10.1 Introduction
The USB port allows the user to interface with the transmitter without
the use of a computer. Information is stored on a USB memory stick
and then transferred to a computer for storage or transfer. Note: The
USB port cannot be used for communications between the transmitter
and a computer; it is for use only with a memory stick.
WARNING
EXPLOSION HAZARD - DO NOT USE USB PORT UNLESS IT IS
KNOWN THAT EXPLOSIVE GASSES ARE NOT PRESENT. When
explosive gases may be present, the transmitter door may be
opened only to use the keypad or reset button. Obtain hot work
permit and ensure explosive gasses are not present prior to
performing any other operation.
The USB port and the USB memory sticks are not rated for use in
hazardous areas. Therefore, the assumption must be made that
during insertion, removal, or use of the memory stick a condition could
be created which could lead to the ignition of explosive gasses or
vapors if they were present. Always obtain a hot work permit that
verifies that explosive gasses are not present throughout the time that
the USB memory stick is installed in the Transmitter.
Certain models of the passive sonar meter transmitter have a cover
over the USB port which is located to the right of the LCD display.
The USB port cover is a retained sliding cover that is secured with a
retained screw. To open the cover, loosen the screw until it pops up,
and slide the cover to the right.
When finished using the USB port, remove the USB memory stick,
slide the cover to the left, and secure it again with the screw. This
tool-operable cover is required by certain hazardous area certifications
as a feature which forces the user to pause and consider the
consequences of using the USB stick in a potentially hazardous area.
An interruption in data output from the transmitter to a data control
system will occur when using some of the functions of the USB port
