What’s new in the C-Bus Toolkit 1.16.0?

What’s new in the C-Bus Toolkit 1.16.0?
eDLT Firmware v1.6.0
The eDLT Firmware Updater has been updated to include firmware version 1.6.0. This incorporates support for eDLT units with the version 3 hardware.
When upgrading firmware on a unit with version 3 hardware, the updater must perform additional steps to complete the upgrade and so the upgrade process may take longer than it does for units with version 1 or 2 hardware.
A new option called Force font data installation has been added to the eDLT Firmware Updater. When selected, it will force the updater to always update the font data on the unit, even if it is already the same version. When unselected, the updater will skip the font data part of the upgrade if it is already known to be the same version as the new firmware being installed. By default, this option is not selected.

C-Bus – DALI-2 Gateway (5502CDGP230)
This release adds support for newer firmware revisions of the C-Bus – DALI-2 Gateway unit (5502CDGP230) when scanning networks.

SpaceLogic C-Bus Controllers
This release adds support for SpaceLogic C-Bus Network Automation Controller (5500NAC2) and SpaceLogic C-Bus Application Controller (5500AC2) units.

C-Gate 2.11.8

How do I access the Configurator and the Visualization webpage?

When accessing the embedded web server of the C-Bus Automation Controller (5500NAC/5500SHAC), the start page is displayed. From the start page, access the configurator and the following user modules:
  • PC/Tablet Visualization
  • Smartphone Visualization
  • Scheduler
  • Trends.
As administrator, configure the controller via the configurator and control user access to these four modules.

If the controller is set to directly access the Visualization bypass the start page, then the Configurator can be accessed using this URL.


How many Administrator User Accounts can the C-Bus Automation Controller have?

The C-Bus Network Automation Controller (5500NAC) and the Wiser for C-Bus Automation Controller (5500SHAC), both Controllers can only have one administrator access.

Username: admin
Password: admin (by default, it can be changed)

Change the default password on the System page.
Path: Configurator → Utility tab → System button → System tab → Admin Access


How to set a timeout page on 5500NAC/SHAC Using javascript?

In NAC/SHAC > Scripting > edit custom JavaScripting

Copy and paste the code below

Modify adjust the timer value to your need (i.e 20000 = 20 sec)

Set the Current plantID to the page that you want it to time out too. For example high light in yellow showed on image below.

$(function() {


 // Back to Start after x seconds (in miliseconds)

 var SE_Timeout = 20000; // adjust this timer value if needed (20 seconds in miliseconds)

 var SE_Startpage = currentPlanId; // First page that is loaded

 var eventlist = 'vclick vmousedown vmouseout touchend';


 // Timer function no usage detected

 function No_Usage_Detected(callback, timeout, _this) {

  var timer;

  return function(e) {

    var _that = this;

    if (timer)


    timer = setTimeout(function() { 

      callback.call(_this || _that, e);

    }, timeout);






 // Back to start function when timer elapsed

  var SE_Goto_Startpage = No_Usage_Detected(function(e) {

  if ( currentPlanId != SE_Startpage ) {



 }, SE_Timeout);


 // Add event listener to document to detect user input


 .on(eventlist, function() {




 // Add event listener to all iframes to detect user input inside iframes

 $('iframe').load(function() {

  var iframe = $('iframe').contents().find('html');

  iframe.on(eventlist, function(event) {









Are the backup files tar,gz interchangeable between the 5500NAC and the 5500SHAC?

A backup made on the NAC can be transferred to a SHAC and vise versa.

Considerations will need to be made in the circumstances where a SHAC limitation might be exceeded by a NAC project though (BACnet object limits, Modbus device limits, user account limits etc).

There are also options within the NAC/SHAC as well if the need to import or export sections of a project such as visualisations and scripts.
