Encoder interface X2
The encoder interface of the SIMOLINK Pulse Generator is the 9-pin,
SUB D socket with screw locking mechanism (UNC) on the front of the
housing. Two RS422 drivers each supply two signals per pulse output,
one signal with non-inverted signal level and one signal with inverted
signal level. The driver voltage supply circuit is isolated from the 24 V
supply for the module.

Schematic of output circuit (connector X2)
The two operating modes "90° pulses" and "100 kHz signal" are
selected via a jumper in the encoder connector. The 90° pulses setting
is the default and is activated when pin 1 in the encoder interface is
unused.
