Multiplex operation of multiple amplifiers
If multiple light axes are arranged immediately adjacent to one another, mutual interference may occur, recognizable by a strongly fluc-
tuating display.
To avoid this undesirable behavior, up to 6 devices can operate in multiplex operation . To do this, it is only necessary to connect the
multi funct multifunction input (pin 2/ws-WH) of all participating amplifiers in addition to the voltage supply and switching signal.
Slaves Slaves Master
All multi funct multifunction inputs
(pin 2/ws-WH) are connected in parallel

For settings, see subfunctions:

Maximum 6 / minimum 2 units: 1 x 1 … 5 slaves.

Each unit can be either a master (
mA
or slave (
SL
).

The master also requires the information on the number of units connected in
parallel (
n
= 1 + number of slaves).

Each slave also receives an individual address 1 … 5 (max.)

The master generates a timing signal on pin 2 or on cable ws/WH.

Each slave switches on its transmitter for 1 ms depending on its address.

In multiplex operation, the cycle time is based on the total number of units:
cycle time = number of units • 1.5ms + 0.5ms.
