Instructions for Installing the eDAQ MicroStr3DMGX1 Module
September 15, 2009
Note - The following must be
performed whenever the eDAQ system firmware is updated. For the
eDAQ v3.13.C release, proceed as follows.
- If applicable, update the eDAQ system
firmware. The procedure for this is detailed in the Installation
Instructions provided with each eDAQ release.
- Using a web browser, bring up the start page of
your eDAQs web interface. In the Location (URL) bar of your
browser, type "http://" followed by the IP number of your
eDAQ. For example, an eDAQ with SoMat default settings could be
reached at "http://192.168.100.100".
- On the eDAQ home page, click on the "Custom"
item in the eDAQ menu list.
-
In the Custom menu option, select the "Install New
Module" option. Use the "Browse" button to locate the correct
version of the file based on the type of eDAQ.
-
eDAQ-Plus, eDAQ-Lite - The file
"MicroStr3DMGX1_LP_v3_13_C_build_302" is in the "modules" subdirectory in the distribution CD or
ZIP file.
- Click on the "Install Custom Module" button
and the eDAQ will proceed to install the module. Click on OK and
there will be a new list item associated with this module. The
initial status of the module is disabled. To use the module,
click on the Enable option in the Action column.
- Next, go to the System menu and select the option
"Reset eDAQ". The eDAQ will reset. Wait for the LEDs to indicate
that the reset is complete (i.e., red and green on, amber
off).
-
To test out the installation, start up TCE, go to
the Hardware Setup window and click on the Query button. A list
of the hardware modules will be presented. Double click on the
line for the MPB Serial Bus card type. TCE will present a dialog
window for setup of the MPB Serial Hardware Interface. If the MicroStr3DMGX1 module was correctly
installed, there will be a "MicroStr3DMGX1" entry in the
Hardware Interface combo box, and a "MicroStr3DMGX1" entry in
the Data Base list box. Click on the OK button to enable the
MicroStrain channels to be defined and used in TCE.
-
The MicroStr3DMGX1 channels are handled in essentially the
same way as all other Serial Bus (and Vehicle Bus) channels
are handled in TCE. In brief, follow the steps below to setup
a data recording session using MicroStr3DMGX1 channels in TCE.
-
Configure the Serial Bus hardware interface for
MicroStr3DMGX1 channels as described in Step 7 above, if
you have not done so already. Note that active querying is
not supported for MicroStr3DMGX1 channels.
-
Go to the Transducer and Message Channel Setup window, and
click on the Add button. TCE presents a list box of the
different type of transducer and message channels that are
supported. Double click on the MPB Serial Bus entry, and
TCE will present the full list of channels defined in the
"MicroStr3DMGX1" data base.
-
Select any or all of the channels in this list, and hit
the OK button. TCE will load all of the channels into the
Transducer and Message Channel Setup window list. All of
the new channels added will be highlighted. This is a good
time to change the sample rate if so desired. To do so,
click on the Edit button, and TCE presents a set of Group
Edit options. Select the Query and Sample Rates option and
hit OK. A small dialog window is presented to allow you to
choose a new sample rate.
-
To record data, you must select one or more data
modes. For example, to store time history sequences, go to
the Data Mode Setup window and click on Add. TCE presents
a list of supported data modes. Select the Time History
option, and TCE responds with a dialog window for defining
this data mode. Select all of the MicroStr3DMGX1 channels,
and then assign some ID tag, and then hit OK.
-
Save this setup file (using the Save As option under the
top level File menu item), and this test is now ready to
be Initialized (using the Initialize Test option under the
top level Test Control menu item). From then on, use the
various Test Control menu options (or the ToolBar once you
are familiar with it) to start and stop test runs and
upload test data.
Note on cables: Connect the MicroStr3DMGX1 unit serial
cable to a DB9 Male - DB9 Male gender changer. Connect the
gender changer to a DB9 Null Modem adapter. Connect the Null
Modem adapter to the eDAQ serial cable.
The MicroStr3DMGX1 MPBSer module initializes the 3DM-GX1 unit
into continuous mode for the message "Send Gyro-Stabilized Euler
Angles and Accel and Rate Vector", command byte 0x31. The
message used is not configurable. The RS-232 serial baud rate is
set to 38400 bits per second and is also not configurable.
The available channels from the module are as follows:
