Emerson E2 Manuel D’Utilisation

You can choose between an internal modem (one that 

is mounted directly on to the E2 circuit board (via the 
PC-104 slot in previous generation E2 circuit boards) or 
an external modem. If you have a modem, navigate to 
the COM3 Modem Port field and select Internal 
Modem. Press 

 (LOOK UP) for the Option List 

Selection screen.

The TCP/IP screen is where you enter the information 

necessary to allow Ethernet connection to this controller. 
If this site uses Ethernet box-to-box, you will need to enter 
a TCP/IP address and a group name to allow all E2s on 
site to communicate as a group. See Section 7, E2 Ether-
net Peer Communications for more information.

IP Setup screen

E2 units may be configured to communicate across an 

Ethernet computer network using TCP/IP protocol. To 
enable Ethernet communication, you will need to enter IP 
address information for the E2 in the Serial IP screen.

IP Address   The IP Address field sets the network 

address for this E2. Other network devices (such as 
PCs running UltraSite) will communicate with this 
E2 by sending information to this specified address. 
Contact your network administrator to determine 
what IP address to enter.

The IP Address always consists of four numbers 
from zero to 255, each of which is separated by a 
period. Enter the address in this format.

Subnet Mask   Contact your network administrator 

to get the correct subnet mask value, and enter it in 
this field.

The default value, “255.255.255.0”, is the subnet 
mask commonly used for small networks.

Primary DNS   Contact your network administrator 

to see if a Primary DNS value is required for this E2. 
If so, enter the Primary DNS address supplied by 
your administrator in this field. If not, leave this field 
set to “0.0.0.0”.

Secondary DNS   Contact your network administra-

tor to see if a Secondary DNS value is required for 
this E2. If so, enter the Secondary DNS address sup-
plied by your administrator in this field. If not, leave 
this field set to “0.0.0.0”.

Primary Gateway    Contact your network adminis-

trator to see if a Primary Gateway value is required 
for this E2. If so, enter the Primary Gateway address 
supplied by your administrator in this field. If not, 
leave this field set to “0.0.0.0”.

Secondary Gateway   Contact your network 

administrator to see if a Secondary Gateway value is 
required for this E2. If so, enter the Secondary Gate-
way address supplied by your administrator in this 
field. If not, leave this field set to “0.0.0.0”.

DHCP Enabled   Dynamic Host Communication 

Protocol (DHCP) is a protocol that assigns a dynamic 
IP address to devices on a network. With dynamic 
addressing, a device could have a different IP address 
every time it connects to the network. When set to 
Yes, DHCP Enabled keeps track of IP addresses and 
enables a new IP device to be added to a network 
without having to manually assign it a unique IP 
address. DHCP supports a mix of static and dynamic 
IP addresses.
