If the LT-4100 system is connected to a local network as illustrated in Figure 111, where a DHCP server is
already available, then the LT-4100 system must be configured to either DHCP client or Static mode. The
Static mode can be used, if it is required that the IP-address of the LT-4110 Control Unit must never change.
The LT-4100 system has two reserved network ranges, which are documented in Table 24.
IMPORTANT
: Do not connect the LT-4100 System to any external IP networks, which are not trusted. The
LT-4110 Control Unit has Firewall rules configured on all Ethernet ports to avoid unwanted
IP traffic.
DHCP client
The DHCP client mode is the configuration of the LT-4110 Control Unit from the factory. The DHCP client
mode must be used, if the IP network already has a DHCP server available.
