The firm ware info can be seen via the “Setting” menu on the Display Interface screen. By selecting the “Network” tab a list of all the modules on the network will be displayed. Select the old device for removal. The version number is the Firmware.
All new modules supplied from the factory will have the latest firmware.
If the Firmware is incorrect it will need to be matched or updated via the configuration tool. If the user has the configuration tool or is familiar with configuration tool they will be able to update the Czone system them themselves. Otherwise contact your nearest distributor to have the system updated.
