An IP address for the EA-1 adapter needs to be obtained from the network administrator; this example uses an IP 
Address 172.16.16.49, Subnet Mask 255.255.255.0 (default), IP Gateway 172.16.16.1 

 

Note:

 In order to connect to the device using a PC, it may be necessary to first set the PC to a static IP address. 

Instructions for doing this are shown in Appendix 2 below. 

 

The following page should be shown on the web browser once a connection is established for the first time: 

 

 

  

Click on “Ethernet Properties” and the following page should be displayed (on the left): 
 

  

>>

  

 

Enter the new IP address, and click on “Save”. The following message will be displayed at the bottom of the
