NOVUS LogBox-DA Electronic Data Logger Instruction Manual
Introduction
LogBox-DA is an electronic data logger with two input channels: one analog and one digital. The values measured by these channels (data) are stored in the logger electronic memory and later sent to a computer in table or graphical form. It is possible to export them for use in programs such as spreadsheets.
To configure the logger and view or download data, you must use the NXperience software. When you configure it, you can set the start and end mode of the recordings, the parameters of each input, among other functions.
LogBox-DA provides an auxiliary electronic switch, which can be used in series with the power supply of external instruments, connected to the logger. With this feature, you can configure the logger to close the switch and power these instruments only at the instant of acquisition, extending the battery life of the external instrument.
MEMORY CAPACITY
- 64 k Model: It allows up to 64,000 logs, The memory capacity is divided between the enabled channels. When there are two enabled channels, each has half of the available memory. When a single channel is enabled, it has all the memory at its disposal.
The available memory capacity is indicated on the identification label,
attached to the housing of the logger.
Figure 1: Identification label
INPUT SIGNALS
Channel 1 (IN 1) counts digital electrical pulses, which can be of the following types: Voltage Pulse, Dry Contact (switch) or Open Collector, according to the configuration made.
Channel 2 (IN 2), in turn, measures analog electrical signals, which can be of the following types: 0-20 mA, 4-20 mA, 0-50 mV, or 0-5 V, according to the configuration made.
Note: For the channel 2, in addition to performing the configuration via software, you must properly position the internal jumper.
DATA ACQUISITION (LOGGING)
Data can be acquired by means of two different modes.
For channel 1, which counts electrical pulses, the recorder counts the number
of pulses received in a programmed period. At the end of each period, the
measured count value is stored in the memory of the logger, creating a log.
The maximum number of logs that can be stored depends on the memory capacity.
For channel 2, the logger can: 1) Perform a single measurement within a defined period and log the value read or 2) perform ten measurements in this period and log in memory the average of the values read or log the minimum value or maximum value measured.
OPERATION
In the NXperience software, which must be previously installed on the computer to be used, you can configure logger operation mode (see LOGGER CONFIGURATION item). To read or change this configuration, you must use the IR-LINK3 Communication Interface (see IR-LINK3 OPTICAL INTERFACE item).
Once the device has been configured and the electrical input connections have been made, it is ready to measure and log the signals applied to the input channels. Status indicators display the current condition of the logger.
STATUS INDICATORS (LEDS)
The Status Indicators (see Figure 2), located on the front of the logger,
serve to indicate the current operating condition of the device:
LOG Indicator (Logging): If it is waiting to begin acquisitions (stand-by) or
after a series of acquisitions has been completed, the LED blinks once every
four seconds. If it is performing acquisitions, it blinks twice every four
seconds.
AL Indicator (Alarm): This indicator informs about alarm situations. Whenever
an alarm situation occurs, it blinks once every four seconds. It remains in
this condition until a new setting is applied to the logger.
Figure 2 – LEDs and IR communication
CHANNEL 1 MULTIPLICATION FACTOR
Channel 1 was designed to count electric pulses from liquid flow meters (litters per pulse, for example). You can set the amount of liquid that corresponds to each received pulse. You can also easily change the adopted flow rate unit.
Although adapted for flow rate, it is possible to monitor other quantities. In this case, you must disregard the expression l/pulse (liters per pulse) in the Sensor Factor field.
SOFTWARE NXPERIENCE
You must use NXperience software to configure and download data from LogBox- DA. To install the software, simply run the file NXperience_Setup.exe, available on our website.
RUNNING NXPERIENCE
When you start NXperience, the home screen will appear:
Figure 3 – NXperience home screen
Next, at the bottom of the screen, you must click on the button to indicate
the serial port to be used by the IR-LINK3 Optical Interface, which must be
connected to the computer USB:
In the example above you should select the option “USB Serial Port (COM3)” and
click Ok. After that, simply click on the Configure button and then on Read
Device to perform the connection process.
Note: This manual provides basic information on how to configure the
device. For more specific information about other features, please refer to
the NXperience manual, available on our website.
IR-LINK3 OPTICAL INTERFACE
To configure, monitor, or download data from the logger through the NXperience software, you must use an IR-LINK3 Communication Interface (purchased separately).
IR-LINK3 acts as an intermediary between the device and the computer being used and allows you to transmit and receive data from the logger via infrared signals.
The driver will be installed during the NXperience installation process. Once this is done, IR-LINK3 will be recognized whenever it is connected to the computer.
LOGGER CONFIGURATION
To configure the logger, IR-LINK3 Communication Interface must be connected to the computer being used.
IR-LINK3 must be directed constantly towards the logger communication window
(see Figure 5) and kept at approximately 15 cm:
Figure 5 – Interface directed to the logger
According to the instructions defined in the NXPERIENCE SOFTWARE item, you
must click the Read Device button to start the communication between the
recorder and the software. Then, the general settings screen will be
presented:

LOG
Log Interval: Allows you to determine the time interval (hh:mm:ss) between acquisitions. At the end of this period, the data will be saved in the memory of the logger.
Estimated Time: Based on the “Interval” of the acquisitions and the number of programmed acquisitions, it informs you how long it should take the logger to perform all the programmed acquisitions. Available if the Memory Mode is set to “Full Memory” mode.
External Battery Switch: Allows you to set the time interval that the logger takes to turn on the electronic switch before each measurement. This time cannot exceed half the time between measurements (limited to 10 seconds).
MEMORY MODE
Circular Memory: The logger performs acquisitions continuously. Once the logger reaches maximum memory capacity, the oldest data will be overwritten.
Full Memory: The logger performs acquisitions until the available memory capacity of the logger is reached.
START MODE
Immediate Start: Allows to start the acquisition process right after sending the configuration to the logger.
Date/Time: Allows to start the acquisitions at a defined date and time.
Digital Input: Allows to perform acquisitions while the digital input is
triggered (closed) and to stop acquisitions when the digital input is disabled
(open).
Start Button: Allows to start the acquisitions using the Start button.
Daily: Allows to start the acquisitions daily and at a previously defined time.
STOP MODE
Memory Mode Only: Allows to link the stop mode to the memory mode of the logger. That is, the acquisitions will be interrupted if the memory limit is reached (if Full Memory mode is set) or will never be interrupted (if Circular Memory mode is set).
Date/Time: Allows to stop the acquisitions at a defined date and time.
After a specific number of logs: Allows to set a number of acquisitions
that, when reached, will stop the acquisition process. Daily: Allows to stop
the acquisitions daily and at a previously defined time.
FINALIZATION
Once the settings have been made, you must click the button to open the
finalization screen:
Figure 10 – Finalization
From this screen you can send and start logs, save the configuration to file, download data from memory, and start, pause, or stop the logging control.
ELECTRICAL INSTALLATION
Only the input channel connections and the internal electronic switch (when used) are required. The electrical power supply is provided exclusively by the internal battery.
For the IP65 model, input and external trigger terminals are available internally. To make the connections, you will need to open the housing.
For the IP67 model, the terminals are outside the housing, at the connectors shown in Figure 11.
IP65 MODEL
In the IP65 model, the connections are made internally. To access the terminals and the configuration jumper, it is necessary to remove the cover from the logger.
The connection wires enter the logger through the cable gland located on the
bottom of the housing. Figure 11 shows the polarity of these connections:
Figure 11 – IP65 Version (Connections internal view)
Note: Be sure that the cable gland holds the wires, ensuring the protection level of this model: IP65 − Fully protected against the entry of dust and against water jets, according to NBR-6146 standard.
IP67 MODEL
In the IP67 version, a M8 connector is provided for signal input.
When required, a second M8 connector can be installed to output the signal for
commanding the external power supply. The cables are supplied with the logger.
Note: You should remove the logger cover only when it is necessary to
change the battery. On this occasion, the cover must be put back properly,
ensuring the protection degree of this model: IP67 − Fully protected against
the entry of dust and against immersion in water, according to NBR-6146
standard.
Figure 12 – IP67 Version (External connectors)
The wires have the following connections:
Table 1 – Channels cable
CHANNELS CABLE (RIGHT) | CONNECTION |
---|---|
Blue | Channel 1 – (3 IN1) – positive (+) |
Black | Channel 1 – (4 GND) – negative (-) |
White | Channel 2 – (1 IN2) – positive (+) |
Brown | Channel 2 – (2 GND) – negative (-) |

Figure 14 – NPN and PNP open collector input
Figure 16 – Example of the battery switch powering a transmitter.
INPUT CONNECTIONS – ANALOG CHANNEL
To use channel 2 properly, the internal jumpers J1 and J2 must be positioned
according to the chosen input type, as shown in Table 3.
The setting of these jumpers is for measuring 4-20 mA or 0-20 mA signals.
The following figures show the connections for the possible input types:
Figure 15 – Current and voltage inputs
Table 3 – J1 and J2 positioning
INPUT SIGNAL | J1 POSITION | J2 POSITION |
---|---|---|
4-20 mA / 0-20 mA | A | A |
0-10V | B | B |
0-50 mV | C | C |
EXTERNAL BATTERY SWITCH
The figure below shows an example of using the internal electronic switch
during the actuation of external devices.
In this example, channel 2 is configured for the 4-20 mA signal. The
transmitter that generates this signal is powered by an external battery. This
power supply is commanded by the logger via the Electronic Switch that
“switches on” the power supply seconds before the logger measures channel 2.
This measure allows the external battery to power the logger for a much longer
time.
INSTALLATION RECOMMENDATIONS
Small electrical signal conductors should run through the plant separately
from drive conductors or conductors with high current or voltage values. If
possible, in grounded conduits.
The instrumentation supply must come from a proper instrumentation network.

SPECIAL PRECAUTIONS
Because it is an electronic device, the logger requires some basic precautions:
- When opening the unit to change the battery or attach sensors, you should avoid contact with the circuitry due to the risk of damage from static electricity.
- When the device is opened, avoid liquid and/or dust contact.
- You should pay attention to the battery polarity. The battery should be placed with the positive terminal toward the center of the device.
- Used batteries must not be recharged, disassembled, or incinerated. After use, they must be collected according to local legislation or sent back to the supplier.
- When closing the housing, the cover must be put back on properly, ensuring the degree of protection of this model.
TROUBLESHOOTING
The indicator does not blink:
The indicator blinks intentionally dimply and can be difficult to see it in
high-light locations. Therefore, you need to make sure that it is not actually
blinking.
Check that the battery is correctly installed.
Make sure that the battery is not discharged.
It is not possible to communicate with the logger:
Make sure that there are no obstacles blocking the infrared signal. Make sure
that the cable is properly connected to the computer port. Make sure that the
selected port is working properly.
