Connections - with converter:
When buying a converter solution, the enclosed manual will explain how the connec-
tions must be made. Please follow this manual carefully.
As an example, the connection of the Black box: ME 800A-E (current loop) will be
described in the following by Table 3.

The ME 800A-E must be set up as a DCT with no RTS/DTR control.
The interconnection cable is a 4 wire twisted pair telephone cable with or without
shield. The shield improves noise immunity but reduces the maximum communica-
tion distance.
