WLAN Call Button
For energy-saving reasons, the CallButton is powered off at standby time (except LC display and alarm clock circuit). On occurence of one of the following events it wakes up and connects to Rabus Server via TCP/IP over WLAN:
- Push Button pressed (“T”)
- Barcode scanned (“S”)
- External input trigger (“A”)
- Alarm timer (“W”; frequent event every 5 seconds to 255 minutes)
- Firmware update over WLAN completed (“U”)
- Configuration update over WLAN completed (“C”)
After sending a communication telegram for the appropriate event the CallButton waits for a response from Rabus Server or the webserver, resp. with new display contents and lamp state. After reception it powers off. During standby, the CallButton is not able to communicate with the host. Thus, a communication transaction is always initiated by the CallButton, never by the server.
Assembly
The Call Button is designed for easy installation (without external power supply) and long maintainance-free operation time. It contains a long-life battery and a sophisticated power management, so that it can be operated several years - depending on duty cycle - without battery change. The Call Button operates with a proprietary firmware lacking of a standard operating software in order to go with as few as possible resources.
