Step 1: Configuring the Address
The first group of CVs you will want to change are those that set Tsunami’s
address:
CV 1, Primary Address
CV 17:18, Extended Address
Tsunami may be set up to recognize either the primary address (also called
the short address), which provides a range of 1 to 127 or the extended (long)
address, which has a range of 1 to 9999! Whether you use the primary or
extended address will first depend on whether or not your DCC system uses
extended addressing (not all of them do - if in doubt, see your command
station owner’s manual.) Second, it will depend on your preferences and
the numbering scheme you use for setting your decoder addresses. The
extended address has the advantage that you can use all four digits of
a locomotive’s road number for the decoder address making it easy to
remember. Be aware that some DCC systems do not support the full range of
available addresses.
Primary Address
To use the primary address, simply set CV 1 to the desired address between
1 and 127.
Programming Notes: Both the primary and extended address may be
changed at any time using service mode.
Some DCC systems will also allow the decoder address to be modified using
operations mode programming (consult your system manual for details).
Please note that when programming in operations mode, the following
restrictions apply:
If the decoder’s primary address is enabled (i.e., CV 29, bit 5 is 0),
only the extended address may be changed using operations mode
programming.
If the decoder’s extended address is enabled (i.e., CV 29, bit 5 is 1),
only the primary address may be changed using operations mode
programming.
Extended Address
The extended address is actually made up of two CVs, 17 and 18. Unless
you are an experienced user, you should not try to program these CVs
individually as a specific protocol is required in order for the DSD to accept
the new data (See the Technical Reference for details). Since most command
stations that support extended addressing will automatically generate the
correct protocol, simply follow their instructions for setting the extended
address.
