2. If “Network Inteface” is not grayed out, select the network having the codec
3. Click “Discover”to probe for QVidium codecs
4. If you do not see the codec, then:
1. Try plugging the Ethernet connector into the other LAN port on the codec and click Discover again.
2. Check that the green link LED light comes on when you plug in the Ethernet cable. If not, try using another Ethernet cable or a cross-over Ethernet cable.
3. If you still do not see the codec IP address, then try resetting the network parameters to the factory defaults.
4. If you still do not see the IP address, contact QVidium Technical Support.
5. If desired, you can change the IP address of a codec by highlighting the codec and clicking “Edit”
6. Make certain that the IP address you are using is on the same subnet as the PC running your web browser. (See next section for setting the network subnet.)
1. Make the subnet mask the same on the codec as on the PC/MAC.
2. If the subnet mask is 255.255.255.0, then make the first 3 octets of the IP address on the codec the same as on the PC/MAC.
1. Set the IP address of the QVidium Encoder/Decoder and/or the PC/MAC so that they are on the same subnet and make certain that they are not set to the same IP address.
2. If you still cannot connect, e-mail QVidium Tech Support.
1. Disable all other network adapters except the one Ethernet adapter connecting to the QVidium device.
2. Connect the PC/MAC to a simple Ethernet switch and the QVidium device also to that same switch. Do not connect directly from the QVidium device to the PC/MAC.
3. Assign a static IP address to the PC/MAC and disconnect from the Internet and from any Internet routers.
1. Please remember that to send video over the Internet, you cannot use the local 192.168.XXX.YYY address. Any IP address beginning with 192 is a private address, and cannot be directly used over the public Internet. Most Internet connections are through a Firewall. You must set up Port Forwarding, or Network Address Translation (NAT) so that when you send the video stream from your encoder, you can use the public IP address of the firewall, and have the firewall forward those packets to the decoder. Please see your network administrator for further help in setting up your firewall to enable port forwarding to the decoder.
2. If you are using ARQ error correction, we suggest that you set the ARQ port and the video UDP port to the same value (if you are not using server mode) so that you can avoid setting up port forwarding for the ARQ retransmission request packets on the encoder-side firewall.
1. Check that there are no typos in the address, eg. no commas in place of periods.
2. If the decoder is behind a firewall, then the destination address entered in the encoder profile should be that of the decoders Public IP address. You can use a web browser on the same LAN as the decoder and go to http://www.ipchicken.com or https://whatsmyip.com/ to find the public IP address.
1. Check that you can ping over the Internet from the encoder and the decoder. Click on Network/Ping from the encoder's and decoder's web interfaces and try to ping the Google address: 18.104.22.168 from both the encoder and decoder.
2. If there are no ping replies, then please check that both the gateway and netmask are correctly set under Network/LAN1 (or LAN2 if appropriate).
3. If using both LAN1 and LAN2 (eg, QVPRO/QVSD or accessible on QVENC and QVSD with Apple Ethernet/USB Dongle), make certain that you only set a gateway for one of the two LAN/Ethernet interfaces, and leave the Gateway field blank on the other LAN interface. (Multiple default gateways will cause unpredictable behavior with the operating system.)
