2 – FIXTURES LAYOUT, MANDATORY LIMITS
Here below some typical layouts, that can be used to connect ADSI fixtures to a NODO-MASTER.
-
"Stand-alone 1" layout: Power supply unit, NODO-MASTER: this is the simplest layout, the power supply unit and NODO-MASTER
supply only one fixtures section.
-
"Stand-alone 2" layout: Power supply unit, NODO-MASTER, two fixtures sections: this layout is used e.g. when NODO-MASTER is
in the middle of a section
-
"Master-Slave" layout: Power Supply 1, NODO-MASTER 1 for Section 1; Power Supply 2, NODO-MASTER 2 for Section 2...: in case
of extremely long sections (longer than the NODO-MASTER limits) permits to synchronize each section to the others. NODO-
MASTER 1 is the "master" (the only one recognized by DALI/DMX environment, so occupying addresses on the bus), all others are
set as "slave" (they don't occupy addresses on DALI/DMX bus).
and the section. See Table 1 for advised gear power.
layout, the number of "slave" NODO-MASTER has to be included into the 25 fixtures. So e.g. if there are 3 "slave" NODO-MASTER
connected to the master, in the master section the maximum number of fixtures is limited to 25-3=22. See also Table 1 for limits.
between them, being L is the cable length between NODO-MASTER and 1st fixture of the section (in case Stand-alone 2, L=LA+LB)
and K the total length of modules (in case Stand-alone 2, K=KA+KB ), see Table 1 here below to determine K.
