GRABBING THE DATA
=================
Local data storage files must be retrieved manually at the station site. I've
tried to download the files over the Freewave radio, but have not had good
results. As a comment of interest, just so you don't try the same things,
here is what I've tried.
First DO NOT use xmodem to transmit files from the station. It locks the
terminal into never-never land, and can't be recovered from without a site
visit to reset EVE. I've tried "xmodem -stycl METPPF.*" direct to the Compaq
attached to the Freewave. This transmits several files via YMODEM-batch and
doesn't work for beans. Neither does "xmodem -stcl METPPF.208" This is just
regular xmodem, and it doesn't work either. NOTE: transmitting configuration
files via xmodem TO the station seems to work OK.
I've also tried to transmit files in text mode using "type METPPF.207" on EVE.
The file is sent OK, but the Freewave doesn't handle data transmission
too gracefully. The end result is intermingled transmitted and retransmitted
data, some garbled, some not.
About the only hope for sending data OK is to send it in small enough chunks
so that Freewave data retransmissions don't mangle everything beyond
recognition. This is possible using the poll command and giving date, time
and packet count parameters.
For instance: poll001 METPPF 208 23:01:00 12
This would retrieve 12 data packets starting at the requested date and time.
DATA DIRECTORIES ON THE COMPAQ
==============================
If you follow the "ECH" menu system running under Procomm Plus on the Compaq,
data will be stored as follows. The script file
c:\pam Main subdirectory used by ECH. Under this directory is a file
called "eveterm.ini" which contains menu items used in the
script. Also under this directory is a directory for each
project known or setup.
c:\pam\scum Project directory for SCUM (a.k.a. SCMS in more polite
company). This is where the station configuration files live
which are downloaded to EVE.
sta001.dat Station file for site 1. The name of this file is used by ECH
in deciding what stations exist for a project.
c:\pam\scum\log Directory where site visits are recorded.
c:\pam\scum\data_1 Local storage directory for station 1. Similar
directories exist for stations 2 and 3. The data
files are generally called METPPF.### where ### is
the julian day. Note: currently, there is some
possibilty of the ### number becoming goofed up if
the same data file is downloaded more than once.
Procomm will rename the new file to ###+1 which
throws the whole numbering sequence out of kilter.
MOVING DATA TO THE SUN
======================
Use "cocklebur" which has a floppy drive to copy the files from the compaq.
There are corresponding directories on the /data (a.k.a. /asterdata) disk.
/data/ppf/eve_local Directory for PPF files generated from the local
data.
/data/ppf/eve_local/data_1 Corresponding data directory for local data
storage.
Copy the data from the Sparc floppy drive to the proper data directory.
DO NOT convert the files to unix format. This is handled in the script file
described below
GENERATING PPF FILES
====================
After the local data storage is safely on the Sparc in the proper
directories, run the following script.
local_to_ppf ###
The script is located in /rdss/pam/bin, so presuming that is in your path,
you shouldn't have any trouble running it. The ### value is the julian day
to be converted to PPF. This script converts the dos files to unix like
format via an awk routine. NOTE: if you already have an existing PPF file for
the data in /data/ppf/eve_local the eve_file_translator program just appends
the data.
Another script is available to merge the data, but thus far the merge program
seems to leave 200% data recovery or so.
merge_local 950725
Would merged the data and leave the merged data in /data/ppf/merged.
