3ENCLOSURE AND USER CONTROLS
3.1 START AND STOP OPERATION
The Avisaro 4.0 starts with operation right after power on if an USB stick is inserted. Also, after re-
inserting a USB stick, the operation starts automatically.
3.2 LED BLINK-CODES
There is one multicolor LED to signal states of the Avisaro device.
Code
What is means
Action
Green & blue fading
All is fine
Idle state, no data arriving
None
Green flashing
Data are coming in
(RS232, CAN interface)1)
None
Yello constant
All is fine, USB stick is
checked after mounting
None
Red flashing
No USB stick
or button was pushed
Insert USB stick
Or press button again
1) On analog loggers (e.g. 4…20mA) and similar interfaces, data are read continuously, thus no green
flashing is shown
3.3 REAL-TIME CLOCK
A battery buffered internal real time clock is available for time stamping data, start and stop network
upload and others controls. The battery is a rechargeable “memo-buf” cell - specifically designed for RTC
operations. During regular operation, the battery is recharged over a 48h period. During non-operating
times (= supply power off) , the date and time settings are maintained.
If the Avisaro device is networked, a network time server (SNTP) can be used to set time and date
automatically.
If a Avisaro GPS receiver is connected, the RTC can be set using satelite time.
It is possible to define time zones settings.

4USB STORAGE STICK
4.1 FILESYSTEM AND STORAGE SIZE
Commercially available USB 2.0 / 3.0 memory sticks can be used. It is recommended to exclude branded
products - no "promotional items" with your own logo imprint.
There are no speed requirements. Memory sticks that are advertised as particularly fast offer no (!)
advantage in the Avisaro data logger. Typically these optimizations are designed for cameras etc..
Memory sizes from 4 to 256 GByte are supported. As file system FAT or FAT32 (preferred) is used. NTSF
or others are not supported.
Memory sticks are typically not in the scope of delivery - each application typically has different
requirements.
4.2 CHOOSING THE RIGHT MEMORY STICK
For industrial use, special parameters may have to be observed.
The temperature range should be considered. There are "industrial grade" memory sticks available -
often designed as "SLC" version - which are also suitable for harsh environments.
The mechanical dimension should also be considered. It is disadvantageous if the stick protrudes openly
from the housing and could be knocked off. In this case short sticks are recommended. If the logger is
installed protected, then a longer stick is easier to use.
The appropriate memory size also depends on the intended use. Due to the technology, memory sticks
with an extremely high capacity are typically less robust than smaller memory sizes. The loggers have a
"ring memory" that can be optionally activated. If the memory stick becomes full (approx. less than
100MB free memory) the oldest files are deleted - this is a useful setting for some applications.

5INTERFACE DESCRIPTION AND PIN LAYOUT
5.1 MICRO-USB CLIENT
The Micro-USB client interface is used for configuration only.
Most Avisaro devices are powered through the Mico-USB client port, however only for configuration. A
stable regular operation is not guaranteed. Use the regular power supply for normal operation.
A “Micro USB” cable is used. As those cable are widely available, this cable is not part of scope of
delivery to avoid electronic waste.
5.2 RS232 INTERFACE
This is an industry standard RS232 connection.
5.2.1 Default RS232 settings
Those are the default settings:
Baudrate
9600
No of bits
8
Parity bits
none
Stop bits
1
Flow control
none
5.2.2 Signal levels
Max Input voltage range on signal pins: -24 to 24 V
Output level provided: -5V to 5V
5.2.3 D-Sub Connector
Industry standard SubD-9 connector (male)

Power
Supply voltage does not carry an output voltage –thus if the device is powered via barrel connector, Pin
9 does not show the input voltage (internal diode). This is for security reason. If needed, Avisaro can
modify the device such that this pin can be used to power other devices.

6CONFIGURATION:‘PC COMPANION SOFTWARE’
6.1 HOW TO CONFIGURE AVISARO “SERIES 4.0” PRODUCTS
The basic principle of how to configure the Avisaro “Series 4.0” products is:
1) Download and install the “Avisaro PC Companion Software”.
2) Connect the Avisaro device via USB cable.
3) Choose the correct COM port and click on “connect”.
4) The software presents all the settings you can make and guides you to avoid conflicting
configurations.
5) Click on “save configuration” to store changes in the Avisaro device.
6) Reboot the Avisaro Device so that the new configuration takes effect.
Details are described further down in this document.
6.2 CONCEPT OF OPERATION
The Avisaro 4.0 is divided into sections:
Data are received through an “Interface” and then forwarded to the “Data Processing” section. All
formatting happens here and then data is forwarded to the “Data Endpoint”.
6.3 DETAILED DOCUMENTATION
This current document shows only selected parts of the full “Avisaro PC Companion Software”user
manual. The motivation is to keep this document as compact as possible.
