This version allows an additional indoor station to be added in a unit as extension unit.
The second LAN connection of an indoor station is not PoE-capable. That is why a 24 V power
supply is required for the additional indoor station.
Use the following steps to add additional indoor stations:
1. Searching for devices in the "Smart Access Point".
– Connect a PC with the "Smart Access Point".
– In the main menu of the "Smart Access Point", change to the "Door communication"
function.
– Search for all devices in the building network including the master indoor station.
Switch to the 1st indoor station
2. Prepare the 1st indoor station (Master) for the operation of an indoor station.
– In the 1st indoor station change to the "System settings" / "Network settings" function.
– Set a fixed IP address and the sub-net mask in the "Network settings" for the LAN
connection "LAN 2".
– Disable the "Obtain IP address automatically" function.
– IP address: 192.168.1.200
– Sub-net mask: 255.255.255.0
Change to further indoor stations
3. Configure the additional indoor station (extension unit) for operation.
– Change to the "Settings" / "Local settings" function in the additional indoor station.
– Set the following points in the "Local settings" function:
