DTXr documentation¶

Installation¶

• System Requirements
  DTXr can run on any machine that can run Java 11 and has sufficient with RAM and disk capacity.

Requirement	System RAM	System DISK	Example
Minimal	512Mbyte	512Mbyte	Raspberry 1, Raspberry Zero
Better	512Mbyte	512Mbyte	Rasberry Zero 2
Avarage	1GByte	1Gbyte	Raspberry 2-4
Top	2GByte	8Gbyte	Raspberry 4, Raspberry CM4, Server, PC

• Network Requirements
  DTXr can run stand alone without any active network connection. In that case the management pages is accessible via localhost interface. But for DTXr to be a fully functional BACnet/IP device it must be connected to an IP network that offers IP address via DHCP and where broadcast traffic is allowed.

• Download DTXr software packages
  Currently only customers to DAVITOR can download DTXr. Contact info@davitor.com for purchase information.

• Install on Linux
  • There is special install scripts, please follow these steps:
    1. Download latest DTXr base image and copy to a SD-card that has 16Gbyte capacity or more

Or install a new image and install java

sudo apt install default-jdk 

1. Insert the SD card, attach keyboard and screen via cable and start the device
2. When you get prompt login as admin/davitor
3. Download the installation script from davitor repository (note dtx.sh has an update since Jan 17th, 2024 see new parameter installfolder below)
   

   wget --user=**** --password=**** https://artifacts.davitor.com/repository/dtx-raw/scripts/dtx.sh

   
   There is also a utillity script that can set the host name and MAC adress. Note, optional and only applicable on LION product appliances.
   

   wget --user=**** --password=****  https://artifacts.davitor.com/repository/dtx-raw/scripts/system.sh

   
   Make the scripts exec
   

   sudo chmod 770 *.sh

4. Run installation as below where you first alter:
• Required version (-v x.y.z)
• The the install folder (-f myfolder) Note: Still relative to /usr/local so (-f myfolder) results in /usr/local/myfolder/dtx...
• Partner user name (-u **)
• Partner password (-p **)
• Application password for the HTTP interface login on port 9090 (-app-password xxxxxxx)
• BACnet Decvice Id (bac-device-id=nnnnn)
• BACnet password which you will use to control the BACnet device DCC (bacnet-password=xxxxxx)
• BACnet Device Name (bac-device-name=yyyy)
• DAVITOR Reference Key (drk=xxxx) is used to mange and maintain this device from the DAVITOR PLM (Product Lifecycle Management) service. (drk=xxxx) The sequence of drk:s is in PLM instance database.
• Hardware Platform Type (platform=xx) is used to control and switch on/off special features that is hardware dependent.
  For LION products use:
  

  sudo ./dtx.sh -v 3.1.20 -f myfolder -u **** -p **** -s "bac-device-id=nnnnn bac-device-name=yyyy app-password=xxxxxx bac-password=xxxxxx lion-enabled=true drk=xxxx platform=XX"

  
  For other installations like PC, Servers etc. use:
  

  sudo ./dtx.sh -v 3.1.20 -f myfolder -u **** -p **** -s "bac-device-id=nnnnn bac-device-name=yyyy app-password=xxxxxx bac-password=xxxxxx drk=xxxx platform=XX"

1. Utillity script to set MAC and host name
   

   sudo ./system.sh -mac 70:B3:D5:16:E8:99 -hn DTX-L1-8R8DI

• Upgrade on linux
  If you already have DTX installed and should upgrade to a new version (Don't forget to set correct installfolder with -f)
  

  sudo ./dtx.sh -v 3.1.19 -f myfolder -u **** -p ****

• Manage the DTX service (Note, since 17th Jan, 2024 of dtx.sh the names of the services are appended with the instsall folder in order to install multiple instances of DTX in same machine.)
  Stop

  sudo systemctl stop dtx_{installfolder}

  
  Start

  sudo systemctl start dtx_{installfolder}

  
  Check status

  systemctl status dtx_{installfolder}

  
  Disable service, wont start at reboot

  sudo systemctl disable dtx_{installfolder}

  
  Enable service, will start automatically at reboot

  sudo systemctl enable dtx_{installfolder}
