User Manual for AML Oceanographic’s Micro SVT Sensor

capillary tube to eliminate pressure effects while still allowing fast time response. The
temperature sensor uses a dedicated RISC microprocessor to control the sensor excitation
and communicate with the data logger electronics.
The data logger and power control electronics use a RISC microprocessor running at 19.6
MHz to control the sampling and power as well as to communicate with the sensors and
communications interface board.
The communications interface board is normally an RS-232C board. Optional
communication boards include RS-485 and TTL. Through the communications board, the
instrument will on power up, automatically detect baud rates from 2400 to 38400 baud. The
baud rate is automatically determined when the sensor receives an <
ENTER
> or <
RET
>.
The data output may be configured to display either unprocessed integers, or computed
engineering values. The Micro SVT Sensor has the option of sampling on command or
monitoring continuously with programmable sampling rates. The latter is not available with
the binary protocol. The RS-485 binary protocol option allows the instruments to be
individually addressed permitting multiple instruments to be daisy-chained together.

THE USER
This manual has been written with the following assumptions:
• The user has had some exposure to MS Windows compatible computers, and is
moderately computer literate with a working knowledge of computer operation and
terminology.
• The user is familiar with the operation and function of standard communications packages.
While it is possible to operate the Micro SVT Sensor without these qualifications, some
computer experience will greatly assist the user to pass through the learning curve more
rapidly.
