Ethernet Uplink IP Settings (for Digi Connect ES 4/8 SB with Switch)
The Ethernet IP Settings page configure how the IP address of the Digi device is obtained, either by DHCP or by using
a static IP address, subnet mask, and default gateway. For more information about how these settings are assigned
and used in your organization, contact your network administrator.
Ethernet IP Settings
The Ethernet IP settings for all Digi devices but Digi Connect ES 4/8 SB with Switch are as follows.
•
Obtain an IP address automatically using DHCP: When the Digi device is rebooted, it will obtain new network
settings.
•
Use the following IP Address: Choose this option to supply static settings. An IP address and Subnet mask must be
entered. Other items are not mandatory, but may be needed for some functions (such as talking to other
networks).
•
IP Address: An IP address is like a telephone number for a computer. Other network devices talk to this Digi device
using this ID.
The IP address is a 4-part ID assigned to network devices. IP addresses are in the form of 192.168.2.2, where each
number is between 0 and 255.
•
Subnet Mask: The Subnet Mask is combined with the IP address to determine which network this Digi device is
part of. A common subnet mask is 255.255.255.0.
•
Default Gateway: IP address of the computer that enables this Digi device to access other networks, such as the
Internet.
•
Enable AutoIP address assignment: With AutoIP enabled, the Digi device will automatically self-configure an IP
address when an address is not available from other methods, for example, when the Digi device is configured for
DHCP and a DHCP server is not currently available.
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.
