Quick adressing
1. Press the “Address” button until the green “Power” LED is no longer illuminated.
LED flashes in accordance with the previously set address.
2. Set the address by pressing the “Address” button the corresponding number of
times (1-16).
3. The green LED flashes in accordance with address that has been entered (1-16). If
the address is not correct, then this can be reset in accordance with Step 2.
4. Confirm the address setting by pressing the green “Adaption” button.
If no confirmation occurs for 60 seconds, then the address procedure is ended. Any
address change that has already been started will be discarded.
The resulting BACnet MS/TP and Modbus RTU address is made up of the set basic
address plus the short address (e.g. 100+7=107).
