Description and action
3A1579Rev1.4
If there is no module connected to the serial port you have selected or
BU-Config cannot communicate with the module the following message is
shown:
Click OK to acknowledge the message and check the power to the mod-
ule, the comm port selected and the serial cable/connections to try again.
If the module connected to the serial port has the same unit address as
one already in the system, BU-Config will show the following message if
either the unit or the module does not support secondary addresses
(i.e., either one is not transmit only):
Click OK to acknowledge the message and return to the previous screen
without loading the module.
If the module connected to the serial port has the same unit address as
one already in the system but both the unit and the module support
secondary addresses, BU-Config will show the following message:
Click OK to acknowledge the message and continue loading the module
or Cancel to return to the previous screen without loading the new unit.
If the module connected to the serial port has the same secondary
address as one already in the system, BU-Config will show the following
message:
Click OK to acknowledge the message. If you choose to continue loading
the module check that you have the correct module connected. The new
unit will retain the module’s unit address and will be assigned the lowest
unused secondary address for that unit address.
If the module connected to the serial port has a different system address
to the one already assigned to the system, BU-Config will show the
following message:
Click OK to continue loading the unit or Cancel to return to the previous
screen without loading the module configuration.
If you choose to continue you will be asked whether you want to modify
the system address of the system to match that of the module you are
loading:
Click Yes to change the system address to match the unit you are loading
or No to keep the existing system address already being used by other
units in the system.
If you choose to change the existing system address all the existing
modules must be reprogrammed before the update is complete.
If you choose to keep the existing system address you must program the
unit you are loading so that it will have the same system address as the
rest of the system.
9. You can now configure the new unit.
