General information

General information
The converter operates based on the extended AS-i specification V3.0.
The signaling is made as Manchester-coded current pulses superimposed on the 28 V supply.
Since the power supply is used for communications, it must be decoupled with inductors in
order for the receiver to be able to decode the transmitted messages.
The yellow cable is the communication cable and provides the power to the converter and its
digital inputs. The black cable is the auxiliary power supply cable and provides power to the
digital outputs and the low voltage components of the converter including the fan.
The converter supports Single Slave and Dual Slave modes.
In Single Slave mode, the converter has an address in the AS-i network over which four bits
are transferred. In Dual Slave mode, each converter has two AS-i addresses over each of
which four bits are transferred.
In Single Slave mode, communication is realized in accordance with profile 7.F.E. In Dual
Slave mode, communication is realized in accordance with profiles 7.A.5 and 7.A.E.
Interface settings for commissioning
To configure the communication of the converter via AS-i, the following possibilities are
available for commissioning the converter:
