Guralp Systems CMG-CD24 - Manual (Page 13)

Operator's Guide
The first few status blocks will consist of the CD24's start-up messages,
including its software revision number and the data streams selected
for downloading and triggering.
Later blocks give information on the GPS system (number of satellites
visible, the location of the GPS antenna, time synchronization status,
etc.) and the baud rates in use for each channel.
For more information on SCREAM! refer to the user manual available
from the Güralp Systems' website: www.guralp.com
2.3 Setting up the Ethernet or wireless interface
CMG-CD24 digitisers with Ethernet or Wireless features installed use
an embedded Lantronix Wi-Port module to provide the network
interface. Configuration of the Ethernet or Wireless interface is made
using the Lantronix' DeviceInstaller utility for Microsoft Windows,
using a DHCP server or the via the serial port. You will need a PC with
a network or wireless interface installed or an RS232 connector,
You may find it easiest to gather together all the Wi-Fi hardware before
taking it into the field and configuring it from a local wireless-enabled
PC.
There are two types of wireless network topology supported by the
Wi-Port.
●
Infrastructure networks need additional hardware, such as
wireless access points and routers, to work. Any host on the
wireless network will communicate with the access point or
router, which manages all the connections and ensures data are
transmitted correctly. This device may also provide
connectivity to the Internet or your local network.
●
Ad hoc networks can be set up with no additional hardware.
Each host on the wireless network attempts to communicate
directly with the other hosts. Ad hoc networks are easy to set
up, but they are only suitable with a small number of hosts. In
seismic networks, infrastructure mode is normally preferred,
since sensors do not need to communicate with each other. For
more information see Appendix F – Setting up an “ad hoc”
wireless network on page 113.
