  • Page 19 The string of desired output quantities is established by typing in the desired order, the corresponding alphanumeric characters which appear on Menu (= 78012tce HD2003 Factory Default, also for ModBus Registers) (= 78tce HD2003.1 Factory Default, also for ModBus Registers). The string may consist of 12 alphanumeric characters at most that correspond, with the selection of 5.

  • Page 20: Parameter Setup

    For instance: (HD2003 Model). If the string of the output quantities is set to 78012tc, that is to say with seven quantities, it means it is necessary to use two ICP DAS I-7024 ® modules, the first one with address 00 e and the second one with address 01.

When you place your order, you can combine the two optional quantities q3 and q4, with two 0-1V external sensors connectable to the Anemometer. Thus, two additional measurements are added to the output quantities already available in the HD2003.
