  • Send File: sends a file to the device, displays the transfer progress bar at the bottom of the window, correct transfer is confirmed with a message "Transfer complete";
  • Reload Firmware: uploads a firmware file–this operation must be preceded by a transfer of an adequate firmware files to the device. Upon update, the device shall be rebooted;
  • Device Reboot: reboots the device;

  • Modbus TCP: using the Ethernet port;
  • Modbus RTU: using the RS485 port–this type of communication requires the device to be in the bootloader mode.
