation with several spaces. In carlstatrig.d the station list file (.sta) should be stated without ". In carlsubtrig a link to the file trig_id.d is given. This file was not included in the binary distribution. I had to download the source distribution. And copy the file to the params directory. Starting earthworm. ################### Open command window. Go to params directory. Set paths by running ew_nt (only needed once for a new command windows) Then write commando startstop. (startstop_nt.d defines which modules starts up and name of config files, and if module shall run in its own command window) Jose 21/2-2005
