There is nothing displayed on the monitor though power is supplied to the module.
1) Check if the power is supplied properly.
2) Check the true HD / VGA cable connection with the module. Remove all the cable connections,
except for the monitor cable, and then apply power to the module again.
3) In case that the display screen is stopped at the logo screen, please contact Digital Watchdog’s
technical support for additional information.
Is it necessary to open the port when using DDNS?
Yes, it is. DDNS is the function that lets remote connections acknowledge the changed address of
the module (dynamic IP provided by ISP) or to allow connection to the module by the domain
(domain.dynlink.net) without memorizing IP.
Remote software connection to the module works fine but WEB connection doesn’t work.
1) Some ISP blocks port number 80. Please try again after changing the WEB port.
(8080 is recommended.)
2) Check whether port 80 is opened or not.
Image is not shown after login at WEB monitoring
TCP Base port should be opened. The default of the TCP base port is 9010.
The image on the remote software has suddenly disappeared after displaying it for a short
time.
1) Some ISP restricts upload data/traffic volume. Please contact your ISP.
2) Upload traffic restriction can be easily checked with the following steps.
> Turn off the power of your Modem & Router.
> After 60seconds, turn on the power of your Modem first and then Router.
> After reconnection, if it is disconnected again after a short time (in a similar period later),
it means that the ISP restricts upload traffic.
Backup or firmware upgrade through USB memory stick cannot be made though it is detected
by the module.
1) USB memory stick should be formatted by FAT or FAT 32.
2) It is not allowed to use a partitioned or password-encoded USB memory.
Time sync through the NTP server doesn’t work.
The NTP server requires a DNS server address. Check if the DNS server address is correct at the
Network setup page.
E-mail transmission doesn’t work in using E-mail to notify function.
1) E-mail notify function works based on SMTP service.
2) Check if the sending mail address is correct and if the mail server supports SMTP service.
3) If you are using an SMTP service that is based on TLS authentication (including SSL) such as
Gmail and yahoo mail, enable the Use SSL Authentication at the Notification setup page.
4) SMTP service is provided based on DNS. Check if the DNS server address is correct at the
Network setup page.
