Upgrading
The internal software (firmware) of the AV204T and AV208T transmitters can be
upgraded in order to take advantage of a continual process of improvement and
innovation. The supplied serial cable is required to connect the AV204T/AV208T
module to the serial port of a suitable system.
Note: It is not possible to alter the firmware within the AV200T transmitter
or the AV200R/AV201R receivers. The operation of these modules are not
dependent on the revision of the AV204T/AV208T transmitters.
You can discover the current version of your module using the upgrade
application.
To upgrade AdderLink AV204T and AV208T transmitters
1 Download the latest AV204T/AV208T firmware upgrade file from the
Adder website: www.adder.com. The upgrade files are compressed using
pkzip format which you will need to decompress them. If you do not have
pkzip, go to www.pkware.com to download the latest version. Place
the decompressed upgrade files onto the Windows system that will be
connected (via a vacant serial port) to the Adder module.
2 Remove power from the module.
3 Connect the supplied serial cable between the port labelled IN on the
module and a vacant serial port on the system containing the upgrade files.
4 On the side of the module, click mini switch 1 to its ON position.
5 Re-apply power to the module and switch on the system to be used for the
upgrade.
6 Locate and run the application ‘KVMUploader’ to display this window:
7 Click the Browse... button and locate the TXT file that accompanied the
upgrade utility. Highlight the TXT file and click the Open button.
8 Click the Advanced... button and in the subsequent dialog, ensure that the
Serial Port entry matches the port to which the upgrade cable is attached.
Also select the Program and verify option. Click the OK button.
10 Click the
Upload Now button to begin transferring the upgrade data from
the system to the module. The progress of the upload is shown in the status
bar (indicating the advancement of the current task) and the progress bar
(indicating the progress of the upload as a whole).
During the upload, all buttons become disabled except for the Abort
button. The upload can take as long as fifteen minutes. Should you need to
abandon the upload at any stage, click the Abort button.
Following the upload, a verification will be carried out and the results
displayed within the upgrade application window.
11 When complete, switch off the module, disconnect the serial cable, return
mini switch 1 to its OFF position and resume operation of the AdderLink
module in the usual manner.
9 Click the Query Unit button to check the name and version of the current
firmware - the application will interrogate the module via the serial cable.
Once the version information is displayed, check that the Intended Target
Units field matches the Unit Connected field and the New Firmware Version
field exceeds that of the Current Firmware Version.
