(Optional) Innovator CX Series Web Ethernet Interface Kit (1313100) 

 
The Innovator CXB transmitter is available with two optional Ethernet interface 
packages.  Axcera part number (1313100) is the Axcera part number for an Ethernet 
Interface kit that serves HTML web pages.  Axcera part number (1313079) is an 
Ethernet Interface kit that provides an SNMP interface to transmitter parameters and 
also serves HTML web pages.  Either option may be added to the Innovator CXB 
transmitter if it was not originally installed at the factory.  

NOTE:

 Internet Explorer 

Version 7 or higher is required.

Once a connection has been established, the web interface can be launched by entering 
the IP address of the Innovator CXB Ethernet Controller as a URL in the browser of the 
remote computer.  A login screen will be displayed prompting for a user name and 
password, 

which are case sensitive

.   

 
The controller has two levels of user access: Administrative and Read Only.  
Administrators have full access to transmitter controls and controller configuration.  
Read Only users can view all transmitter parameters and the event log entries but they 
can not change the transmitter's state, clear faults, clear the event log or configure the 
Ethernet parameters. 
 
Five unique login accounts are available.  The factory default user name and password 
for account number one are: 

 
 
 

User Name

The user name and password of account number one may be reset to factory default 
values through a setup screen of the transmitter. 

 

Indicates SNMP or GUI with package software version and 
number of users currently on-line.
