This chapter covers the configuration of the MX33 - Module.

First Steps

To open and close the module menu, left-click on the appropriate button in the main menu bar:


The Modules window appears - right-click inside the empty module view to create a new module:

The Mx33 - Module

Mx33 is a module with which a dynamic tie-line assignment (see Tie-Lines) with respect to a defined switch is made possible. This module is mainly used with intercom system applications.


Module Mx33

A switch, monitored by the module, is defined as trigger for all following switches. The signals triggering these switches are set-up in a separate view (see Views). This view is then dragged and dropped from the views list into the field Monitored.



Enter a name for the module in the field after Module Name. The targets (dynamic tie-lines, see Tie-Lines) whose outputs are, for example, forwarded to an intercom system, are placed in a separate view. Place the view with these signal paths in the field Resources. In addition, a unique prefix, for example Mx33, must be defined that will be needed later during the definition of meta gadgets (see Meta Gadgets). Moreover, a virtual loop-through device is needed to tap the input (target) of the triggering source.


The signals used in the two views as well as the loop-through device must be deposited in the meta gadgets and defined there as follow:

  • Signals from the view Monitored – definition in meta gadgets:
  • Sources: virtual output (source) of the triggering source, physical input (target) of the triggering source
  • Targets: Source (output) connected to the monitoring target.
  • Signals from the view Resources – definition in meta gadgets:
  • Targets: includes the target that is forwarded to the intercom system for recording
  • Source that is lead back into the control system from the intercom system with signal and voice (mix).
  • The virtual loop-through device includes the physical target linked to it.

The Alias of the signals in the meta gadgets must be defined as follows (see Objects in Meta Gadget Containers): {Prefix from Module Definition}Q{0-2}{"Source" or "Target"}, for example: Mx-Q1-Source.

Additional Information for Mx33 and Mx34 - Module

In addition to the settings explained under Mx33 and Mx34, the following must be considered configured for the two modules Mx33 and Mx34:

  • As usual, pseudo devices (see Pseudo Devices) have to be set for the RX and TX connections:


  • Triggering targets must (for prioritization) be defined as 4-Wire in the signal path attributes (see Signal Path Attributes).


  • For 4-Wire switches, the sources of the return path can be set to blind as well. To do so, use a (virtual) target that is defined as blind-source (see Signal Path Attributes).
  • The first triggering starts the preset connection; the second triggering merely makes the function Talk available.
