Any change of the Ethernet communication parameters become active only after an hw reset
RS485 port
RS485 communication circuit connections must be made using screened twisted pair cable observ-
ing the polarities; screening must only be connected to the end terminating at the RS485 interface
circuit pertaining to the monitoring unit.
It is recommended to terminate the line at the extremities of the same; this must be performed on the
RS485 line control unit and on the NA80 device placed at the furthest point connecting the specially
provided resistor; termination can be made by means a jumper between the F2-F3 terminals.
Termination resistors allow adjusting the impedance of the line, reducing the infl uence of the induc-
tive components of the same, which might compromise good communication.
