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 occur over this port.

Ethernet Network 
Layouts
The two types of network options for E2 controllers 
using Ethernet communications are:
1.
“Closed Network” - E2 devices are not connected 
to a store’s LAN. (The only devices on the net-
work are the E2 controllers themselves.) This 
network type is used if there is no need to inte-
grate 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 con-
nected to the store’s LAN.
NOTE: Contact your IT Network Administra-
tor for setup parameters for both closed and 
open networks.
The E2 peer Ethernet network facilitates communica-
tions 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 iden-
tification, etc.
Communication between E2 controller applica-
tions such as Remote Login and Remote File 
Services.
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 Ultr-
aSite, InSite, Site Manager etc.).
