Connecting to the Controller via Ethernet Communications 
 
WARNING 
Connecting to the Controller via Ethernet Communications requires that you change your PC’s 
IP settings. If you have never done this before, then it is strongly recommended that you 
consult with your Information Technologies (IT) representative before proceeding. 
 
First, write down the current IP Address, Subnet Mask and Default Gateway settings for 
your PC. Put these someplace that you can find them later. 
Connecting to the Ethernet Port in the Controller requires that you have either an 
Ethernet crossover cable or a MDI-compliant Switch or Hub available with a straight-
through cable. The crossover cable can be used to directly connect your PC to the 
Controller while the Switch or Hub can be used to connect your PC and Controller to the 
Hub or Switch via straight-through cables. 
Once you have made an Ethernet connection between your PC and the controller, then 
change the Local Area Network (LAN) settings on your PC to be as follows: 
 
IP Address:             10.0.0.3 
Subnet Mask:     255.255.255.0 
Default Gateway:    10.0.0.1
