10.6 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 requies
conventional P25 data infrastructure. It is not supported in P25 Trunking. Firmware
updates cannot be made usisng this feature. Firmware version 4.12.x (x-platform) or 6.6.x
(ES) or later is required to use this feature.
10.6.1 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 portable subscriber units, the user should press the <F2> button to indicate an
affirmative answer or the <F1> button to indicate a negative answer.
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
action and any buttons/menu items must be programmed in PC Configure prior to
beginning an OTAP procedure if an action other than the default “Prompt” is desired.
The radio must also be registered with the data router for an OTAP procedure to take
place.
- If the radio has undergone a successful download, by selecting the menu item or
pressing the button, the radio displays the message “Activating” followed by a reset
of the radio.
