**** A safety level can only be achieved in these cases, if it is physically ensured that
there only can be only one direction of rotary and linear movement. This can be realized for
example by using a self-locking gearbox.
This mode (only DS23x) allows to evaluate a dual channel system, equipped with two identical
encoder types. Therefor a combination of two incremental single channel HTL encoders is used. The
connections of both encoders must be performed in accordance to chapter
5.5 .

A DS230 variant reproduces selectively the input frequency of Sensor1 or Sensor2
to the splitter output [X4 | RS422 OUT].

The inputs at [X6 | SINCOS IN 1], [X7 | SINCOS IN 2], [X8 | RS422 IN 1] und [X9 |
RS422 IN 2] have no function.

Please note, that no more Control1 and Control2 inputs for external commands are
available, when connecting both encoders to terminal X10] pin 2 and 4.
