Installation - 2.17
20 mA Current Loop Interface
The DP1100 has two current generators (one for transmission and one for
reception), allowing active and passive type connections.
The terminals of the external cable must be connected to the following pins
of connector J1 (see figure 2.10) for 20 mA Current Loop communications:
