Figure 96 Default setting of DIP switches for MIM-1E1/MIM-2E1/MIM-4E1 and
MIM-1E1-F/MIM-2E1-F/MIM-4E1-F modules
Description of DIP switch settings is given in the following table for
MIM-1E1/MIM-2E1/MIM-4E1 and MIM-1E1-F/MIM-2E1-F/MIM-4E1-F modules:

CAUTION:
■ It is recommended to select the DIP switch of MIM-1E1/MIM-2E1/MIM-4E1 and
MIM-1E1-F/MIM-2E1-F/MIM-4E1-F modules in this way: when connecting
75-ohm cable, flip BIT1-8 to ON, and when connecting 120-ohm cable, flip
BIT1-8 to OFF. Positions of DIP switches can only be changed by the trained
personnel.
