LAN connection with single Logger
It is the simplest configuration. The data logger is connected to a PV system and a
computer installed with monitoring software. In this case, data logger is connected to
computer directly by “crossover” Ethernet cable.
Before connecting to a computer, data logger must be set with IP address manually by
other computer and method.
User can also use a router with DHCP function in between computer and data logger.

Fig.54 System configuration with single logger in LAN
LAN connection with multiple loggers
In this configuration, there are more than data loggers in the system. If a HUB with
DHCP function is used, user has to setup the IP address of data logger as previous
section. However, we recommend using a router with DHCP function instead of hub.
Computer installed with monitoring program such as PV Monitor can monitor multiple
data loggers in the same time.
