CONFIGURING ETHERNET COMMUNICATION
Summary
There are three basic LCI3 Ethernet configuration types which may be required for Ethernet communication. These
configurations types are Ethernet with Crossover cable, Intranet, and Internet.
This section provides quick start instruction for setting up each configuration type.
• Configure the LCI3 to communicate to a PC using a cross-over cable
• Configure the LCI3 to communicate to PCs on an Intranet.
• Configure the LCI3 to communicate to PCs on the Internet.
NOTE: The LCI3 is capable of communicating to other LCI3s and may also send e-mail via the ethernet.
Those applications are addressed in another section of this document. In addition, these procedures are
intended for individuals who are experienced with PC's and routers.
Using a cross-over cable from a PC
The following procedure may be used to allow a PC to communicate to an LCI3 using a cross over cable. In this case,
the PC and LCI3 must both reside on the same network and therefore must have the same subnet address. This exam-
ple uses Windows 7 as the operating system. Please refer to the PC user manual or IT technician if setting up with a
different operating system.
Procedure
1.Determine the PC’s IP address and subnet address; See also Figure 1 for Windows appearance.
• Right click on the "Network" icon on the PC's desktop. Choose Properties.
• Choose Change Adaptor Settings.
• Right click on Local Area Connection and choose Properties.
• Click on Internet Protocol Version 4 (TCP/IPv4) and select Properties.

Configuring Intranet Communications
The following procedure may be used to allow the LCI3 to communicate to all PC's on the same network ( i.e. in the
same building with no external communications). In this case, the PC's and LCI3 must all reside on the same network
and therefore must have the same subnet address. This example uses Windows 7 as the operating system. Please
refer to the PC user manual or IT technician if setting up with a different operating system.
Procedure
1.Determine the PC’s IP address and subnet address; See also Figure 1 for Window appearance.
• Right-click on the Network icon on the PC's desktop. Choose Properties.
• Select Change Adaptor Settings.
• Right-click on Local Area Connection and choose Properties.
• Click on Internet Protocol Version 4 (TCP/IPv4) and select Properties.
NOTE 1: Please note the IP and Subnet address
NOTE 2: If there is an IT department the information can be obtained from them and they will also provide
you with an IP address that can be used for the LCI3.
NOTE 3: All devices on the network must have a unique IP address.
2.Now that a PC’s address and subnet are known or have been provided by the IT department, the LCI3 can be
configured by doing the following.
• Sign-on to the LCI3
• Select ‘Utilities’ from the Home screen
• Select ‘Network Setup’ from the Utilities screen
• Select ‘Ethernet Settings’ from the Network Setup screen
• Set ‘Enable DHCP’ to NO
• Enter an IP address for the LCI3: This address should be the same as a PC with the last number being differ-
ent. Example:
PC 10.0.1.59 --> make the LCI3 10.0.1.60. The address may also be obtained from the IT department.
NOTE: All devices on the network must have a unique IP address.
• Enter the proper subnet as found on the PC or as provided from the IT department
• Depress ‘Save’
3.To establish communication perform the following.
From a PC on the network, launch Internet Explorer or your preferred web browser
Using the IP address from step 2, type the following in the address line: http://10.0.1.60/lci3/firstpage
