Master-slave circuit
In a master-slave circuit, EASY DMX, OT EASY 60 II or DALI EASY III control units
can be connected together. The devices use a master-slave communication concept
to synchronize with each other.
CAUTION!
Master-slave connection lines conduct protective extra-low voltage signals!
•
Do not route together with power supply or lamp lines.
•
Ensure that the master-slave connection lines are sufficiently insulated against the
power supply or lamp lines.
System limitations
In order to set up a master-slave circuit, the following rules have to be observed:
•
Extension of more than one EASY DMX is allowed; the limit of 64 independent light
points must not be exceeded.
•
Max. number of DALI EASY III and OT EASY 60 II and related limitations must be
observed. See separate instruction sheets of DALI EASY III and OT EASY 60 II.
•
Max. total EASY line length (without EASY system coupler): 100 m
•
Max. 50 m to pushbutton coupler.
•
Every EASY system requires exactly one master control unit in the complete sys-
tem. Configure all other control units as slaves.
•
Max. number of independent light points (see examples in the following table):
• EASY system: 64
• EASY DMX 64x4 SO: 64
• EASY DMX 32x4 SO: 32
• EASY DMX 16x4 SO: 16
• OT EASY 60 II: 1
