Service Button
Service
Button
The Service Button is used to trigger dedicated events. It is
important to distinguish different controller behaviors which
are elicited depending upon whether the Service Button is
pressed when the controller is powering up or when it is in
normal operation.
See the following dedicated events.
Pressing Service Button during Power-Up
If the service pin is pressed and then the controller is switched
on (while the service pin is still pressed), a reset to factory
delivery is performed.
The service button has to be pressed
until the green power LED goes out at least twice and is
switched on again.
Factory defaults are as follows:
•
The application is cleared from the controller.
•
The MAC address will be set to 0xFF, meaning that the
controller will now search for a new mac address (Auto- MAC
will be automatically triggered after controller power-up).
•
The maxMaster setting will revert to its default value of 127.
•
The Max info frames will revert to 10.
•
The device instance will revert to its default of 4194302.
•
The device name will revert to WEB-[ModelName].
•
The values of Auto MAC, Min MAC and Max MAC will be reset to
1 and 127
/64/35
, respectively.
Pressing Service Button during Normal
Operation
During normal operation of the controller, a short press (<
1 sec) of the Service Button will cause a Service Pin
Message (BACnet WhoAmI as a Private Transfer (SerialNo.
= 130)) to be sent.
