Hardware Installation

Slide the device upwards onto the DIN rail. Push it up and towards the rail until it snaps onto the upper rail edge. Before powering the device please read this quick install guide and mind the polarity of the power supply (see picture on page 2).

Connecting to power and initialization

Power Supply

The Barionet 200 needs a DC supply voltage of 9V to 30V, 4W max. Please mind the polarity. When powered up, the Status LED of the CPU will start blinking, indicating that the device is starting up.

BLUE CPU LED: Main CPU

When the device is initialized, the Status LED turns solid, the other LED will turn off (assuming no active IO is connected).

Power over Ethernet (PoE)

The Barionet 200 also offers the possibility to be powered by PoE. Simply connect a PoE supplied network cable into the network port and the device is starting up.

Connecting via Ethernet

Plug an Ethernet cable from the Barionet 200 to an Ethernet network.

The Barionet 200 is configured to be a DHCP Client by default. Use a Network Scanning Program or the Barix Discovery Tool in order to determine the IP Address according to the given MAC Address.

The Ethernet Interface can be configured using the Barix Web Interface. Use your Webbrowser in order to connect to the determined IP Address. The Root Password of the Device can be found on a sticker on the Backside of the Device. Use the "Ethernet" Section in order to configure the Ethernet Interface.


Connecting via Wi-Fi

Please note that the default Wi-Fi Interface is only turned on for the first 5 minutes after powering the device. Once a Wi-Fi is configured, the Wi-Fi Interface stays on.

The Wi-Fi Interface is turned on by default offering an SSID which is called “Barionet_” and the four last digits of its MAC address (for example, Barionet_0024B5). The security key/passphrase “barionet” is used to protect the WLAN.

Connect your PC to this Wi-Fi network. For this network, the Barionet works as a DHCP server and uses the IP Address 192.168.166.1 itself. For your PC, an IP address in the 192.168.166.x range will be assigned.

The Wif-Fi Interface can be configured using the Barix Web Interface. Use your Webbrowser in order to connect to the Device IP Address (192.168.166.1). The Root Password of the Device can be found on a sticker on the Backside of the Device. Use the "Wi-Fi" Section in order to configure the Ethernet Interface.


Leave your Wi-Fi IP address as DHCP or configure a Static IP. Use the "Scan" Button to search for available Wi-Fi Networks. Select one of the available networks and enter the Wi-Fi Access Key in order to connect.

For security reason, we recommend to turn off the WLAN interface if it is not needed in the Application. Use the LuCI Webinterface -> <Network> -> <Wireless> in order to turn the Interface off.

Resetting the Network Configuration

If you have entered a wrong Network configuration (Wi-Fi or Ethernet IP etc.), the Network configuration can be reset using the Factory Defaults Button. Press the button for 3-5 Seconds and the Network Configuration is reset to factory defaults (Wi-Fi reset, Ethernet back on DHCP).

Setting Ethernet to Factory Testing IP

The Ethernet Interface can be set to the Factory Testing IP address 192.168.166.1 using the Factory Default Switch. Press the Factory Default Switch for more then 20s (Blue LED will turn off) and the Ethernet IP Address will be set to static IP 192.168.166.1. Please note that this Setting is for configuration only, the Ethernet Configuration will be set back after a Reset if not otherwise configured.

Changing Settings via Advanced Luci Web Interface

Opening the Advanced LuCi Interface

For advanced users the LuCI web interface can be accessed via the Barix Webinterface using the Advanced Section -> "LUCI config interface".

Login Data are the same as for the Barix Webinterface, the password for the Root user can be found on the sticker on the backside of the device.

Changing Network Settings

In the LuCI web interface -> <Network> you will find all relevant settings, so you can set other IP addresses, enable/disable DHCP for each network port (Wi-Fi or Ethernet), and also enable the Wi-Fi interface.

Make sure you don’t lock yourself out if you change the settings !

Control IOs

In the LuCI web interface -> <Barionet> you will find a Control Interface to control and monitor the GPIOs of the Barionet.

Simply click on the Control Buttons to change the state of Relays and IOs or see the Status of Digital Inputs.

Connecting via SSH

Use ssh or a similar client (for example, PuTTY, port 22, SSH option) and establish a connection as user “root” to the IP address of the Barionet (given DHCP Address if connecting via Ethernet or 192.168.166.1 if connected via Wi-Fi). The SSH root password is the same as used for the Webinterface which can be found on the sticker on the backside of the device.

Installing OpenWRT Packages

OpenWRT Packages can be installed by the standard OpenWRT/Lede Package installer by using “opkg” command


opkg list opkg list lists all the available packages

opkg list-installed lists the installed packages

opkg update updates the installed packages

opkg install <file> installes a specific package

Please note all custom installed packages will be deleted if a factory defaults or firmware update is applied.


Updating the Barionet Application Packages

The Barionet Software is represented by different Packages in the Barionet Feed. In order to update the device to the newest Software without loosing any data, the Barionet Packages will need to be updated.

This Update can simply be done by the Webinterface.

IO Access from Scripts or programs

The IO ports are accessible through the standard OpenWrt IO device files.

The Device Files can be found in the folder /dev/gpio.

Digital Input

Digital Inputs: bio201

Use the following shell command in order to read the digital input value:
cat bio201/value reads Input 1

Green LED

Green LED: green_led

Use the following shell command in order to control the green led:
echo 1 > bio1/value set Relay 1
echo 0 > bio1/value reset Relay 1

Mounting a USB Stick

A USB Stick with FAT32 File System can be plugged into any of the USB ports. In order to mount a USB stick to the OpenWRT File System the following command is used:

mount -t vfat /dev/sda1 /mnt/usb mounts the sda1 (first USB stick)


Note that “sda1” is eventually replaced by another interface. Use dmesg in order to determine the right interface.

Note that the /mnt/usb directory needs to be created before mounting.

Use of Modbus

The Barionet 200 is supporting Modbus TCP Protocol in order to be controlled.

Modbus Interface: TCP Port 502

All IOs as well as a lot of more functions are accessible via Modbus IO Registers according to Appendix 1) IO Mapping.

Programming the Barionet in Lua

All the Devices in the Barionet Product Familiy can easy be programmed in Lua programming language. The important Lua packages in order to user IOs and Interfaces are pre-installed in the default Barionet Images.

Please use www.lua.org in order to get familiar with Lua and how it is programmed.

The Lua program will be loaded to the Barionet Device using SSH (see above). The program should be stored in /mnt/data/default.lua in order to be executed automatically after startup.

Persistent User Partition

The user partition (/mnt/data/) is the flash space which is persistent to firmware updates and factory defaults. All custom developments will need to be done in the User Partition in order to be on the device after a firmware update or a factory defaults.
