Infrared addressing
The AS-i module also offers the option of infrared addressing with the
addressing unit AC1144.
The AS-i communication (yellow cable) must be switched off
during the infrared addressing. To do so, disconnect the master.
Supply the slaves with voltage via the AS-i power supply. Addressing is
carried out via the IR addressing cable E70211.
When the ifm AS-i power supplies SL are used the communication can
be deactivated via a plug on the power supply.
