When this happens, you can usually reinstall the firmware using the Catch Boot operation. This option uses the
unit’s built-in boot loader for downloading, and does not need the firmware in order to function.
NOTE:
The Catch Boot operation uses an RS232 cable for download, and is much slower than LAN download.
To see whether it is possible – or necessary – to reinstall firmware using Catch Boot:
• Unplug the unit and then plug it back in. The Power LED indicates whether Catch Boot is necessary and
possible, as follows:
LED Behavior
Flashes orange once when power is restored and
then remains a solid green
Flashes orange/green every second
Remains solid green and does not flash orange
Alternates between flashing quickly for a half
second and remaining solid for a half second
Description
Catch Boot can and should be performed.
Catch Boot is not necessary, because the unit has a
valid software version.
Catch Boot cannot be performed.
There is a major error in the system. Contact technical
support or your vendor. Do not perform Catch Boot.
To reinstall firmware using the Catch Boot operation:
1. Connect the TVG to your computer with an RS232 connection cable.
Note: If you do not have an RS232 cable, please consult your vendor.
Note: If a PTZ controller is connected to the RS232 port, disconnect it first.
Note: You must have an RS232 connector on your PC in order to perform the Catch Boot operation. If one
does not exist, it is possible to purchase a USB-to-serial adaptor, and connect the RS232 cable through it. Such
adaptors are available in most computer stores.
2. Run the TVG_download.exe utility with the –t parameter.
To add the –t parameter, create a shortcut to TVG_download.exe, open its Properties and in the Target
field add –t after the file name.
