 Notes on Hydrostatic Probes
 These probes use the hydrostatic pressure of water to measure water depths
 in various environments. The hydrostatic pressure of water is dependent on
 the depth at which the water is measured and the atmospheric pressure.
 The maximum expected change in atmospheric pressure due to the change in
 weather is approximately 10kPa (100hPa) which is 1% of 1000kPa (100m head
 of water). The 1% is within the accuracy of a hydrostatic pressure transducer.
 Hence for this type of transducer it is important to relate the measurement
 against atmospheric pressure. For water depths of less than 100 metres
 (1000kPa) a gauge type transducer (Model 6542 or Model 8007WDP) fitted
 with vented cable (e.g., Model 6600J) is used. For depths greater than 100
 metres you can use an absolute type transducer without vented cable.

     Neon Server Applications Software
      Model 2301A/2302A

     The Neon Applications software is a
     suite of software and documentation
     which allows clients to set up their
     own Neon system on existing server
     hardware, or new server hardware
     located at the client’s premises. The
     software is provided on a licence
     basis and allows clients to set up a
     measurement system using Neon
     Remote Terminals/loggers in the field
     and have these communicate with the
     central server. Services to install, set
     up, commission, and support the Neon
     server are provided. Annual software
     maintenance and application support
     agreements are available.
     The Neon Applications software uses
     leading technologies to provide access
     to remote instruments in the fields via
     standard internet access methods and
     protocols.
     The Neon Applications software
     provides remote data collection and
     logger-scheme updating for Neon
     Remote Terminals (NRTs) and any
     connected loggers (e.g., Starlogger,
     Prologger, Starflow Instrument,
     Precision Water Level Instrument)
     from any internet access point in
     the world. The system has been
     specifically designed for environmental
     data collection and automated
     meter reading. Low cost and very
     low power consumption with a high
     level of on-line access, diagnosis, and
     reconfiguration have been key design
     targets.

                       standards in accuracy and input
                       range. It is packaged in the robust
                       enclosure so familiar to Starlog users
                       with twice the accuracy, eight times
                       the resolution, and sixteen times the
                       dynamic range. It is the ideal upgrade
                       from its predecessor the 7000 Macro
                       Logger. All Prologger analogue and
                       digital inputs are processed with 16
                       bit resolution. The sixteen inputs now
                       support the following ranges:
                       ±5.000V (155uV/bit resolution)
                       ±500mV (15.5uV/bit resolution)
                       ±50mV (1.55uV/bit resolution)
                       ±5mV (155nV/bit resolution)
                       The superior accuracy of the new
                       design means that input voltages will
                       be converted to better than 0.05%
                       of full scale over the full operating
                       temperature range, and 0.1% in the
                       5mV range.
                       The Prologger’s increased memory
                       capacity means you can acquire more
                       data or increase the period between
                       downloads. The unit also includes all
                       the familiar Starlog features such as
                       SDI-12 instrument support, modem

                                        in a wide range of applications, the
                                        Starlogger is a high performance,
                                        upward-compatible replacement for
                                        the original STARLOG Portable Data
                                        Logger (PDL). The Starlogger is easy to
                                        program and offers wide signal capacity
                                        and range.
                                        All Starloggers feature eight (10-
                                        bit) analog channels, four (16-bit)
                                        counter/frequency channels, and 2
                                        (16-bit) HSIO lines with 8 channels
                                        each. Their memory capacity is 512K
                                        CMOS RAM, enough storage for many
                                        months of recording. They also provide
                                        two power sources for external
                                        instruments. The range of scan rates
                                        extends from 125 milliseconds to 5
                                        minutes.
                                        The Starlogger uses standard
                                        asynchronous RS-232 serial
                                        communications to communicate
                                        with an IBM PC or compatible
                                        computer or a modem connected to
                                        a telemetry system.
                                        Starloggers are completely portable.
                                        They contain an internal battery
                                        supply for one year of normal
                                        operation. Starloggers are fully
                                        programmable using the STARLOG
                                        programming language.

                                  The Display STARLOGGER adds the
                                  convenience of a display and keyboard
                                  to the functions of the STARLOGGER.
                                  The 32 character, two-line LCD
                                  enables you to view signal readings
                                  while recording data. Battery, memory
                                  and program status can also be
                                  displayed.
                                  With the eight-key keyboard you can
                                  control the display, make adjustments
                                  to the STARLOGGER’s configuration,
                                  and give simple commands. Remember
                                  that frequent use of the display will
                                  reduce battery life.

HSIO Serial Digital Interface Standard
HSIO implementations allow up to
sixteen compatible instruments to
be connected to a single Unidata
data logger.
Each instrument requires one 16 bit
channel of bandwidth allocated to
the HSIO implementation. Model
6004 Starloggers have 2 buses with
8 x 16-bit channels per bus, Model
7001 Prologgers have 2 buses with
8 x 16-bit channels per bus, and the
8001 Microloggers have 1 bus
with 4 x 16-bit channels per bus.
All these instruments support the
HSIO interface.
Electrical Interface
The electrical interface consists of
a five wire bus system, allowing a
master (data logger) to interrogate
up to 16 slaves (instruments). Signal
levels are TTL compatible. They are:
SYNC
Generated by the master. It is used
to indicate to the slave that a bus
read is about to begin (active high).
COMMON
Signal ground.
CLOCK
Generated by the master. Clocks-
in data sent from the slave to the
master. The number of clock pulses
generated depends upon the number
of slaves connected to each bus.

     When systems are developed, the
     customer’s specific requirements are
     considered and the configuration
     is decided based on technical and
     commercial criteria. One key issue
     is maintainability and field support,
     especially for remote systems. The
     Neon Applications Software allows for
     remote configuration and adjustment
     of logger / Neon Remote Terminal
     configuration, which can be very cost
     effective, minimizing or eliminating
     the need to travel to remote logging
     sites to reconfigure and diagnose the
     equipment.
     Systems can be set up inside customer
     defined enclosures, with the only
     connection necessary being a field
     termination strip or panel, which
     simplifies the field installation process.
     When Systems are considered, there
     are some key issues to consider:
     •	 Instrument	selection,	deciding	on	
        the most appropriate measurement
        method.
     •	 Site	power	selection,	deciding	if	
        a sealed lead acid battery with
        solar panel support is best, or
        an alternative power source, for
        example a bank of high capacity
        lithium batteries may be best.
        Unidata has battery calculator tools
        available to decide on the best
        battery option for such systems.
     •	 Instrument	enclosure	selection,
