Chapter 7 - Configuring Serial Communications
7.1 About Serial Communications
The Trillium Compact has an integrated Web server that is accessible using a standard Web
browser and the RS-232 serial interface. The sensor web page can be used to retrieve sensor
information, access state-of-health information and control features, and to configure the
sensor.
The simplest way to connect to the sensor’s web page is to use a Nanometrics digitizer, such as
Centaur (see
"Connecting through a Nanometrics Digitizer" below
.) The web page is accessed
through the Web interface of the digitizer. The Web Interface is a series of Web pages that
retrieve information about the seismometer, access state-of-health (SOH) information and
control features, and allow you to configure the seismometer. See
If you are not using a Nanometrics digitizer, connecting to a Trillium Compact seismometer
requires an IP connection over a Serial port. Most modern PCs, laptops, and handheld devices
do not include a physical serial port. In addition, currently supported Microsoft Windows
operating systems do not support Serial Line Internet Protocol (SLIP) connections.
Nanometrics has developed a simple, low-cost appliance that converts Ethernet to SLIP to
allow IP communication with sensors from PCs or laptops. Alternatively, advanced Linux users
can build their own SLIP appliance. For more information about the Nanometrics SLIP
appliance, instructions on building your own SLIP appliance, and other methods of accessing
your Nanometrics smart sensor web interface, refer to the Nanometrics technical note
Accessing Your Nanometrics Smart Sensor Web Interface (18105)
, or go to
7.2 Connecting through a Nanometrics Digitizer
Nanometrics digitizers, such as the Centaur, support the Web interface of the Trillium
Compact, allowing you to access the Web-based features of the seismometer through the Web
interfaces of those instruments. This allows you to access the unit remotely, even while it is in
service, without requiring a breakout cable and a SLIP connection on a co-located computer.
