1. Functional Description

The GS202 is an Encoder Switch with 20 encoder inputs, 2 encoder outputs and 2 x 6 control
inputs. Depending on the configuration of the control inputs, the device switches thorugh the
signal on the input (IN 1 – 20) to the corresponding output (OUT 1 – 2).

Both outputs operate independently of each other. The output has to be configurated via the
corresponding control input. To each output only one of the 20 inputs can be allocated.

Via a 5-bit parallel signal (BIT 0 – BIT 4) a special input (e. g. IN 16) will be selected. This input
will be assigned to the output (e. g. OUT 2) by a pulse on terminal SET.

If the bit pattern is 00000 or in case of an invalid 5-bit-parallel signal, no input will be assigned
to the output. During this process all tracks (A, B, Z) of the output are set to LOW and all
inverted tracks (/A, /B, /Z) are set to HIGH.

Illuminated LEDs indicate the respective input assignment. Green LEDs signalize output OUT 1,
yellow LEDs signalize output OUT 2.
