10.2. Upgrade process
10.2.1. Tips for the upgrade process
Cross UTP connection
To avoid packet loss caused by an overloaded network, it is recommended to use cross
UTP connection directly from the upgrading PC to the Lightware device.
Disable other Ethernet devices
The Bootloader software always queries the PC's primary Ethernet adapter (which is
usually the adapter that is connected to the Internet) for available Lightware devices. It is
recommended to disable every other Ethernet device (secondary LAN, Wi-Fi, 3G modem)
for the time of the upgrade. If the Bootloader cannot find the Lightware device because
the device is connected to the secondary Ethernet adapter (cross UTP connection), you
need to disable the primary adapter (Internet). This way the Ethernet adapter which is
connected to the Lightware device will become the primary adapter and the Bootloader
can query it for Lightware devices. If you disable an Ethernet adapter while the
Bootloader is running, you need to restart the Bootloader to be able to query the Ethernet
adapter again.
A second option in this case is that if you know the IP address and port number of the
Lightware device, you may use the Add IP button.
Remove I/O connections
It is recommended to remove all video input and output connections from the Lightware
device. Video sources and display devices may try to communicate with the Lightware
device or send noise through the cable which may interfere with the upgrade process.
Latest Bootloader
Always perform the firmware upgrade with the latest Bootloader software. To get the
latest Bootloader software, contact your local sales representatives or Lightware's
support team at
Finishing the process with older versions of the Bootloader
Bootloader versions that are older than v3.1.8 do not close the connection with the
Lightware device automatically upon finishing the upgrade process. With these versions,
if you remove the UTP cable or restart the Lightware device before you properly exit the
Bootloader, the Lightware device will stay in a so called 'bootload mode' and will not
return to normal operating mode. In such cases connect to the Lightware device with the
Bootloader again and exit from it properly.
Restart the device
After a successful firmware upgrade, the device will restart itself but it is recommended to
power down and up the device after finishing the upgrade.
10.2.2. Firmware upgrade
Step 1. Connect the Lightware device and the computer via Ethernet (hub, switch, router)
If you are connecting via hub, switch or router, then you can either set the Lightware
device to have a fix IP (in which case make sure that there is no IP conflict on the
network) or you can set the Lightware device to DHCP mode (in which case the
Lightware device will acquire an IP address automatically). In this case the network must
have a DHCP server. These settings can be done from the front panel LCD menu or via
the supplied Lightware Device Controller software. If you are connecting directly, via a
cross UTP cable, you need to set up a fix IP and subnet mask on the Lightware device
and the PC.
