Configuration through the web interface

Ethernet IP Settings (for Digi Connect ES 4/8 SB with Switch only)

This section describes configuring and deploying Digi Connect ES4/8 SB with Switch devices in a

network.

The Digi Connect ES4/8 SB with Switch has two Ethernet interfaces:

 Ethernet Uplink: An uplink interface, that connects to the central data management

system network.

The uplink interface provides a single Internet Protocol (IP) address for all

communication to and from the devices at a single location. Network Address

Translation (NAT) and port forwarding provide seamless network access through the

Digi Connect ES SB SW for all Ethernet and serial devices at that location. DHCP or

static addresses are used for IP address assignment of the uplink interface.

 Ethernet Switch: A four-port switch that creates a Local Area Network (LAN)

The LAN switch can provide network connectivity to up to four network devices, in

addition to the Digi Connect ES SB SW itself, which provides four or eight isolated

RS-232 serial ports. The default IP address for the LAN interface of the

Digi Connect ES 4/8 SB with Switch is 192.168.1.1. The other network devices

connected to the Digi Connect ES 4/8 SB with Switch share this same Class C network

address scheme (192.168.1.x). A Dynamic Host Configuration Protocol (DHCP) server

is provided on this interface to allow dynamic assignment of devices as well.

The figure shows the location of the Ethernet Uplink and Switch ports on the product:

Because the LANs attached 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 one

location to another without needing to be reconfigured. The central 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.
