CMG-DCM Data Communications Module

The options on the Data transfer – DSS page are:

datatransfer.dss.server : Set this to

on to run the server; off to disable

it.

datatransfer.dss.server.port : The port number on which to listen for
incoming DSS packets. The default is 9000.

datatransfer.dss.server.password : The password all clients should use

when registering with dssserver.

datatransfer.dss.server.window : The number of DSS intervals to use

for travelling windows (used in the PGA and MMAWINDOW data
types). The default is 10.

datatransfer.dss.server.options : Any additional options to send to the

DSS server process (for advanced usage.)

Remember to click

Save changes before you browse away from the

page, if you want to keep the changes you have made.

The DSS server will not immediately use the new options, because

clients may still be connected. You will need to restart the DSS server
at a convenient time. Clients will have to reconnect to the new

instance of dssserver before they can continue receiving data.

To restart the DSS server, browse to the Tools – Process Overview

page and find the entry for the dsserver process. Click the Restart

link in this entry.

5.4 CD1 (CD1.0) Sender

Continuous Data Format, CD1.0, is a standard method for sending

seismic data over a TCP/IP network. The DCM module can send data
in CD1.0 format to a specific CD1.0-compatible device or NDC.

Some installations of the DCM have multiple CD1.0 senders. In this

case, there will be several

sender pages, all with the same options.
