Assigning a Converter Address
The 6021 Control Unit can only put out the addresses
1 - 80. A converter address 1 - 80 must be assigned in
order to be able to Control locomotives with decoder
addresses greater than 80.
Example: A locomotive with a "programmable mm2
decoder" is set for address 146. You can give this
locomotive a converter address (1 - 80) so that it can be
Controlled with the Control Unit.
With an mfx locomotive there is the advantage that you
do not have to delete the preset Motorola address (if this
address is already occupied). Instead, you can also use
this locomotive by assigning a free converter address.
!
A converter address may not be used for multiple
locomotives!
All converter addresses not in use are managed by
the Connect 6021 as standard Motorola addresses. All
locomotives with a Motorola address from 1 to 80 can
be Controlled from the Control Unit without changing the
converter address.

Changing the converter address is not transmitted to
the locomotive decoder!
