    INSTALLING LOAD CELL CABLES All digital scales using Cardinal Scale’s SmartCell DC digital load cells are connected with a daisy-chained CAN (Controller Area Network) cable. The load cell connection loop can begin at any load cell and may continue clockwise as shown or counter-clockwise if preferred. Note that in the tank/hopper example below there is not a connection between cells 1 and 2 and in the truck scale example, there is not a connection between cells 4 and 6.

    SETUP AND CONFIGURATION Digital Scale Setup and Configuration All digital scales using Cardinal Scale’s SmartCell DC digital load cells are connected with a daisy-chained CAN (Controller Area Network) cable. The load cell connection loop can begin at any load cell and may continue clockwise as shown or counter-clockwise if preferred. Note that in the tank/hopper example below there is not a connection between cells 1 and 2 and in the truck scale example, there is not a connection between cells 4 and 6.

  • Page 27: To Begin 225D Setup And Configuration

    To Begin 225D Setup and Configuration Addressing Cells Each cell has a serial number (S/N) marked on the cell. This is an 8-digit hexadecimal number. It is also known as the Cell ID. Each Cell ID must be matched with a cell address. In the tank/hopper example, the addresses would be 1-4.

  • Page 28: End Nodes

    End Nodes The 225D indicator also needs to know where the scale starts and ends. The START NODE is the cell that connects to the 225D. The END node is the last cell in the daisy chain. In the tank/hopper example, the START node is #1 and the END node is #2. In the truck scale example, the START node is #4 and the END node is #6.
