Start Address - DMX soundlight 7044B-H Operating Manual

The DMX start address can be selected using the start address switches. Also, special
programming of the interface is performed using the adress range beyond 512 (see chap-
ter „Setup"). The adress 000 is not a valid start adress and will be decoded as 001 instead.
DALI adressing cannot be changed and is fixed from 1 thru 4* (64). The same applies to DALI
group adressing.
*= pre-configured to 4 addresses (data slots) . User-reprogrammable zo 4...64 addresses / data slots (see chapter „SET-
UP" below).
Please note, that DALI is much, much slower than DMX: controlling two DALI addresses simultan-
eously requires about the same time as transmitting a complete DMX telegram containing 512 data
slots. That's what the DALI guys call „DALI Delay".
Thus only up to four individual DALI units may be controlled simultaneously without a too big delay.
The decoder, however, can be configured to output data for up to 64 adresses sequentially - but
for the reason outlined above the default setting is four (4). If more units are to be controlled simul-
taneously we recommend to change to group address setting, or use multiple decoders and multi-
ple DALI links in parallel. We also recommend to re-program connected DALI responders to a fade
time of at least 0,7 sec (fade time parameter set to 1 or 2) to allow a smooth response. You may do
so using your preferred DALI programmer (or our USB-DALI tool).
The DALI protocol can be set to individual adressing or group adressing mode using adresses 1
thru 4 (64). DALI data are derived from the incoming DMX data. Please note that the maximum in-
tensity -as used by DMX- is 255, whereas the maximum intensity on the DALI line is 254. (In the
DALI standard, value 255 is reserved for "MASK" [no operation]). Thus the maximum level is clip-
ped from 255 to 254*.
The DALI output is intended for connection to a DALI bus system. The DALI bus must be fed from
a DALI power supply (DALI PSU) and may be loaded with up to 64 bus participants. If required, ad-
ressing on the DALI bus must be performed using a suitable addressing tool (e.g. our USB-DALI in-
terface). The 7044B-H does not perform any adressing of bus participants by itself.
*= pre-configured to 254 . User-reprogrammable zo MASK value 255 (see chapter „SETUP" below).
The decoder status is signalled using three LED indicators:.
green: on when DMX signal present
blinks when DMX signal present but DALI bus fails or is smissing
red: ERROR
blinks when DMX signal is missing or contains invalid data
yellow: Steady:
random blink: activity
normally off
DALI Bus missing or unpowered
