Downloading Data Files
To download a data file:
1. Setup the communication parameters between TRDI Toolz and the ADCP.
2. Wake up the ADCP by pressing the
3. Click Tools, Recover Recorder.
4. TRDI Toolz sends the RY command to recover the data. The RY command uploads the entire con-
tents of the CompactFlash memory card via the serial interface to a host computer using the
standard YMODEM protocol for binary file transfer. The data is transferred to the host and stored
as binary files.
5. Once the data has been recovered, the recorder can be erased by sending the command RE ErAsE.
This command is case sensitive. Once erased, the data is not recoverable.
Compass Post Calibration
This section applies to the WHII electronics only. See How do I know if I have WH or WHII
electronics? to determine what electronics are installed in the system.
Compass Post Calibration corrects for heading errors due to hard and soft iron effects in the Workhorse
reference frame during the deployment. Often, post calibration will provide results more reliable than
when only a pre-deployment calibration is performed.
Some example scenarios where the post calibration is
•
The Workhorse is installed on a mooring and rotates freely sampling the magnetic environment
throughout the deployment.
•
The magnetic properties of the installation changed after the pre-deployment calibration. For ex-
ample, a battery pack was added, or the Workhorse was installed in a mounting frame con-
structed of a ferrous material.
•
The Workhorse was subject to magnetic interference during the pre-deployment calibration.
Post calibration will not be effective
•
The magnetic interference is not in the Workhorse reference frame. The Workhorse is deployed
adjacent to a large metal structure like a bridge or ship for example.
•
The magnetic properties change over the deployment.
