Correction to existing documentation
In the existing documentation, connection X1 / 2 is incorrectly documented as
"free / not connected". On the replacement device DC501-CS31-AD, the selec-
tion of the pin assignment of connector X1 is identical to the realization of
device DC501-CS31. Thus, the pin assignment described in this document is
valid for the replacement device and the existing device.
