6.1.1 Adjustment of the A-AI-2 connections
The assignment of the angular plug is designed for the most commonly used assignments of the
respective input signals.
As this is not a standardized assignment, your transmitter assignment may not correspond to the A-AI-
2 assignment.

In the angular plug the male contact 2 is directly
connected 1:1 with the socket. The A-AI-2 is
located between the male contact 1 (+) and the
jack contact 1 (-). The male contacts 3 and 4 are
used for the switching output.
If the 'Signal/GND'-line in your transmitter is not assigned to contact 2 and if the '-Ub'-line is not
assigned to contact 1, please do not forget to adjust the A-AI-2 angle-type plug and the external angle-
type plug accordingly. To do so open the A-AI-2 angle-type plug and exchange the wire of contact 1
and contact 2 against the wire of the contact representing the connection in your transmitter.
Then exchange and rewire the two contacts in the angle-type plug of your connecting cable.
