1 INTRODUCTION
The PROLOGGER is a battery powered data collection system manufactured
by UNIDATA. It is ideal for automatic data collection at remote, unmanned
locations. The PROLOGGER incorporates the latest advanced CMOS
technology and intelligent auto calibration techniques to provide a very
accurate, low cost, programmable data collection system.
Like other STARLOG products the PROLOGGER has a simple robust
construction, is battery-powered, is available at a low cost, and can be
universally applied.
The main features of the PROLOGGER are:
•
Large 512k battery protected storage area.
•
16 bit conversion resolution on all channels - analog and digital.
•
High impedance input channels with large 26 bit dynamic range down to
microvolt resolution.
•
GSM/Cellular and PSTN telemetry support.
•
SDI-12 communications bus.
•
Large four line LCD display.
The PROLOGGER provides an upgrade path for the Model 7000 Macro
logger. It supports all existing applications. The signal pin-out is the same and
existing field terminations can be used.
The PROLOGGER is designed to be operated with the Version 3 STARLOG
Software Support Package (Model 6301).

2 INTRODUCTION
2 PROLOGGER OVERVIEW
This chapter provides an overview of the PROLOGGER’s features, including
its programming and operation.
The PROLOGGER is a major design development in the STARLOG product
range. It has an expanded signal capacity and range, and is easier to program.
It offers 22 input channels, two high speed serial input/output busses and two
outputs. It also provides two power sources for external instruments. The
range of scan rates extends from 125 milliseconds to 5 minutes. See page 14
for a list of operational specifications.

Data and commands are transferred between the PROLOGGER and an IBM
or compatible computer using asynchronous RS-232 serial communications.
All set-up and adjustments associated with range and calibration are
performed in firmware. The PROLOGGER is fully programmable.
The PROLOGGER has a very low power consumption. It is supplied with an
internal battery with a typical life of one year. Data is stored in 512k of low
power CMOS RAM. An internal crystal-based clock provides accurate time
referencing of all recorded data and also controls the adjustable scan rate. The
logger’s only external connections are:
•
A connector (labelled INPUT SIGNALS) for instrument inputs, user
power supplies and controls.
•
A connector (labelled COMPUTER) used for communication with a
computer.
The PROLOGGER and its battery are housed in a small, robust, dustproof
enclosure. Exact hardware specifications are listed in Chapter 3.
2.1 Programming Overview
The PROLOGGER is a microprocessor based device designed to be
programmed using Unidata’s STARLOG Software Package (Version 3).
This package, designed to run on IBM PC or compatible computers, creates
and implements instructions that control the logger.
Through a series of windows , the STARLOG Software Package allows you
to define how and when the PROLOGGER records, what channels to record
and what signal types to measure. These definitions are compiled by the
package into a list of instructions to be interpreted by the PROLOGGER.
The PROLOGGER must be programmed before it will record/log or display
readings.
The STARLOG Software generates a set of instructions to program the
PROLOGGER. These instructions are explained in the STARLOG
Programmer’s Supplement (6201).
UNIDATA
4 PROLOGGER OVERVIEW
2.2 How the PROLOGGER Operates
The PROLOGGER must be “initialised” before it can be used. This is done
automatically when you load a scheme. Alternatively, you can manually
initialise the device (see PROLOGGER Initialisation on page 30). Note that
when delivered, the PROLOGGER is shutdown to conserve batteries. It must
be initialised before use.
The PROLOGGER switches on once per scan. You must specify the scan
rate. It performs three operations each time it is switched on: scanning,
inter-log analysis, and RS-232 comms check. It then switches off. This
sequence occurs every scan interval. It performs a fourth operation, logging,
at an interval you specify. These operations are described below.
n
Scanning
Scan rates, which can be from 125 milliseconds to 5 minutes, determine how
frequently the logger switches on. When it switches on, the logger scans its
input signals. These signals, called the hardware values, are recorded in the
PROLOGGER memory. The hardware values are updated in the logger
memory every scan.
n
Interlog Analysis
After scanning the input signals the logger program performs an inter-log
analysis of the hardware values, storing the analysed values in a different part
of the logger’s memory referred to as the Register. The inter-log analysis
includes: averaging and storing maximum, minimum and raw values. For
example, if a certain channel is programmed to store maximum values of its
input, the logger will check to see if the hardware value is higher than the
value already stored in the Register. If so, it will update the Register. If not,
then it changes nothing and goes to the next instruction. The Register is used
to store data between log intervals.
n
RS232 Comms
When the scan occurs at a log interval, the logger program records data found
in the Register into another part of its memory. Here, the data remains until
the logger is unloaded (or until the entire memory storage space is filled, then
earlier stored data may be overwritten when recent data is logged).
PROLOGGER Hardware
PROLOGGER OVERVIEW 5
2.3 Input Signals
The PROLOGGER has 22 channels for input signals. These are divided into:
•
Sixteen analog channels with 16-bit resolution. These can be in any
combination of up to 16 single-ended or 8 differential voltage inputs ,
These channels accept signals from ±5 millivolts full-scale to ±5.00 volts
full-scale.
•
Two high speed serial ports (bi-directional synchronous, eight 16 bit
channels on each).
•
Four counter input channels (16-bit resolution).
•
Two sense input channels (used for LOG START and SDI-12 signals).
The PROLOGGER has a number of operating modes for its analog inputs.
Analog inputs are available as low resolution (8 bit, a0 – a15) or high
resolution (16 bit, A0 – A15) all with programmable gain settings. (See
PROLOGGER Configuration Table on page 47.)
For more about inputs see Installation and Connection on page 23.
Note:
To save power the PROLOGGER only measures signals on channels
specified in the scheme. If you load a scheme that only specifies a single
channel, the remaining channels are not scanned. If you want to scan signals
on all channels, you must load a scheme that specifies all channels.
2.3.1 Instruments
To complement the PROLOGGER, a range of low power instruments and
sensors is available. They are designed for direct connection to the
PROLOGGER and can use the PROLOGGER’s battery or their own power
supply.
The PROLOGGER has a broad input range. This means that instruments such
as thermocouples, pyrometers, RTDs (like the PT100), strain gauge pressure
transducers, precision thermistors and frequency derived signals can generally
be connected without amplification or signal conditioning.
2.4 Outputs
The PROLOGGER has two outputs and two power sources for external
instruments. The outputs have a wide range of uses, for example they can be
used to set off an alarm or switch on an external device.
UNIDATA
6 PROLOGGER OVERVIEW
The four user power sources described in the PROLOGGER Configuration
Table are:
•
+12 Volts DC unregulated.
•
-12 Volts DC unregulated.
•
+10 Volts regulated (reference).
•
+5 Volts DC regulated, scan synchronised.
2.5 Memory Capacity
The logging duration of the logger depends on the scheme. It is calculated by
the software once the scheme is created (see Scheme Information menu).
The calculation includes the following:
Number of Days = (512 - 8) * 1024 * LI/1440 * 1/LS
LI = Logging Interval (in minutes).
LS = Log Size in bytes.
1024 = The number of bytes in a kilobyte.
1440 = The number of minutes in a day.
2.5.1 Log Size
The Log Size is the sum of bytes used per channel. The bytes used per
channel varies depending on the Log Action (raw reading, totalise to 1 or 2
bytes, etc.) and the capacity of the channel. A counter channel may use from
1 to 4 bytes, a serial channel is usually 2 bytes, and an analog channel may
use 2 bytes (high resolution) or 1 byte (low resolution).
For example: A typical weather station logging raw readings for wind speed
(1 byte), temperature (1 byte), solar radiation (1 byte) and relative humidity
(1 byte) every five minutes in a 512k PROLOGGER would theoretically
record for:
Number of Days = (512 - 8)* 1024 * 5/1440 * 1/4 = 448
2.6 Status Indicators
The PROLOGGER has four LED indicators which flash briefly each scan (5
seconds) to show the status of the battery and logging scheme.
PROLOGGER Hardware
PROLOGGER OVERVIEW 7
2.6.1 Battery Status LEDs
The top two indicators (labelled BATTERY) show the internal battery status
(see Battery Status Indicators on page 20).
2.6.2 Scheme Status LEDs
When the PROLOGGER has been programmed with a Scheme (using
Version 2 Software) the lower two indicators show the status of the Scheme
operation.

2.7 The Display and Keyboard
The PROLOGGER has a 64 character Liquid Crystal Display (LCD) and an
eight key operator keyboard.
The Display may be activated by pressing the ON key. The Display will turn
OFF automatically after a delay of 20 seconds (when no further keys have
been pressed).
While the Display is active, the PROLOGGER is in high power mode and
uses about 100 times more battery power than in normal scanning mode.

2.8 Using the Keyboard and Display
The display shows three lists of useful information.
STATUS LIST Lists information about the status of battery and channel readings
(unscaled).
SCHEME LIST Lists details of the current Scheme composed using the
STARLOG Software V3. This is normally blank unless a Scheme
has been loaded.
CONFIG LIST Lets you adjust some logger configuration parameters (change the
scan rate) and execute some useful commands (such as, setting the
logger to the sleep mode).
Warning:
Saving altered Setup Entries using the Enter key will cause data
stored in memory above 64K to be lost.
2.8.1 Selecting a Display List and List Entry
Whenever the ON, SCHEME or CONFIG keys are pressed, the first entry in
the Status, Scheme or Config list is displayed. The ON key will also turn the
Display ON if not already on.
By pressing the scroll keys, you display the next Entry in the list (
6 DOWN
key) or the previous Entry
(5 UP key).
PROLOGGER Hardware
PROLOGGER OVERVIEW 9
Entries may be one or two lines, therefore the scroll keys will move the
display UP or DOWN one or two lines, depending on whether the Entry is
two lines or not.
2.8.2 Auto Key Repeat
When a key is held down, it automatically repeats. This is a quick way to scan
up or down a list of display entries. Releasing the key stops the repeat mode.
2.8.3 Adjusting a Config Entry
To alter a logger Config Entry, scroll to the desired Entry in the Config List
and use the Adjust keys
34 to adjust the Config Entry to the required
settings, then press ENTER to save the new setting permanently. If you do
not want to save the Config Entry, press any other key (or no keys at all).
Warning:
Pressing the Enter key while displaying a Config Entry with the
message ...use & ENTER on Line 2 will cause data stored in memory
above 64K to be lost.
2.8.4 Commands in the Config List
Some entries in the Config List are simple commands, they do not use the
Adjust keys
34 and they do not cause loss of memory when executed
(when ENTER is pressed). A useful command “TURN DISPLAY OFF” is
the first entry in the Setup List. Therefore, whenever you have finished
viewing the display, press CONFIG, and then ENTER keys.
The display will automaticallyturn OFF anyway after 20 seconds if no keys
are pressed.
2.8.5 Using a PIN# (Password)
The PROLOGGER is fitted with a keyboard and display. This enables you to
configure various functions of the logger without a computer. To ensure that
only authorised users alter the operation of the logger, an optional 4-digit
PIN# (personal identification number) may be entered. The factory default for
the PIN# is 0.
UNIDATA
10 PROLOGGER OVERVIEW
To change this PIN#, turn the display ON and then press CONFIG. Press the
down arrow until CHANGE PIN# appears in the display. Press the left arrow
key to select the digit and then the up or down arrow to alter the digit. Once
you have selected a suitable 4 digit number, press ENTER. It is now
impossible to change important configuration settings until the PIN# is
re-entered.
Once a PROLOGGER has been protected by a non-zero PIN#, you must
re-enter the correct PIN# before altering a configuration via the keyboard.
1.
Press ON to switch the display on.
2.
Press CONFIG.
3.
Press the down arrow until ENTER PIN# appears.
4.
Select the correct 4-digit code (using the arrow keys) and press ENTER.
5.
You can now alter the logger’s configuration.
To change the PIN#, you must enter the old PIN# first. A PIN# of 0 means
that all settings may be changed without PIN# validation (default).
If you forget the PIN#, the PROLOGGER will operate normally but you will
not be able to use the keyboard configuration facility until the PROLOGGER
is returned to UNIDATA for service.
2.8.6 Displaying the Scheme List
The Model 7001 PROLOGGER has a four line liquid crystal display (LCD)
and eight key keyboard.
Using the Version 3 Software you can set-up the PROLOGGER to display
the actual values being recorded by connected transducers. This Scheme
Display List contains information similar to the Scheme Test Mode screen. A
one-line display entry is provided for each Scheme Test Mode entry. Four
entries (lines) are shown on the display at one time.
When you press the up/down scroll keys the display moves up/down this list
one line at a time.

PROLOGGER OVERVIEW 11
To view the readings of each transducer:
The display turns OFF after 20 seconds, if no keys are pressed.
If the instrument being displayed uses a non-linear correction formula (such
as a thermistor or wind direction) then the uncorrected (raw) mV reading will
be displayed without units.

4 POWER SUPPLY
This chapter describes the uses of internal and external power supplies for the
PROLOGGER. It also describes the low battery shutdown feature. The
PROLOGGER is powered by an internal battery. External power sources can
be used as an alternative supplies or to recharge batteries (NiCad and Sealed
Lead Acid only).
A battery must remain connected at all times to protect data stored in
memory. Provision is made for fitting a Lithium back-up battery to protect
memory storage if the main battery is removed or fails.
4.1 Internal Battery Pack
The PROLOGGER is powered by its own internal power supply in the form
of a battery pack (usually supplied with each logger). Alkaline (Model
6910A) and NiCad (Model 6910B) battery packs are available. The battery
pack is located in the base of the logger housing and connected via a
three-way socket to the logger.
The PROLOGGER requires a single battery voltage of 6.5 to 10 V DC.
Battery life varies anywhere from a few weeks up to 2 years depending on the
logging project (see below).
This section covers:
•
Battery life.
•
Battery connections.
•
Battery replacement.
•
Recharging a NiCad battery pack.
4.1.1 Battery Life
The PROLOGGER battery life is influenced by five factors:
•
logger scan rate.
•
logger program run time.
•
External instrument power requirements.
•
Display usage.
