Control Head Type 8681
ASInterface-Design
11.8. Programming data
The control heads have been configured as AS interface version with an extended address range (A/B slaves) for
62 slaves or optionally as an AS interface version for 31 slaves.
A change between the two configurations in the control head is only possibly by exchanging the electronic PCB!
If one control head is replaced with another control head having a different configuration in the AS interface field bus system (e.g. AS interface version 62 slaves (A/B-Slave) to replace a device with AS interface version
31 slaves), a configuration error will be generated at the master due to the different ID codes!
In this case (intentional replacement!), the current configuration must be re-programmed in the AS interface master. Please read the operating instructions of the used AS interface master!
AS-i address factory setting:
AS-i address = 0
