5.15 Over the Air Programming
OTAP is an “Over the Air” programming feature for the subscriber parameter (code plug)
files. Using the OTAP feature, parameter files can be updated and changed in the field,
eliminating the need to take the radio out of service to perform the updates. OTAP
requires conventional P25 data infrastructure. It is not supported in P25 Trunking.
Firmware updates cannot be made using this feature. Firmware version 6.6.x (ES) or later
is required to use this feature.
5.15.1 Radio Set Up
The current profile in the radio controls how an OTAP download is handled. How this is
set in PC Configure determines the possible actions the radio should take: “Prompt”,
“Activate”, and “Off-line”.
Prompt
- the radio displays the message “ACTIVATE?” after a successful OTAP download,
prompting the radio user to respond.
- On mobile subscriber units, the user should press the Select button to indicate an
affirmative answer or the <F6> button to indicate a negative answer. The radio user
has 30 seconds to answer. An affirmative answer stores the parameters in the
EEPROM and resets the radio; a negative answer or no answer results in the
parameters remaining in the Flash memory for activation at a later time, but also
resets the radio.
Activate
- the new parameters are automatically written to the EEPROM upon a successful
download. The user sees a display of “ACTIVATING” followed by a reset of the
radio.
Off-line
- the parameters are stored in Flash memory until activated with PC Configure or by
the radio user. The activation method for the radio requires having either a menu item
or a button assigned to the “Activate OTAP” function. The download completion
