ACC2 Decoder - Station Assignments

When multiple decoder output modules are present, the range of station numbers allowed on each one can be changed, or "mapped." This allows you to assign more than 75 stations to a decoder output module when necessary, to take advantage of the field wiring layout, as long as another module is present in the controller.

Each output module provides 75 stations when it is installed. If you need more than 75 stations on a single two-wire path, or on paths from a single module, you can reassign the station numbers from the other module(s) to the first module, and so on.

Check the box to enable station assignment changes, and click to confirm.

Each module will be shown with the range of station numbers assigned to it. At first, each will have 75 stations.

Select the Upper field for Decoder Module #1 to adjust the Upper station range up or down. As you adjust it, you’ll see the range of Decoder Module #2 changing by a corresponding amount.

If you set the range of the first module to less than 75 stations, the remaining stations are available to be assigned to module #2.

If you set the upper range of the first module higher than 75 stations, those stations are removed from module #2.

In this way, you can specify how many stations are available on each decoder output module.

You can click the Reset soft key to reset the modules to 75 stations each.

The more stations you assign to a single decoder output module, the higher the standby current draw on that module. This means that you may not be able to run as many active stations simultaneously with very high station counts on a single module.
