kClient HTML Help (UPGRADE)

General information

The KKO4 card includes 4 cooperating processors :

Main processor (ETH)
Trunk and ISDN processor (PCM)
Voice detectors processor (VOX)
Announcement processor (SND)

Each processor has bootloader software besides normal firmware. So it makespossible to load firmware from proper HEX file. This process is executed via LAN and Xport device - so, it doesn't require extra hardware or software. The user is able to download the newest firmware and reload it to given processor himself.
Downloading process for PCM,SND and VOX processors is carried out indirectly via ETH processor, the ETH processor can be upgraded directly. All upgrades for PCM,SND and VOX run in online mode only from kClient software. The ETH processor can be upgraded in online mode too, however in fact it is automatically logged out before loading new firmware.

Beginning from 4.21 version there is running compatibility mechanism procedure. All processors on the card and kClient software must be loaded with the same number of version (e.g. 4.21). In order to upgrade all system to newer version it is necessary:

Required steps:

1. Install newer version of kClient software.
2. Login in Administrator or Supervisor level.
3. Uncompatibility warning will appear but Upgrade option only will be available.
4. Load ETH processor first
5. Next, after ten-odd seconds wait, login again
6. Finally, load the rest of processors : PCM, VOX and SND.

Additional notices for upgrading processors on the KKO:

Before upgrading close all conferences, switch off PCM cables.
LAN cable must be connected.
Only one user must be logged on Supervisor level.
Download (from : www.aerjot.pl) proper HEX file for processor to upgrade you want. The best destination folder is: AeRJoT\kClient\Upgrade.
Use Show status button in order to read current signature. Number of version is important information (e.g. 4.21). Compilation date and time is only additional information.
Compare both versions. Load it only if downloaded version is newer.
Use Upgrade button in order to open proper HEX file for given processor.
If the file is uncorrect, the user will be warned and procedure will be stopped.
After selection and confirmation the file, estimation loading time will be displayed.
After confirmation downloading process will start; don't plugg off LAN cable, don't plugg off the KKO card from magazine, don't switch off the power source!
Progress bar at the bottom of the window informs about upgrading progression.
After loading, new signature (date and version number) will display in given processor's panel :
After upgrade, PCM,SND and VOX processors should return to normal work.
In case of troubles (no progress of loading) it is possible to close Upgrade window, logg off and reset the card by plugg it off from magazine. After this, next upgrade is possible. Note! After error in upgrade procedure you have to reset the KKO card!
An exception is main ETH processor. If an error in this processor occures and it stayes in bootloader, it will not be possible to log in again. In this case open kClient in Supervisor level, don't log in, open Upgrade window and try upgrade again (this option should be active in offline mode).
After proper loading ETH processor, close kClient software, restart the KKO card, wait 15 seconds and open kClient again and log on again.
