This mode (only DS23x) allows to evaluate a dual channel system, equipped with two identical
RS422/TTL incremental encoders. The encoder must be performed in accordance to chapter
5.4 .

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] and [X7 | SINCOS IN 2] have no function.

Both control inputs (Control1 and Control2) are available for control signals at
[X10 | CONTROL IN].
