Specifications
TCP/IP
E2 controller versions 2.10 and later communicate
between controllers using the TCP/IP protocol. TCP
Port 7238 is the default for connections established
between the controllers. All peer communications oc-
cur over this port.
7.4. Ethernet Network
Layouts
The two types of network options for E2 control-
lers using Ethernet communications are:
1. “Closed Network” - E2 devices are
not con-
nected
to a store’s LAN. (The only devices
on the network are the E2 controllers them-
selves.) This network type is used if there is
no need to integrate the network into the
company’s intranet.
2.
“Open Network” - E2 devices
are connected
to the store’s LAN. (Devices on the network
include E2s and other Ethernet-TCP/IP
devices.) This network type is used if the
network will be connected to the store’s
LAN.
The E2 peer Ethernet network facilitates commu-
nications between E2 controllers. These include at
least the following:
• Routing of messages between external entities
such as UltraSite, InSite, Site Manager, and
non-gateway E2 controllers.
• Distribution of global data and other network
variables such as system time, controller identi-
fication, etc.
• Communication between E2 controller applica-
tions such as Remote Login and Remote File
Services.

NOTE: Contact your IT Network Adminis-
trator for setup parameters for both closed
and open networks.
NOTE: The gateway E2 is the E2 controller at
a remote site to which UltraSite directly con-
nects. It is through this E2 that UltraSite com-
municates with the other controllers (defined
as the “non-gateway” E2s and external entities such as
UltraSite, InSite, Site Manager, etc.).
