SerVision Embedded Video Gateway System Guide

Upgrading the Firmware 157

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

Description

Flashes orange once when power is restored and

then remains a solid green

Catch Boot can and should be performed.

Flashes orange/green every second

Catch Boot is not necessary, because the unit has a

valid software version.

Remains solid green and does not flash orange

Catch Boot cannot be performed.

Alternates between flashing quickly for a half

second and remaining solid for a half second

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 Video Gateway 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.
