Using the Web Interface
7.1 About the Web Interface
The Trillium Compact has an integrated Web server that is available using a standard Web
browser and the RS-232 serial interface (see
). This interface is provided through either the serial connector or the
main connector. Use the Web interface to retrieve information about the unit, access
state-of-health information and control features, and to configure the unit.
The home page of the Trillium Compact presents links to other pages. The following
sections describe these pages:
Section 7.3 “Seismometer Control”
7.2 State-of-Health
The SOH page provides information that indicates the health and status of the unit. Click
the
Refresh
button to update the page with the current information.
The sections on the page are as follows:
Mass Positions (Range ±4.000)
The mass position values for the U, V, and W axes. These values range from 0 V
(perfectly centred) to approximately ±4 V (when decentred and not able to respond
to ground motion). The mass position output on pin R of the connector is an analog
voltage that corresponds to the axis that is decentred the most. For example, if the U,
V, and W mass positions are +0.230 V, -2.200 V, and +1.024 V respectively, then the
analog mass position output would be approximately -2.200 V.
For mass position readings under ±2.5 V, the table cell is green, for readings from ±2.5 V
to ±3.5 V, the cell is yellow, and for readings above ±3.5 V, the cell is red.
Ensure that the proxy server is disabled when using a Web browser with a Trillium Compact.
