CodecManager
& System Reset
4.1 CodecManager
QVidium supplies an application we call
CodecManager
™
as a free download for its customers
under the
Downloads
section of the QVidium web site at
CodecManager
will detect any QVidium® Video Codecs, Decoders, and Decoders connected
through Layer-2 switches over the local-area network. At launch,
CodecManager
sends a Layer-2
MAC broadcast to which the QVidium products respond with their MAC address, IP Address, and
name. From this application, you can double-click on a QVidium product to launch a browser
window to that device. In addition, CodecManager makes it simple to change the IP Address,
launch a Telnet window, or edit other settings of any QVidium product it detects directly from the
CodecManager
application, even if several devices are mis-configured with the same IP address.
You can also instantly stop all decoders by the simple click of a button.
We encourage you to download and use the
CodecManager
application to manage your QVidium
products. You can download a PC version of CodecManager for Windows 10 PC, and a Java
version, provided that you install Java on your computer.
Note: CodesManager
may not work when the Ethernet cable is connected directly between the
PC and the QVidium product, as it requires connection through a switch to multicast the
identification packets. With the Windows PC version, you may need to disable network adapters
other than the Ethernet network adapter, such as any WiFi adapters.
4.2 Resetting the QVDEC4K
If you wish to reset the network settings or the password on your QVDECrK decoder (or a
QVDEC4K decoder), you can use a USB flash drive and follow the relevant procedure from the
QVidium web site at:
. These reset procedures involve downloading and
saving a file called, "autorun," to your USB flash drive and inserting it into the USB-A port on the
back of the QVDEC4K (or QVDEC4K).
4.3 Command-Line Interface
4.3.1
Mounting and Un-mounting an External Storage Device
When you connect a NTFS or FAT formatted external storage device to the USB interface, the
embedded Linux Operating System will automatically mount the file system. (If you wish to connect
a Linux formatted Filesystem, such as ext2 or ext3, you will have to manually mount the file
system.) The initial mount point is
/media/sda1
. From the command-
line interface, first type “
cd
/media/sda1
” then use “
ls
” for a listing of the files on the storage device.
However, if you wish to remove a mounted storage device, you must first unmount it. To unmount
the disk or storage device, you must first stop any programs that are accessing the device, then
you must
cd
away from the mounted
directory, such as “
cd /
”. You can then issue the unmount
command:
“
umount /media/sda1
”. After this command successfully completes, you can safely
remove the external storage device and, if desired, insert another storage device. As long as you
first unmount the old storage device, the next storage device will be mounted as
/media/sda1
. If
you do not unmount the storage device, or mount a second storage device, the second device will
mount at location
/media/sdb1
. Currently, there us a limit of only 2 different mount points,
sda1
and
sdb1
. Additional partitions on a given storage device will auto-mount as
/media/sdaX
or
/media/sdbY
, where X and Y are partition numbers starting with 2, and incrementing up to the
number of partitions on that storage device.
