This allows a 7700 Series unit unit to be serviced and updated remotely without intervention by a technician to
make on-site changes to the unit installation.
The latest firmware can be obtained from DVTel Technical Support or downloaded from the Internet at our Web
site www.dvtel.com.
Warning!
Before starting the firmware upload, make sure you have selected the correct upload file! Uploading the
wrong file can result in the unit no longer being addressable, requiring it to be replaced. Never interrupt
the installation of the firmware. Interruption will damage the Flash EPROM. This may also render the unit
inoperable and make replacement necessary.
– First, save the update file to the hard disk.
– Enter the full path for the update file in the field or click Browse... to locate and select the file.
– Click Upload to begin transmission to the unit. Transmission progress can be monitored from the status
messages and the progress bar.
After the upload is completed successfully, the unit will restart automatically.
If the operating status LED flashes red and green alternately, the upload has failed and must be done again.
This requires that you work from a special page:
– Enter the IP address of the unit in the browser and append /main.htm (e.g. 192.168.0.12/main.htm).
– Repeat the upload.
Configuration download:
You can save the unit's configuration data to a PC.
– Click Download. A dialog box will appear.
– Follow the instructions in the dialog box to save the current settings.
Configuration upload:
You can upload configuration data that you previously saved to a PC, to the unit.
– Enter the full path of the file to upload or click Browse... to select the desired file.
– Make sure that the file to load is of the same type as the unit you want to reconfigure.
– Click Upload to start transmitting the file to the unit.
This message will appear: Configuration upload finished. State: Configuration upload ok (the system
must be rebooted), and the countdown for reconnection will be displayed.
– Restart the unit.
The next time the software update page is opened, the message Configuration upload ok should appear,
confirming the successful completion of the upload. If the message Configuration upload failed is displayed,
the file did not upload correctly. Repeat the upload in this case, possibly with a different file.
Function test
Once installation and configuration is completed, make sure that::
• the 7700 Series unit can be contacted remotely and transmits all required data
• the unit responds as configured to alarm events
• peripheral devices respond properly to control signals.
