Installing Elise 2 Server (AIWS Hardware)
RS422 Communication with external unit
Figure 180: Depending on software application the RS422 port is used or not. If it is used, the
connector J6 is connected to the external unit as shown in the figure below.Connection of
external unit via the RS422 port.

communication
Connection of AUX inputs and AUX outputs
The application of the inputs and outputs are software dependent.
Two digital inputs and two digital outputs can be connected via J16. The outputs are of
open-collector type and the output signals are dimensioned for 100 mA at max 12 V.
A pull-up resistor should be connected to the output as shown in
Galvanic isolation of the inputs and outputs is provided by using a separate power supply. When
galvanic isolation is not needed, supply voltage can be taken from the Elise 2 Server (AIWS
Hardware) circuit board by connecting J16-1 to J5-3 and J16-6 to J5-4.

The inputs IN1 and IN2 are active when they are connected to 12 V. When the output OUT1 is
active, the potential in point A in
