Ethernet Uplink: An uplink interface that connectsto the central data management system
network.
Theuplink interface provides a single Internet Protocol (IP) addressfor all communication to
and from the devices at a single location. Network AddressTranslation (NAT) and port
forwarding provide seamlessnetwork access through theDigi Connect ESSBSWfor all
Ethernet and serial devices at that location. DHCPor static addresses are used for IPaddress
assignment of the uplink interface.

Ethernet Switch: Afour-port switch that creates a Local Area Network (LAN).
TheLAN switch provides network connectivity for up to four network devices, in addition to
the Digi Connect ESSB SWwhich providesfour or eight isolated RS-232 serial ports. The
default IPaddressfor the LANinterface of theDigi Connect ES 4/8 SB with Switch is
192.168.1.1. Theother network devices connected to the Digi Connect ES 4/8 SB with Switch
share this same Class Cnetwork addressscheme (192.168.1.x). A Dynamic Host Configuration
Protocol (DHCP) server isprovided on thisinterface to allow dynamic assignment of devicesas
well.
Thefollowing figure shows the location of the Ethernet Uplink and Switch ports on the
product:
Because the LANsattached to each Digi Connect ES 4/8 SB with Switch are typically not connected to
each other, equipment can have static network addresses and be moved from onelocation to another
without needing to bereconfigured. Thecentral data management system can easily communicate
with the equipment by addressing the appropriate Digi Connect ES 4/8 SB with Switch device. The
Digi Connect ES 4/8 SB with Switch uses NAT and port forwarding to make the connection.
See Configure theEthernet interfacefor Connect ES4/8 SBwith Switch for instructionson configuring
the network topology just described.

Thesesteps apply to a single Digi Connect ES 4/8 SB with Switch and its connected Ethernet and
serial devicesand must be performed for each Digi Connect ES 4/8 SB with Switch deployed.
