The weight transmitter menu is used to configure the DeviceNet Module.
1. Reboot the weight transmitter.
2. Press the key while the display check is in progress to access the menu:
Parameter Descriptions
Enables HUB mode Sets the  of the module
In HUB mode, identifies the primary scale in the network to set the Parameters
Selects the baud rate (10 Kb/s to 1 Mb/s)
If  =  or , RS-485 baud rate is automatically set to 115,200 and scale address = .
Functioning Modes
