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
  • For Raspberry with Raspberry OS/Rasbian 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
    2. Insert the SD card, attach keyboard and screen via cable and start the device
    3. When you get prompt login as admin/davitor
    4. Download install scripts with password for davitor sight

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

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

    5. Run installation as

       sudo ./dtx.sh -v 2.25 -u admin -p **** -s "bac-device-id=83336 bac-device-name=DTX-AMADA app-password=xxxxxx lion-enabled=true" 
       

       
       The line above is an example where chosen parameters where set at installation and where xxxxxx is the new password for the new device to use.

1. Set MAC by system.sh script
2. Example:
   

   sudo ./system.sh -mac 70:B3:D5:E6:00:10 -hn WASH

This will excecute nesesary commands as well as change the file
/lib/systemd/system/setmac.service

**[Unit]
Description=DSet the MAC address for the ENC28J60 enet adapter at eth0
Wants=network-pre.target
Before=network-pre.target
BindsTo=sys-subsystem-net-devices-eth0.device
After=sys-subsystem-net-devices-eth0.device

[Service]
Type=oneshot
ExecStart=/sbin/ip link set dev eth0 down
ExecStart=/sbin/ip link set dev eth0 address 00:00:00:00:00:00
ExecStart=/sbin/ip link set dev eth0 up

[Install]
WantedBy=multi-user.target

Replace the "00:00:00:00:00:00", by a MAC-address of your choice, but keep the first pair of zero's. Then do this:
$ sudo chmod 644 /lib/systemd/system/setmac.service
$ sudo systemctl daemon-reload
$ sudo systemctl enable setmac.service**

System files
*settings.json
/usr/local/davitor/dtx/settings.json
The file contains most of the important settings that is used by the DTX environment and most of it can be changed from the settingspage.
If the file is changed manually, than please stop dtx envronment by:
use of *systemctl *

sudo systemctl --help

systemctl [OPTIONS...] {COMMAND} ...

Example:
Stop
sudo systemctl stop dtx

Run
sudo systemctl start dtx

Check
systemctl status dtx.service

    When you log in you will start att /home/admin
    There is another user "pi" as well with a secret password.
  • Operator username - Username for the typical user of any HMI developed on this device. Typically a machine operator. [Optional]
