Addressing Ballasts
The addressing process can be triggered from the console using the
DALITEACHBYRND
command.
Syntax:
DALITEACHBYRND [LOOP] [ALL
or
UNASSIGNED]
The command can be executed to address all ballasts on the loop or just those that do
not have an address assigned yet. If all ballasts are not showing up during device
discovery but are responding to broadcast commands then there are likely ballasts
that have not been assigned an address. Running the command should expose these.
Readdressing everything is often the best solution as duplicate addresses may cause
problems that are difficult to discover.
NOTE:
Readdressing ballasts does not wipe out any grouping or scene information
that may be stored in the ballasts.
Constructing DALI Packets
For lower level troubleshooting, the DIN-DALI-2 console allows raw DALI packets
to be constructed and the responses displayed.
If the response from the ballast must be displayed on the console, the debug console
must first be enabled and standard polling of ballasts must be disabled. Without
polling disabled the console window fills with messages, making it difficult to see
specific ballast responses.
Enter the following commands to disable polling on both loops:
1.
DALIPOLL 1 STOP
2.
DALIPOLL 2 STOP
Enter the following commands to enable receive and transmit debug traces.
1.
DEBUGDALI RX ON
2.
DEBUGDALI TX ON
Once the console has been enabled any traffic on the DALI outputs is reported.
Pressing the DALI
TEST
buttons shows commands broadcasted to the ballasts.
The
SENDDALIPKT
command can now be used to communicate directly with a
specific ballast or group of ballasts. The paragraphs beginning on the following page
illustrate different ways to use the command.
NOTE
: When work is complete, the console must be disabled and polling must be
re-enabled. Without polling enabled, the DIN-DALI-2 does not report levels and
Ballast replacement is not possible.
To disable receive and transmit debug traces, use the commands
DEBUGDALI RX
OFF
and
DEBUGDALI TX OFF.
To enable polling on both loops, use the
commands
DALIPOLL 1 START
and
DALIPOLL 2 START.
