In this case, “[” and “]” are inserted according to their positions in the weighed data. They come to the positions before and after Position No.9 in the example. Consequently, the data becomes 2 bytes longer.

    15.2.4 Multi-Connection Mode A maximum of 26 UW/UX series balances can be connected to one personal computer at the same time. This is called “Multi-Connection mode.” To use the balance in this mode, prepare RS-232C cables in the number of balances connected, and the optional IFB-102A RS-232C Interface.

  • Page 97 Restricted Items in the Multi-Connection Mode Multi-Connection mode is not designed for each balance to independently send the data. This mode is for sampling the data by control of multiple balances with one PC. This is not the function to support multiple balances for sending the data separately. When multiple number of data and commands exist on the system at the same time, the balance may not operate normally.

    15.3 Communication Setting 15.3.1 Overview This menu is used to set the specifications for communication between the balance and a personal computer or electronic printer. This menu affects both the RS-232C and DATA I/O at the same time. For the instrument to be connected to the DATA I/O connector such as an electronic printer, select the communication setting of the balance to the default settings, which are menu items 76, 77, 83, 89, 92, 94.

    15.3.3 Format Set the balance output data format. The standard format for the Shimadzu electronic balance: Select menu item 77. The old output format for the Shimadzu electronic balance: Select menu item 78. The old output format is employed in the following models. EB-500, 5000, 280, 2800, AEL-1600, EB-50K (except -15) In this format, the number of the lowest place of menu item 70 is assigned to identify the balance.
