2 Configuring the DALI-to-DMX bridge
This chapter explains how to set the bridge’s DMX network resolution to 8 or 16 bit and how
to configure the bridge for a single multi-master environment by way of DIP switches??? . Fur-
thermore, it shows you how to map DALI addresses to DMX addresses using DALI commands.
2.1 Setting the DALI address range
To set the DALI address range that must be mapped to DMX addresses, use the following se-
quence of DALI commands:
• INITIALIZE: indicates the start of a command sequence
• PHYSICAL_SELECTION: informs the DALI master that a configuration is coming up
• PROGRAM_SHORT_ADDRESS: sets the DALI first or last of the range of DALI ad-
dresses. xx stands for the two-digit address and can range from 0 to 63 or from 1 to 64.
• TERMINATE: indicates the end of a command sequence
Repeat this command sequence to set the second address: it is irrelevant whether you set the
start or the end address first, as the DALI-to-DMX bridge will subtract the lowest address from
the highest one in order to get the range of DALI addresses that will be mapped to DMX ad-
dresses. The lowest DALI address is mapped to DMX address 1.
2.1.1 Output DMX channel replication
128 DMX channels are sent out (broadcasted?) by default; some channel configurations are
rounded down to the highest multiple of the x number of channels for that bridge. For example,
a 3-channel DALI-to-DMX bridge has 126 DMX output channels.
This means that if you have a 4-channel DALI-to-DMX bridge, and the network resolution has
been set to 8 bit with DIP switch 1, the 4 output channels are replicated 32 times:
If DMX network resolution has been set to 16 bits, a DALI ballast uses twice the number of DMX
channels. The maximum number of DMX channels is still 128, however, meaning the number
of times a DLAI ballast can be replicated is half the number in 8-bit mode. REPHRASE!!
DALI ballast 1 2 3 4 1 2 3 4 1 ... 3 4
DMX channel 1 2 3 4 5 6 7 8 9 ... 127 128
