1.5 Reconfiguring and Resetting Network Settings
In case you are not able to connect to the QVENC4K
™ through the network port(s), we have
provided 2 different mechanisms for resetting the IP addresses and network settings: through
CodecManager
and through the
USB console serial port
. Any one of these 2 methods we
describe in this section will allow you to recover in case the IP address was changed or set to
DHCP and you do not know its current value.
CodecManager:
As previously described in the last section, if you have a Windows PC or a Mac
running a PC emulator, you can download and run the QVidium application, CodecManager
™, to
change or set the IP address for the built-in Ethernet port. You can download CodecManager from
the Support page at
. If you have more than one network adapter on your
PC, you may need to select the proper Network Interface from the pull-down control in the lower
left corner of the CodecManager application. Also, because CodecManager relies on low-level
Ethernet-level multicasts, we recommend having both the QVENC4K and your PC connected
through a switch, and not via a direct Ethernet cable. If you do not see the QVENC4K on
CodecManager, even after clicking on the Discover button, then you should try connecting to the
other LAN port on the QVENC4K. If you still do not see the QVENC4K, then we suggest either
resetting the network interface using the
USB Console Port
method, below, or via the USB serial
port.
USB Console Port:
Alternatively, you can connect a USB cable to the Console USB port to log
into the Linux shell and change the IP address or other settings. To reset the IP settings to their
factory defaults, connect a PC running a terminal emulator, such we Hyperterm or TeraTerm. You
should then see a new COM port on your PC. Set the Baud rate to 1500000 and try connecting the
terminal emulator to the new USB port. The other serial port settings should be set to 8-N-1, no
flow control. Upon power-on, you should see a stream of characters as the system is booting,
ending with the login prompt
. Login as user “qvidium” with the barcode serial number as the
password,then hit
Enter
. From this prompt, type
resetnetwork
followed by hitting the Enter key
(<CR>, carriage return) to reset the network settings to use DHCP. You can also type
ifconfig
eth0
(and <CR>) to see the current IP address.
If you have experience with network monitoring software, such as Wireshark (www.wireshark.org),
please note that upon power-up, the Encoder will emit a gratuitous ARP packet from which you
can determine its IP address by looking for the ARP packets that the QVENC4K generates and
analyzing its contents.
1.6 Ping and Traceroute
Selecting Ping allows you to test network connectivity by sending ping packets to an address or
hostname you specify. However, to use a hostname in place of an IP address, you must have
configured at least one DNS server.
The following figure, Figure 3, shows the Network Ping configuration and output.
