4 Setting Up

4.3.2 Setting the operating mode

Attention! The following details only apply for the S7 default position (S7 = 0)!
The DIL switch S0 is used to set the operating mode of the electrical port CH1.
The DIL switches S1 and S2 are used to set the operating mode of the optical port CH2.
The DIL switches S3 and S4 are used to set the operating mode of the optical port CH3.
S3 and S4 do not have a function on OLMs with only one optical interface.

4.3.2.2 Setting the operating mode of the optical ports (CH2, CH3)
The operating mode can be set individually for each optical port. Combinations of the operating modes "Line with
optical fiber link monitoring" and "Line without optical fiber link monitoring" are also possible.
Note that the operating mode of the two optical ports which are connected by the fiber line must always have the
same settings! The operating mode "Redundant optical ring" must always be set at both of the optical ports.
