Internet connection via Ethernet cable
In order to display the data measured and processed by the Datalogger in the portal, it is necessary to
connect to the internet via LAN cable and open the following router ports:
VPN ports: 22 and 1194
HTTP ports: 80
DB ports: 3050
FTP ports: 20 and 21
The local network of the device is configured for DHCP, and it is not necessary to activate any
communication port on the router. If you want to set a fixed network address, this must be provided at the
time of ordering together with the gateway address.
10.4.7.4.
Connecting the power supply and battery pack to the
Datalogger
Once the RS485 Half Duplex cable has been connected, power the Datalogger by connecting the power
supply unit (supplied with the datalogger) to the MAIN PWR input (12V DC - 1A).
In order to prevent possible voltage drops and/or power failures, it is recommended to also connect the
battery pack, which is supplied with the datalogger. The battery pack should be connected to the +V
bat
and
GND inputs of the BATT PWR connector, positive and negative respectively (i.e. red to the +V
bat
input and
black to the GND input).
The battery pack (ZSM-UPS-001) can be purchased separately.
