CONTROLLER IP ADDRESS
The controller’s local network IP address is used to identify the Omni LTe controller on the network. To view and
assign the controller’s local network IP address, from the Set Up menu, press the 6 (MISC) key. Using the down
arrow key (↓), scroll to the following menu item:
IP ADDRESS
192.168.0.101
The format of the IP address is a 32-bit numeric address written as four numbers separated by periods. An IP
address has two components, the network address, and the host address. The first two numbers (e.g. 192.168)
represent the Class B network address and must be the same as the first two numbers of your local network. The
second two numbers (e.g. 0.101) identify a particular host on the local network and may be assigned at random as
long as each device on the local network has a unique address. Each number can be 0 to 255. Enter the 1, 2, or 3
digit number followed by the “#” key to move to the next number. After the 4
th
number has been entered, press the “#”
key to store the IP address.
CONTROLLER PORT NUMBER
The controller’s local network port number identifies the logical channel to the Omni LTe controller. For example, port
80 is used for HTTP traffic; the controller’s local network port number is used for Omni-Link traffic. To view and
assign the controller’s local network port number, from the previous Setup item (IP ADDRESS), press the down arrow.
PORT NUMBER 4369
0-65535
In most installations, the default port number can remain the same. Port numbers range from 0 to 65535. To change
the port number, enter the new port number followed by the “#” key to store the port number. Port numbers 0 to 1024
are reserved for designated services and should not be used.
ENCRYPTION KEY
Encryption and decryption of data between the Omni LTe controller and the connected device is based on the
Advanced Encryption Standard (AES) using a 128-bit cryptographic key. A unique encryption key is randomly
assigned to each Omni LTe controller at the factory (no records of these keys are kept at the factory). It may be left
the same (recommended) or it may be changed as desired. To view and assign the encryption key, from the previous
Setup item (PORT NUMBER), press the down arrow key.
ENCRYPTION KEY PT 1:
6F-1B-26-A2-FF-D9-E4-12
This key consists of 16 bytes (that is 16 2-digit values from 0-9 and/or the letters A-F). It is entered into the controller
in two parts (PT 1 and PT 2) consisting of 8 bytes each. Enter the 2 digit value. To enter the digits A-F, first press the
“OFF” key, then press the 0-5 key respectively (i.e. A1 = OFF 0 1 and CB = OFF 2 OFF 1). After the last digit (16
th
digit) has been entered, press the “#” key to store “PT 1” of the encryption key. Press the down arrow key to enter
“PT 2” of the encryption key.
ENCRYPTION KEY PT 2:
DC-67-48-8F-D1-3A-EF-70
After the last digit (16
th
digit) has been entered, press the “#” key to store “PT 2” of the encryption key.
ETHERNET CONNECTIONS
Use a standard network cable to connect the controller to a hub, switch, or router. Use a network crossover cable
when connecting the controller directly to the NIC card on a computer. When connected to a switch or router, port
forwarding must be configured. Port forwarding sets up public services on your network. The Omni LTe controller
listens for all IP/UDP and IP/TCP communications addressed to it on the specified port number. The router will
forward all communications on the specified port to the Omni LTe controller.
