Power supply and RS485 from screw terminals
There is RS485 communication in the
7, 8, 9 screw terminals as shown in the
following figure.
The electric connections for power
supply and RS485 can be made by
using either the terminals or the bus for
the Seneca DIN rail.
The default configuration for Z-LINK1 module: DIP-switches are in position 000000. DIP-
switch status defines the functioning modality and module radio communication
parameters.
In the following tables: box without circle means Dip-Switch=0 (OFF state); box with
circle means Dip-Switch=1 (ON state).

The module Z-LINK1 has the RS232 communication port by RJ10 or screw terminals 4, 5, 6, 1
as shown in the following figure. The RJ10 port is the RS232 physical replica of the RS485
signal via radio.
