SERVICING and TROUBLE SHOOTING (cont)
Symptom: Some of my RHAON features are not working even though they worked previously. For example, when I try to
change Presets the new Preset won't load and I can change my EQ settings but can't save them to the loudspeaker(s).
1. This indicates your CobraNet components are not functioning properly and communications between your computer and
the loudspeakers on the network have been disrupted, a problem caused by your computer having gone into Sleep mode o
by some other Windows event. To correct, close RHAON (and, if running, CobraNet Discovery) and bring up the Windows \
Task Manager (Ctrl-Alt-Delete). Under the "Processes" tab , look for 'PACNDISCO.EXE' and 'PASSBRIDGE.EXE' (Windows
may alter the names and add '~1'). Select them and click "End Process". Proceed to re-open RHAON and/or CobraNet
Discovery.
An alternate method of correcting the problem is to Restart the computer. To prevent this from reoccurring set your laptop's
Hibernation / Sleep settings to "Never".
Note that this CobraNet malfunction does not affect normal operation and your system will continue to operate normally until
you try to change some of the settings.
SWITCH RELATED ISSUES
Symptom: I placed my RHAON devices on the same network as other devices (venue PCs, lighting, etc.) and now neither
RHAON nor the other devices are acting abnormally.
1. We recommend that your RHAON network be placed on a network separate to that of anything else. If it is absolutely
necessary to have them running through the same switch, it is recommended to use a managed switch and set up separate
Virtual Local Area Networks (VLANs), grouping the ports you wish to use for RHAON in one VLAN and the ports for other
devices in another.
Symptom: I have set up my VLANs but now I cannot connect to / scan for the RHAON loudspeakers on my network.
1. Verify that the physical ports both your RHAON loudspeakers and your computer are connected to are all on the same
VLAN.
2. Verify that SNMP traffic (UDP ports 161 and 162) and CobraNet traffic (Ethernet protocol identifier 0x8819) are allowed on
your VLAN. Consult your switch documentation for how to configure VLANs.
Symptom: I have to wait 10-20s for my device to be "connected" and traffic to begin when connecting my loudspeaker to the
switch.
1. Your switch may have Spanning Tree Protocol (STP) turned on. STP prevents accidental looping in your network topology,
but unfortunately needs to run an analysis on any new connection before it is deemed OK to be "on". If you want to avoid the
delay and don't need any services STP provides, turn off STP on your switch. Consult your switch documentation for instruct-
ions.
NOTIFICATION E-MAIL RELATED ISSUES.
1. Be aware that a second network interface connected to a separate network is required for Email notifications or using
Remote Desktop-type software to control the RHAON computer..
You will need to contact the network administrator at the installation for details on connecting to their Simple Mail Transport
Protocol (SMTP) server, also known simply as 'the outgoing email server'.
Symptom: While attempting to send emails I receive the following Error Message "The specified string is not in the form
required for an e-mail address."
1. Be aware that what you enter in the "Name of Installation:" field is used as part of a spoofed "From:" field in the notification
email. Use of non US-ASCII characters in an email address is invalid. For example, use of Greek letters, symbols not on a US
keyboard, or the '@' symbol are not allowed. For more information, please visit: http://en.wikipedia.org/wiki /e-mail_address.
