First steps
Software
Unipi Patron unit is based on OS Linux (Debian). Unipi provides several OS images containing different pre-installed
applications. The default image is
Mervis OS
containing Mervis RT and all necessary files for the unit to operate. The
image can be reflashed (see below) with a custom image, or with one of the pre-assembled images available on the
Knowledge Base.
Mervis OS
: SSH access is disabled by default. It can be activated using service mode or via the Mervis IDE. The default
login info for SSH access is username: „unipi“, password: „unipi.technology“.
We strongly recommend changing the login
credentials immediately after SSH activation.

Unipi Patron unit startup
1.
Connect the unit to a local network using a network cable (RJ45).
2.
Connect a power supply compliant with the unit’s product label. Wait for at least 20 seconds until the unit fully
boots up.
3.
Upon startup, the unit will automatically attempt to obtain an IP address from the DHCP server. If the attempt is
unsuccessful, the unit will use a random IP address from a range of 169.254.0.0/16. A default static IP address
can be assigned in the service mode.
4.
An mDNS record is simultaneously published into the network, making the unit available under a unique name.
E.g:Patron S107 with serial number 123, would be accessible at „http://s107-sn123.local“. The serial number can
be found on the unit’s product label.
5.
Mervis OS only: the default web page will be displayed upon entering the URL into a web browser. This page
can be edited in Mervis IDE.
Service mode
Service mode is a web tool for IP configuration, (de)activation of Mervis and SSH services, reflashing of OS images,
creation of OS backup to USB flash disk and other useful functions. To activate the service mode, follow these steps:
1.
Remove any connected USB flash drives and connect the unit to a local network or directly to your PC, using a
network cable.
2.
Press
and hold
the „SERVICE“ button on the unit’s top side.
3.
Connect a power supply. All outputs are set to their default configuration, all outputs are disabled by default.
4.
Patron will boot into a service mode indicated by slow blinking of all LEDs in both upper and lower rows (only
Section 1 on M and L units). You can now release the button.
5.
The unit will set its own IP address to 192.168.200.200 while simultaneously attempting to obtain an IP address
from the DHCP server. The unit will be then available at both IP addresses.
6.
To access the service web interface, use a web browser and enter the IP address http://<ip-address>
Reflashing the operating system
The operating system can be reflashed via the service web interface or by using a USB flash disk.
Caution: Reflashing
will delete all data stored in the unit’s onboard memory storage.
Download and extract the selected ZIP archive with Patron OS image from Knowledge Base (
to your PC or use files from USB backup.
Reflashing the OS using service web interface
1.
Switch the unit into the service mode (see above).
2.
Drag only the
archive.swu
file from the extracted archive and drop it into the Software Update dialogue
in the service web interface.
3.
Wait until the process is finished – reflash progress can be seen in the Software Update dialogue.
4.
The unit will automatically reboot upon successful OS image reflashing procedure.
Reflashing the OS using USB flash disk
1.
Prepare an USB flash disk with at least 2GB of free memory (FAT32 format).
2.
Copy all extracted files from OS image to the USB disk or use the USB flash disk with backup files.
3.
Insert the USB flash disk into one of unit’s USB port.
4.
Press and hold the „SERVICE“ button on the unit’s top side.
5.
Connect power supply.
6.
Patron will start reflashing the OS, the process is indicated by rapid blinking of all LEDs in both the upper
and lower rows (only in Section 1 on M and L units). You may now release “SERVICE” the button.
7.
LEDs will stop blinking once the reflash is completed. The unit then automatically reboots.
Caution: Some USB flash disks may not be compatible. If your flash disk does not work, try another one or reflash
the OS using service web interface.
