PC INTERFACE
Interface with a PC is accomplished by connecting the VT3 to a PC USB Port using the USB
Interface Cable provided. The same Cable is used for Upload and Download.
The software program is on the OceanLog CD provided, together with a USB Driver. The
program's Help section serves as the User Manual and can be printed for personal use.
The Settings Upload program is used to check the VT3's existing Settings and for entering
settings into the VT3. The Data Download program is used to retrieve Data that was
sampled during dives and stored in the VT3's memory.
The VT3 checks for an External Access request once every second while in Surface Mode.
Checks are not made if the unit is WET. For a connection to be made, the Interface Cable
is plugged into the VT3's Data Port and plugged into a PC USB Port. To establish the
connection, the PC program must be running asking 'RUTHERE'. When the connection is
made, all segments of the VT3 appear on the display until completion of the Upload or
Download operation.
• The VT3 reverts to the Surface Mode Main screen after completion of the Upload or
Download operation, or after 2 minutes if no PC action was taken.
SYMBOLS AND ALPHA NUMERIC GRAPHICS
The upper line of digits on the LCD screen is used to convey alpha Messages such as Day
of the Week, Operating Modes, items being Set, Gas and Transmitter identification,
Altitude level, and Alarm identification. At times, the second line is also used to display
alpha numeric graphics such as PO2 and On/Off. The FO2 setting of a selected Gas will
appear in the lower line.
