The "OTT Z400 Application Software" is stored on the removable storage device (comparable to a USB-Memory-Stick) of the counter OTT Z400; file: "Z400.exe". To make an update this file has to be exchanged. How to install the Update: Download the new version of the file "Z400.exe" to your PC. Remove the yellow rubber cover on the back of the OTT Z400. Connect the USB-connecting cable to the OTT Z400 (see fig.5 in the OTT Z400 operating instructions). Connect the USB-connecting cable to a USB-interface of your PC. Start the Z400: press the "Start/Stop" key -> the PC recognizes the OTT Z400 as external storage device (when the unit is connected for the first time, the PC installs the USB interface driver first). Copy the new version of the "Z400.exe" file onto the storage device. This replaces the old version. Disconnect the USB device from the PC by using the function "Safely Remove Hardware" of the PC. Remove the USB connecting cable -> the OTT Z400 automatically switches off. Put the yellow rubber cover back into place. Notes The update is possible from any previous version. On the removable storage device of the counter there is an online-help file in various languages (Z400_xx.chm) and two configuration files ("Configuration.ini" and "Z400-Configuration.txt"). These configuration files may not be deleted, neither may the content be changed! Otherwise the counter will become unusable! More information on the use of the counter is provided in the operating instructions of the OTT Z400.
