4.5.12.11 Deleting parameters
Various parameters can be stored in the bus controller's flash memory:
•
Communication parameters
•
Vendor-specific parameters
•
Application parameters (device profile)
•
Fixed transfer rate
Deleting these parameters using switch position 0x90 returns the bus controller to its factory settings.
Clearing the parameters listed above
1. Turn off the power supply to the bus controller.
2. Set the node number to 0x90.
3. Turn on the power supply to the bus controller.
4. Wait until the "MS" LED starts blinking green (100 ms on / 200 ms off). The node number switch must be set
to 0x00 and then back to 0x090 within this time window of 5 seconds (rotate the top switch).
5. Wait until the "MS" LED blinks with a red double-flash (parameters have been cleared).
6. Turn off the power supply to the bus controller.
7. Set the desired node number (0x01 - 0x7F)
8. Turn on the power supply to the bus controller.
9. The bus controller boots with the set node number and automatic transfer rate detection.
