The Delta system itself offers in total 5 addresses (4 + 1 handheld "Delta Pilot") to play with. But the Delta decoders in the locomotives offer many more addressing possibilities than those 5 supported by the Delta system.

Here we list the usable Digital addresses that can be set on the Delta decoder. Please note that there are 2 tables, one for newer Deltas with DIP-switches, and one for the older Deltas with solder bridges.

The Delta switches/bridges correspond to the DIP-switches 1, 3, 5, and 7 on a Digital decoder.  

It is also possible to modify the Delta to use all 80 addresses with some re-soldering of the circuit, but this is beyond the scope of this page. For more information on how to get all 80 addresses, please look at Dr König's digital site...

There is also a difference between the older and newer decoders, and it is that the older decoders automatically detect if you run digital or analog operation, and the newer ones require all DIP-switches to be set to the "off" position to run in analog operation.

Address table for Delta decoders with solder bridges

This table presumes you have the Delta decoder positioned with the solder bridges towards you. The solder bridges are numbered from left to right. Please note that the addressing order is reversed compared to the DIP-switch Delta decoder.
