To download the firmware via the console interface, the L-Gate must be connected to the
RS-232 port of a PC via its console interface as described in Section 10.2.1. You will need
the LOYTEC serial upgrade tool (LSU Tool), which can be downloaded from our

start the LSU Tool and load the firmware image referenced in the dlc file. Please note
