In the pane Other Options of the dialog, you can define the following features for the Module currently selected in the Console:
Access group: Select here to which Access Group the module belongs. All modules in an Access Group work together for certain functions, e.g. for setting parameters of a Fader Channel from the central Console. There are four Access Groups available.
Module ID: This is the unique identification number of the Module in the RM4200D Device.
Invert Fader Scale: If you activate this checkbox, the fader scale is inverted. To close the fader, you have to move it all the way up. If you move it down towards you, the level increases. For the Fader Module RM420-020 there is a matching front panel available.
0dB at Top: This option allows for Fader Modules to shift the scale by 10dB so the Fader has a gain of 0dB in the uppermost position. Please notice that the labelling of the front cover of the Console can not display this shift. It remains unchanged.
The Module ID of each module is unique in a RM4200D thus allowing the correct communication of the modules with each other. The configurable Modules of the RM4200D can be separated into the following groups:
| Fader Modules | Control Modules - Small, | Control Modules - Large, |
|---|---|---|
| 1 to 32 keys | 33 to 64 keys | |
| IDs F1 to F10 | IDs #C1 to #C12 | IDs #C1 to #C12 (2 IDs each) |
| RM420-020 | RM420-011 | RM420-010 |
| RM420-029 | RM420-013 | RM420-012 |
| + RM420-023 | RM420-026 | RM420-025 |
In a RM4200D Device, up to ten Fader Modules RM420-020 or RM420-029 can be used. These Fader Modules are automatically assigned the Module IDs #F1 to #F10 according to their order from right to left. The Fader Overbridge Modules RM420-023 are simply an extension of the corresponding Fader Module, they automatically receive the same IDs.
The Control Modules get assigned a Module ID #C1 to #C12 automatically on insert. Modules with more than 32 keys also claim the resources of the following ID.
Thus, in one Device either up to 12 small or up to six large Control Modules can be used. Combinations are possible as long as the sum of all claimed Module-IDs is not higher than 12. Thus, e.g. three large (six IDs) and six small Modules (six IDs) can be combined.
The address automatically assigned to a Module is displayed in the field Module ID.

The IDs #F1 to #F10 and #C1 to #C12 that are automatically assigned to the modules, must be assigned to the “correct” hardware modules when operating the RM4200D. It is the same when mounting a replacement module into an existing system. You can assign the Module IDs using the Maintenance Window. (see Set Module ID) | |

In theory, you can configure four different Main Modules RM420-010 within one Device, but it is not possible to build four mixers working independently within one RM4200D. Many basic resources and operating functions are designed for the operation of one mixer, especially when the bus system and the setup functions are concerned! | |
By selecting the Access Group for a module you define which other modules it will work with. All modules in the same Access Group work together, modules in different groups do not. You can choose from a maximum of four different Access Groups.
The concept is explained best with an example:
The Fader Modules are configured to Access Group 1, the central Control Module RM420-012 as well. If you press now the key with the function Access on the Fader Module, you can set the parameters for the selected Fader Channel on the Central Module.
Furthermore, if a central Overbridge Module RM420-013 is configured, in the display of which you want to show a Timer, you should choose a different Access Group, but not Access Group 1. Otherwise, the display of the Overbridge Module is controlled parallel to the display of the Central Module.
