Send the firmware file with the file transfer protocol 1k-XMODEM
using the terminal program.
If you do not send a firmware file, the INSYS Pocket ISDN will
terminate the procedure after approx. 60 seconds.
The INSYS Pocket ISDN indicates the successful upload of the
firmware with e.g.:
Loading procedure ended successfully.
If the firmware update fails, the INSYS Pocket ISDN responds to all AT
commands (like e.g.
at**ver
) with the reply:
ERROR: BOOT LOADER ACTIVE.
Configure the baud rate to
115.200 bps in any case. If you only enter
AT
,
OK
will be returned.
Repeat the firmware update in this case. Observe that your terminal
program really uses the XMODEM-1K protocol.
If you didn't receive the previous message for a successful upload, the
upload has most probably failed. Try to reset the INSYS Pocket ISDN
and to repeat the process from step 4. If this fails and the INSYS
Pocket ISDN does no longer react to AT commands, please contact
the INSYS MICROELECTRONICS support department.
The INSYS Pocket ISDN will reset itself and is ready for operation.
