6.3 Network modules upgrade
The upgrade of the network modules is performed using a standard communication line.
The upgrade file is always bound to the specific SN of the device.
For upgrading a network device raise a context menu of the reader module and select
Upgrade device (NML) or Upgrade device (TFFW) according to the upgrade file suffix.
Note: If a device occupies multiple addresses at the communication line and the
upgrade file is a NML file, it is necessary to connect and upload the license to every
address the module occupies.
The procedure of uploading new FW to a device at a communication line is supported
since the network modules FW version 2.73. The NIO 22 module does not support this
function.
When uploading FW to a multi-address module, you must select its lowest address for
the FW upload.
The FW upload procedure can take up to several minutes depending on the module
type.
