Operation Modes
The output signals are always the same, independent of the mode of operation, but the inputs
may have different functions. The mode can be selected by the 8-position DIL-switch S2. The
index pulse (Z) will only be converted to TTL-level, but not be affected by the mode setting.

This mode of operation requires that one of the two inputs is in LOW state while the other
input line receives the pulses.
