DMR configuration (channels, groups, subscribers)

Channels are defined using ZZZ.NNN, where Z stands for the zone and N for the channel number.
Example: 1.2 → Zone 1, Channel 2 (entered without a leading zero).

DMR devices always require a target for communication. This can either be an individual subscriber or a group:

Individual subscribers are defined by a number or with U.
Example: 123 or U123 → subscriber with call number 123

Groups are defined with G.
Example: G4 → Group 4

PTT always transmits to the selected phonebook entry (subscriber or group). LARDIS can be configured so that it automatically switches to the corresponding subscriber upon incoming calls.

Shutting down the system via external switch contact

ℹ️ Available from version 5.5.1 (Gen1 and Gen2)

 

Using a volt-free external switch contact (e.g. from an existing building or vehicle-side PLC), it is possible to automatically shut down the LARDIS Touch Wxx PC. The PC must be logged into the system for this function.

To do this, connect the switch contact between DSR (Pin 6) and DTR (Pin 4) on one of the serial RS-232 interfaces available on the LARDIS Touch Wxx PC (D-Sub9 / RJ45).

The serial interface used must be configured in the DeskConfig.ini file. This file is located at D:\Radio Desk Software or can be accessed via the network share \IP-ADRESS\Radio Desk Software, where [x] is the number of the respective LARDIS Touch PC. In this file, a line with the content shutdown@COM[x] must be added, where [x] is the number of the serial port used. If the entry already exists and is commented out with a hash symbol (#), the hash must be removed to activate it.

When the switch contact is closed, the system will shut down completely and safely. After the system has completely powered down (the status LED on the device changes from green to amber), the PLC can also switch off the power supply to the LARDIS Touch Wxx PC, and the switch contact used for shutdown can be opened again. There should be a sufficiently long delay (run-on time) between closing the switch contact to initiate shutdown and switching off the power supply; otherwise, there is a risk of data loss and potential damage to individual file systems if the power supply is switched off “hard”.

To switch the device back on later, simply restore the power supply via the PLC.

ℹ️ Available from version 6.x (Gen1 and Gen2)

 

Handling is as described above, with the following addition:
From this version onwards, it is possible to shut down the Touch PC without prior login. Only the Desk software needs to be running (default: autostart).

 

⚠️	Do not use or configure COM5 if it is available!

 

My microphone on my own hardware is not being detected – what can I do?

The following conditions can cause this problem on non-LARDIS hardware:

• Is an antivirus program installed? (Kaspersky and Avast actively block access to the microphone)
• Is the microphone blocked in Windows privacy settings?
• Was the microphone connected only after LARDIS was started?

Error message: "No license available"

The system message "No license available" may appear when logging into the LARDIS-DESK workstation. There are two possible causes for this message:

1. An additional workstation attempts to log in, although the maximum allowed number of active workstations has already been reached. In this case, the error message is correct.
2. You are trying to log in again after a system crash, an improper system shutdown, or a shutdown caused by battery failure on mobile devices. In this case, the error message is misleading.
   
   Cause: It is possible that the running LARDIS-DESK workstation was not properly closed due to an improper system shutdown. In this case, the LARDIS-BOX does not immediately detect that the connection to the computer was unexpectedly interrupted. If you then try to reconnect to the LARDIS-BOX via the LARDIS-DESK workstation, the LARDIS-BOX rejects your login attempt, mistakenly assuming multiple simultaneous uses of your license. Please wait a short moment and then try to reconnect or log in again.

What is the difference between LARDIS:ONE and LARDIS:PILOT?

How do I set up the status system (Tetra BOS) correctly?

This FAQ explains the correct configuration of the status system, in addition to the documentation (LARDIS:ONE or LARDIS Manager). Some of the information given depends on the local conditions and must be adapted accordingly.

Status codes: These are uniform decimal values that are transmitted via SDS to the control station or secondary control station, for example. Unlike in analog FMS, these values have five digits.

Status 0: 32770
Status 1: 32771
Status 2: 32772
Status 3: 32773
Status 4: 32774
Status 5: 32775
Status 6: 32776
Status 7: 32777
Status 8: 32778
Status 9: 32779

For more general information on the radio messaging system, visit: https://de.wikipedia.org/wiki/Funkmeldesystem

Status confirmation: Control stations usually send a status confirmation back to the subscriber in response to a received status message. This SDS (PID 204 / 220) contains a defined text, which often differs nationwide. The confirmation text you use must be entered accordingly for each status and must be exactly the same in wording. It is also possible to evaluate only a partial content of the SDS (tick at partial content). However, this part should not be chosen too short or general, otherwise it could lead to false evaluations!

How to find out and configure the confirmation texts you will learn here: Configure status confirmation

It is possible to use the received TETRA ACK as confirmation. However, this does not indicate whether the status was actually received correctly in the control center.

If your area of operation extends over several control stations and requires the configuration of different confirmation texts, this must be configured via the "Multiple acks" checkbox. If this check mark is set, a button is displayed which allows different confirmations. These are to be separated line by line.

 

The instructions sent by the control station (usually Flash-SDS / PID 137) can be defined specifically and configured with further actions.

The contents of the control center instructions often differ supra-regionally and can therefore only be requested locally or determined as an exported event (see status confirmation).

How does the LARDIS Navigation work?

This article describes supplementary information about navigation. The basic use of navigation is described in the LARDIS-ONE 2.x User Manual.pdf.

With the arrival of the new LARDIS:ONE (mini, DS) hardware in 2022, an own navigation application was developed, which works on the basis of an external API and map provider. In direct comparison to the previous LARDIS:ONE 7 hardware (Garmin), this can be better integrated into the LARDIS:ONE application.

The map sets are based on data from OpenStreetMap. This way the end user also has the possibility to make corrections and adjustments himself. Further information can be found here. As a rule, an update of the map sets is offered on a quarterly basis.

Traffic data: LARDIS:ONE (mini) can retrieve this data via WLAN and mobile data (possibly subject to a charge) and display it visually (using colored lines on the respective road) on the map. The navigation does not use this information for route calculation.

What is a secondary control center?

With LARDIS and LARDIS:ONE, it is possible to send a status message to a so-called "secondary control center" (fixed number as destination) in addition to a status message to the control center. This makes it possible to send a message (status, text, position) in parallel to e.g. the own operations center or an command vehicle.

A status is only sent to the secondary control center when the regular status dispatch to the control center has been completely processed. This also concerns, among other things, a correct status confirmation or a Tetra-ACK.

Further information can be found in the documentation for the LARDIS-ONE 2.x or for the LARDIS Manager.

How do I create a logtrace in LARDIS:ONE?

ℹ️ Available from version 2.x

 

To create a logtrace on LARDIS:ONE devices, you have two options. The first option is executed directly via the LARDIS:ONE interface. To do this, long press on the LARDIS logo on the left edge of the screen.

The window that opens now shows you the output of the debugger. Press the red Record button for a background recording and then reproduce the error. You can return to the familiar LARDIS interface by briefly tapping the LARDIS logo again.

After creating the log, connect the LARDIS:ONE to a PC via USB and start the LARDIS setup there. Use the Actions menu to call up the item "View log files...". You can now save the log data displayed there and send it to support.

 

Record log trace directly via LARDIS setup

Connect the LARDIS:ONE to your PC via USB and start the configuration software "LARDIS Setup". Now select the "Debugger..." item in the Actions menu. Reproduce the error and save the log data. You can send these to the support.

How can I update the Garmin navigation device?

Is it possible to avoid level crossings or certain roads with the help of LARDIS:ONE 7?

Yes, via the item "Settings - Navigation - Route Preferences - Own Avoidances" roads and areas can generally be excluded from the routing.

It is also possible to transfer road blocks to the LARDIS:ONE via SDS:

To activate the road block function, please refer to the information in chap 4.5.1. of the LARDIS:ONE configuration manual.

The following describes the syntax of the roadblock commands as it can be processed in received text SDS messages. There are three commands available:

##AVD##[ID][Name][Coordinates]

- Function: Setting a roadblock
- ID = three- or four-digit number as unique identification code of the roadblock
- Name = unique name of the roadblock (in the device settings, a maximum of the first 24 characters are displayed)
- Coordinates = coordinates in any of the supported data formats, which are also used for destination guidance (the data format can also be placed at the beginning of the message, before the ##AVD## identifier, if the data format supports this positioning at the beginning of the message). Please always select the center of the closed road as the point of the coordinates.
- Example: ##AVD##020Waldstrasse[coordinates]

##AVD##[ID]DELETE

- Function: Delete a roadblock
- ID = three or four digit number (unique identification code of the roadblock).
- Example: ##AVD##020DELETE

##AVD##[ID]DELALL

- Function: delete all roadblocks
- ID = any three- or four-digit number
- Example: ##AVD##000DELALL

Disabling the warning message on the LARDIS:ONE 7 (Garmin Fleet 7xx)
