PROFILE DESCRIPTIONS OF THE UTA
120
To meet different application requirements, the UTA120 provides a series of
parameters (or registers) through which it can be configured. When the UTA120
is in the Command Mode or Escape Command Mode, you can use commands to
modify these parameters (or registers) and control the operations of the UTA120.
Whenever you modify the values of the parameters (registers) the system
automatically keeps the new values in the volatile memory. If you do not save
them in a user profile, the changes are temporary and last only until the UTA120
is reset.
The UTA120 supports three types of profiles they contain all the parameters
(registers). Values for these parameters can be saved as user profiles for later
use.
1. Active profile - is the current operating configuration of the UTA120.
Ø
It can be configured using AT Commands.
Ø
The active profile is lost when the UTA120 is powered off.
2. User profile - is the user’s custom-made stored configuration.
Ø
The UTA120 will automatically load a user profile to the active profile
whenever the system is powered down.
Ø
Two user profiles are supported by the UTA120. Use the “ AT&Wn ” command to save
the active profile as user profile n=1 or n=2 and use the “ ATZn ” to load user
profile n=1 or n=2 as the active profile.
Ø
Users must specify which user profile is used for power-up profile by issuing
the command “ AT&Yn ” where n=1 or n=2
