Gateway IP address:
Enter the corresponding IP address here if the unit is to establish a connection outside the local network
independently. Otherwise, this field can remain empty (0.0.0.0).
Video/Audio transmission:
If the device is used in front of a firewall, TCP (Port 80) should be selected as the transmission protocol. For
use in a local network, choose UDP.
Warning!
Multicast operation is possible only with the UDP protocol. The TCP protocol does not support multicast
connections.
Ethernet link type:
Adjust here the ethernet link to the network. In most applications Auto is the correct choice. For some routers
and switches it may be necessary to set the Ethernet link to a fixed value. In that case select the appropriate
value:
• 10 MBit/s HD = 10 MBit/s half-duplex
• 10 MBit/s FD = 10 MBit/s full-duplex
• 100 MBit/s HD = 100 MBit/s half-duplex
• 100 MBit/s FD = 100 MBit/s full-duplex
DNS Server IP address:
The use of a DHCP server, which may change the address of the unit depending on IP address availability on
the network, may lead to connection problems when connecting to a unit over the Internet.
Connecting is easier when the device is listed on a DNS server. The device logs in regularly leaving the device
name, device IP address and the current Internet IP address. To connect to a device over the Internet you just
insert the device name together with the URL of the DNS server which then returns the valid Internet IP
address for automatic connection set up.
Note
Assign a unique name to the 7700 Series unit if you want to use this feature.
DNS refresh time:
Enter the amount of time the unit should wait after contacting the DNS server before it repeats the process.
You can enter a value from 30 to 86400 sec (24 hours). Leave this field empty when not using the DNS function.
