General Help guidelines:

If you have trouble connecting the CXN v2 to your network, these steps may help to resolve the problem:

• Confirm that a connected computer can access the Internet (i.e. can browse the web) using the same network.

• Check that a DHCP server is available, or that you have configured a static IP address on the CXN v2. You can configure a static IP address on the CXN v2 using the menu item ‘Settings -> Network Config -> Edit Config’, and then select ‘No’ for ‘Auto (DHCP)’. DHCP is however the recommended method.

• Check that your network’s firewall is not blocking any outgoing ports. As a minimum, the radio needs access to UDP and TCP ports 80, 5­54, 1755, 5000, 6000 and 7070.

• Check your access point does not restrict connections to a particular MAC addresses. You can view the radio’s MAC address using the menu item ‘Settings -> Network Config -> View Config -> MAC address’.

• If you have an encrypted Wi-Fi network, check that you have entered the correct key or passphrase into the CXN v2. Remember that text-format keys are case sensitive. If, when attempting to connect to an encrypted network, your CXN v2 displays: ‘Wireless error’ followed by a 5-digit number, then please ensure that you enter the correct passphrase for the network. If the problem persists, then you may need to consult your network configuration.

If your CXN v2 can connect to the network successfully, but is unable to play particular Stream Magic stations, it may be due to one of the following causes:

• The station is not broadcasting at this time of the day (remember it may be located in a different time zone).

• The station has reached the maximum allowed number of simultaneous listeners.

• The station is not broadcasting anymore.

• The link in our database is simply out of date.

• The Internet connection between the server (often located in a different country) and you is slow.

• Try using a computer to play back the stream via the broadcaster’s web site.
If you have problems with UPnP playback always check the following:

• Ensure your chosen UPnP server software is capable of serving the file type you are trying to access. Some servers do not serve FLAC for instance.

• The CXN v2 can only play non DRM files. Files that have DRM controls cannot be played by the CXN v2. Some servers may be able to authorise and de-crypt Microsoft Playsforsure before then serving the content to the CXN v2 but this operation is not guaranteed as it is purely a function of the server.

• If attempting to play 24-bit WAV or FLAC content note a wired Ethernet connection is normally required for reliable operation due to bandwidth considerations.

• Check the CXN v2 is capable of playing back the file type you are trying to access. WMA, AAC, MP3, Vorbis, FLAC and WAV can currently be played. The CXN v2 does not support ALAC, WMA Pro, WMA lossless, RAW, AU or other file types not mentioned.

If you have problems with USB Media playback  always check the following:

• Check the CXN v2 is capable of playing back the file type you are trying to access. WMA, AAC, MP3, Vorbis, FLAC and WAV can currently be played.

• The CXN v2 does not support ALAC, WMA Pro, WMA lossless, RAW, AU or other file types not mentioned.

• For USB Media the CXN v2 can only play non DRM files. Files that have DRM controls cannot be played. 

• Check that your device does not require more than 1A if it is powered from the USB socket itself.

• Check your device is formatted in FAT32/NTFS format.

• The way you organise your USB media affects the size of internal database the CXN v2 needs to build dynamically as you browse content. Good practice is to create folders for Artists within which you should have a sub folders for each Album which then containing the tracks for that Album. Libraries with thousands of tracks in one folder will progressively slow down the CXN v2s media browsing.
