Barix Barionet 1000

The Barionet 1000 is a 802.11ac+bgn multi-purpose wireless, universal, programmable I/O device server built around the MediaTek MT7620A SoC with OpenWrt OS. It has 1 Ethernet port , a 802.11n 2T/2R 2.4 GHz 300Mbps wireless interface and two USB 2.0 ports. The device controls two relay outputs (max: 30VDC 5A) and four open collector (digital) outputs (4x24VDC, 0.3A ). It also has eight contact closure Inputs ( 0-15VDC) and four are 12 Bit analogue Inputs (0-15VDC). A (DSub-9 male) RS-232 Serial Port provides serial interface. The system is equipped with 11 LED status indicators and one molex connector to enable 1-Wire interface.


Runs on OEM OpenWrt version, but not officially supported by OpenWrt (no images available at

The above image displays the several out of the box available interfaces. The Barionet 1000 is commonly powered by a good quality transformer capable of delivering a stable voltage of 12 VDC at 1.5A. As shown in the image above, the power is supplied via the J1 connector. Before plugging in the adapter be aware of the polarity of the wires to avoid damaging the unit.

Before powering Barionet 1000 please make sure to comply with the following specifications for cable type:

  • I/O, Power Connectors: 28 AWG minimum to 14 AWG maximum wire size
  • Relay output: 26 AWG minimum to 12AWG maximum wire size

It is recommended to use shielded cable with earth connected to the G pin on Barionet 1000.

After properly powering the Barionet 1000 the status LEDs (PWR and IN1 to IN8) will turn on and then the PWR LED will start flashing to indicate that the equipment is booting and it is not yet ready. While the PWR LED blinks with a period of 0.5 seconds, then the unit is still booting. The boot is successfully finished when the PWR LED stops blinking.

The Barionet 1000 needs a DC supply voltage of 9V to 30V, 4Wmax. Please mind the polarity. When powered up, all LEDs will turn on while the power (PWR) LED will blink (blue). When the device is initialized, all LEDs besides the power led (blue) will turn off (assuming no active IO is connected).

Plug the ethernet cable from your computer directly to the Barionet 1000. Next, configure your computer to a static IP on the range 192.168.66.X (for example, .100) and subnet mask to With the Barionet 1000 default configuration its LAN IP address is set to Default username and password: root/(blank) The root user has NO password set, so make sure you set one ! BARIONET 1000 MAIN PAGE

The device works in AP mode by default and creates a Wi-Fi network with a name consisting of “Barionet_” and the four last digits of its MAC address (for example, Barionet_0A15). The network security key/passphrase is “barionet”.

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

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 ( if connecting via Ethernet and if connecting via Wifi) The root user has NO password set, so make sure you set one!

To use the LuCI web interface please access the Barionet via browser by its IP address ( or

In the LuCI web interface you will find all relevant settings, so you can set other IP addresses, enable/disable DHCP for each network port (Wifi or Ethernet), and also disable the wifi interface. Make sure you don’t lock yourself out if you change the settings!

In the LuCI interface go to System  Mount Points menu. Scroll down and select “Add” on Mount Points view. Select the UUID of the external flash drive inserted into the Barionet 1000 USB port. Select option -- custom -- under Mount Point drop down menu and provide a name (e.g. /mnt/usbflash). To validate click on Save & Apply and wait a few seconds. The new mounted unit should now be visible when going to System  Mount Points

The IO ports are accessible through the standard OpenWrt IO device files. Some testing and sample scripts are in the /root directory, which can be used to quickly read inputs or set outputs. Please refer to the IO Map (you can find it in the documentation and also in the device’s /root directory, file “iomap.rtf”)

On the LuCI web interface go to the System  Backup/Flash Firmware Under Backup/Restore select Reset to defaults: Perform reset. At this point, the device will reboot and apply default settings.
