The DT ShapeArray (DTSAA) logger from RST Instruments is designed to measure a single ShapeArray sensor. It is a small form factor data logger powered by a single lithium primary battery. The DT ShapeArray logger allows ShapeArrays to be incorporated into a wireless, or stand alone, data collection system. The DT ShapeArray reads ShapeArray sensors configured in low power mode. If configured with an RSTAR radio, the DT ShapeArray will transmit data wireless to an RSTAR hub.
NOTE: Only Measurand ShapeArrays with serials numbers greater than 350000 support the low power mode required for use with the DT ShapeArray. The power mode of a ShapeArray can toggled between regular power mode and low power mode using the SAARecorder application which is included Measurand's SAASuite. Please ensure your ShapeArray is in low power mode prior to configuring the DT ShapeArray.
Step 1 - Connect the ShapeArray and Insert Battery
Open up the DTSAA enclosure. Insert the ShapeArray cabling through the cable gland at the bottom of the DTSAA. Connect the wires in the ShapeArray cabling to the appropriate terminals within the DTSAA and insert the Li-SOCl2 3.6 V D-cell battery. If the battery has already been inserted from the factory, remove the pull tab that is isolating the battery from the terminal connection.

Step 2 - Connect the DTSAA to a Computer
Once the ShapeArray has been connected to the DTSAA and the battery inserted, connect the DTSAA to a computer using a mini-B USB to USB A cable.

Step 3 - Open DT Logger Host
To proceed you will need to have RST's DT Logger Host software. This can be downloaded from the RST web site. Once DT Logger Host is downloaded and installed, launch it. Wait for it to connect to the DTSAA. This will be indicated by the port and status icons in the bottom left corner of the window turning green.

Step 4 - Verify Delay Settings
On the Connections tab, select the Options button, and then the Advanced menu item.
Figure 4. Connections -> Options -> Advanced
In the Advanced dialog, click on the Adjustments button. In the Adjustments dialog, ensure that the Delay Before Scan (s) setting is set to 0.5. Click OK to save the configuration and continue.

Step 5 - Discover the ShapeArray
On the DT SAA tab, click the Discover Arrays button in the ShapeArray Discovery section. If prompted to proceed, click Yes to continue. Once the array has been discovered, click the Reconnect button to continue.

Step 6 - Define a Collection Interval
At this point, if you are using the DTSAA as a standalone logger, you only need to configure the logging interval. This is done through the Logging tab by modifying the various fields in the Interval section and then clicking the Apply Settings button.
Figure 7. Set the logging interval on the Logging tab and click Apply Settings
NOTE: It is a good idea to verify that the ShapeArray configuration is working as expected. To collect a reading immediately, navigate to the Monitor tab and click on the Get Data button. This will save a reading to your computer's your Documents\Multichannel folder.
The DTSAA is now setup to be a standalone logger. When you are ready to collect data directly from the DTSAA, select the Status tab and click the Collect Data button.
Figure 8. Collect all data stored on the DTSAA from the Status tab with the Collect Data button.
Once the data collection is complete, the raw data files will be saved in your computer's Documents\Multichannel folder by default.

NOTE: If the DTSAA is to be incorporated into a wireless RSTAR network, it will need to be paired to an RST RTU and the program will need to be generated for the RSTAR hub logger. Please contact RST Instruments for more information on this configuration.
