After completing the serial port changes (pressing the enter key will be required to complete the 
action) the user will be prompted for a user name and password. The default user name for the U7C 
unit is 

“u7band”

. The default user name is 

“l7band”

 for the L7 unit. The password is 

“csi1234”

.  

After entering the password and pressing return the  TMI main menu will appear. Note: by default the 
Set Parameters option is disabled. To re-enable the user will press 1 and will be prompted for a user 
name and password.   The default user name is 

csi

 and the password is 

csi1234.

The actions displayed

Pressing “1” will 
continue to expand 
this session screen 
and allow the following 
parameters to be set.
