To download a data file:

2. Wake up the ADCP by pressing the
3. Click Tools, Recover Recorder.
4. TRDI Toolz sends the "r?" and "m?" commands to verify the recorder type and then uses the RY or
MY command to recover the data. The RY and MY command uploads the entire contents of the
recorder via the serial interface to a host computer using the standard YMODEM protocol for bi-
nary 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.
Opening a Data File with Velocity
When a *.PD0 (pd zero, not the letter o) file is opened, Velocity creates a matching *.pdv and *.pjv files
depending on the options selected. The *.pdv file is used to process data and the *.pjv file contains the lat-
est information about user selections for processing parameters and data displays.
The original *.pd0 file is never changed, moved, or overwritten.
To open a data file:
1. Start Velocity.
2. Click the Home button (
3. Click the Options button and select the options. Data averaging is on by default.
4. Do one of the following:

• With the Start menu selected, on the Starting actions area, click Open a data file button.
• Click the Open menu button.
5. After the file is opened, a mini preview of the data file will display at the top of the Velocity screen.
Click the preview to switch to the session (if other files are opened).
