h3. 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:

### 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

<pre>sudo apt install default-jdk </pre>

### Insert the SD card, attach keyboard and screen via cable and start the device

### When you get prompt login as **admin/davitor**

### Download the installation script from davitor repository 

*(note dtx.sh has an update since Jan 17th, 2024 see new parameter 'installfolder' below)*

*(note dtx.sh has an update since Nov 6th, 2025 see new parameter 'type' below)*

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

Make the scripts exec

<pre>sudo chmod 770 *.sh</pre>

### Run installation as below where you first alter:

*** Required type (-t type) where type can be "scriptengine" for small platforms like RpiZ with 32-bit OS or "polyglot" for any 64-bits OS like servers or PC.

*** 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:

<pre>sudo ./dtx.sh -t scriptengine|polyglot -v 3.1.23 -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"</pre>

For other installations like PC, Servers etc. use:

<pre>sudo ./dtx.sh -t scriptengine|polyglot -v 3.1.23 -f myfolder -u **** -p **** -s "bac-device-id=nnnnn bac-device-name=yyyy app-password=xxxxxx bac-password=xxxxxx drk=xxxx platform=XX"</pre>

### Utillity script to set MAC and host name

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

* 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)*

<pre>sudo ./dtx.sh -t scriptengine|polyglot -v 3.1.23 -f myfolder -u **** -p ****</pre>

* 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<pre>sudo systemctl stop dtx_{myfolder}</pre> 

Start<pre>sudo systemctl start dtx_{myfolder}</pre>

Check status<pre>systemctl status dtx_{myfolder}</pre>

Disable service, wont start at reboot<pre>sudo systemctl disable dtx_{myfolder}</pre>

Enable service, will start automatically at reboot<pre>sudo systemctl enable dtx_{myfolder}</pre>
