Upgrading the Firmware 152
Upgrading the Firmware
From time to time, SerVision releases new firmware versions for the Video Gateway. This section explains how to
obtain and install new Video Gateway firmware. New firmware can be installed on-site or remotely. It is
recommended to install it on-site whenever possible. If your distributor has a TVG Upload Server to which you
can connect, you can upgrade the firmware using the configuration utility. Otherwise, you must download the
firmware from the SerVision website and use the TVG Download Utility to download it to the Video Gateway .
NOTE: Upgrading the firmware does not change any of the unit’s settings.
CAUTION: If the download process is interrupted in any way before it is completed, or if an incompatible
firmware version is loaded, it may be impossible to connect to the unit in the normal way again.
Make sure that you know in advance that you are loading the right firmware, and DO NOT
INTERRUPT THE DOWNLOAD PROCESS once it is started.
If it nevertheless becomes impossible to connect to the unit after an attempt to upgrade the firmware,
the Catch Boot operation can be used to reconnect to the unit and download the firmware to it
again. See Catch Boot Operation, page 156.
SerVision routers have their own firmware, and this firmware may require upgrading from time to time. These
routers are built into MVG and UVG units. For information about upgrading the router firmware of these models,
see Upgrading Router Firmware, page 160.
Upgrading Firmware via a TVG Upload Server
If your distributor has a TVG Upload Server to which you can connect, you can upgrade the firmware using the
configuration utility. Before you begin, ask your distributor for the IP address or hostname of the server and its port.
To upgrade the Video Gateway firmware from a TVG Upload Server:
1. In the Main Menu, click Diagnostics, and then click Upgrade Software. The System Upgrade screen
opens:
