The WSDA-RGD (with internal GX3 inertial sensor) is configured to produce the following messages on startup.

GPS Data (1 Hz):

  • UTC Time
  • LLH Position
  • NED Velocity

AHRS Data (100 Hz):

  • Euler Angles

From this output the WSDA logs:

GPS (1 Hz):

  • latitude
  • longitude
  • height above ellipsoid
  • height above MSL
  • horizontal accuracy
  • vertical accuracy
  • speed

AHRS (100 Hz):

  • roll
  • pitch
  • yaw

The WSDA-RGD does not log any data until it gets a valid time, if it is set to get time from GPS only it will not log any output from the GX3 until the UTC timestamp from the GX3 is valid, even though the GX3 is producing valid AHRS data.

This data is not user configurable and is not available as a live stream through LiveConnect.

All LORD MicroStrain wireless sensor nodes, wireless base stations, and wireless sensor data aggregators are shipped from the factory with their radio frequency set to channel 15 (2.425 GHz).

This channel setting was established during 2012.

Previously all wireless products were set to channel 25 (2.475 GHz).

If you are mixing new nodes and base stations with older nodes and base stations, please be cognizant of these different channel settings.

The Node Discovery function of Node Commander will help you sort out which nodes are on what channels; Node Discovery is channel independent and allows the base station to communicate with any node, no matter what channel it is on

Sampling methods such as synchronized sampling, low duty cycle, network broadcast, etc. require that all nodes are on the same frequency so you will want to insure that you have adjusted the channels settings of the nodes to suit.

The LORD MicroStrain® WSDA-Base-101-LXRS Wireless Analog Output Base Station supports all data acquisition sessions between wireless nodes and host computers including Synchronized Sampling (both Continuous and Burst modes), Armed Datalogging, Datalogging, Streaming and Low Duty Cycle. As an integral feature, the WSDA-Base-101-LXRS has an analog output back panel that supports analog data acquisition equipment (DAQs). Up to 8 sensor channels from one or multiple wireless nodes can be fed into a DAQ with simultaneous digital feed into a PC, or into a DAQ with the PC removed (stand-alone configuration). Each channel on the back panel has a 0 to 3 volt range representing the particular sensor’s full scale output. In some environments and with some equipment, the 0 to 3 volt range is not appropriate; many types of programmable logic controllers (PLCs) and DAQs have only current loop inputs, are therefore incompatible with voltage output sensors, and require a 4 to 20 mA output range to operate. This technical note demonstrates how to convert the 0 to 3 volt output to a 4 to 20 mA output using a third party converter and assumes familiarity with the WSDA-Base-101-LXRS, LORD MicroStrain wireless nodes and Node Commander software.

In FINITE sampling, the user sets a total number of samples to be taken which equates to a time period.  Because the sampling rate per second is known, the user can adjust the number of samples to be taken to determine how long the sampling period will be.

In CONTINUOUS sampling, the user does not set the total number of samples and therefore does not set the time of the sampling period.  By selecting CONTINUOUS sampling, the user is instructing the system to sample data until the user manually stops the sampling (via software), the power is cycled, the on-board datalogging memory is full, the battery dies, the power fails, etc.

LORD MicroStrain® Wireless Sensor Networks provide several data acquisition modes including:

  • Synchronized Sampling
  • Armed Datalogging
  • Streaming
  • Duty Cycle

See the particular wireless node for specifics.
