Installing the E2 Controller
Mount the E2 controller in a location suitable for Type 1 (NEMA1)
equipment.
1. Connect the I/O or MODBUS Network to one or all of the E2 RS485
I/O or MODBUS Network ports. (A maximum of 31 devices can be
wired to each I/O or MODBUS Network port.)
2. If the E2 is the beginning of all RS-485 I/O or MODBUS Networks,
set all three jumpers to the UP position. For MODBUS, set the
jumpers in the top-most position (MOD). For I/O Net, set the jumpers
in the middle position (I/O). For no termination, set the jumpers to
the DOWN position (NO).
3. Connect earth ground to one of the two ground terminals provided.
Use 12 AWG (preferred) or 14 AWG wire and keep as short as
possible (less than 12 inches preferred).
4. Connect 24VAC Class 2 to the power terminals.
5. Flip the power switch to the ON position. When 24VAC has been
applied to the board, the green LED will illuminate.
The E2 online help is the primary source front panel/interface users
will have to consult when seeking instruction on properties, screens,
menus, and troubleshooting of hardware/software problems. The
online help topics are designed to minimize the time the user would
otherwise have to spend searching through the manual to find
information. Press the  +  keys to open the General Help
menu.

Logging Into the E2 Controller
When the E2 is powered up for the first time, the user is automatically
prompted to enter setup information on a number of screens.
1. Enter “USER” in the Username field.
2. Press .
3. Enter “PASS” in the Password field.
4. Press .
Logging into and out of the E2 controller can be done at any time by
pressing the  key on the E2 keypad. If you are currently logged
out, pressing  will bring up the User Login dialog box. If you are
already logged in, pressing  will immediately log you out and
return you to the E2 home screen.
TCP/IP Setup
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 the E2
User Manual P/N 026-1614, E2 Ethernet Peer Communications
section for more information.
From the Main Menu:
1. Press  (System Configuration).
2. Press  (Remote Communications).
3. Press  (TCP/IP Setup) to advance to the TCP/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”. A Secondary DNS can also be entered if the
information is available.
Primary Gateway. Contact your network administrator 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”. A Secondary Gateway can also be
entered if the information is available.
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.
