puts with no processing or delay. This design acts as a failsafe, even in the event of a
power failure.
But in an IP based audio world, there is no equivalent. Relays can’t route IP packets. If
the power has failed, there’s no way to route them at all.
Therefore, pressing
BYPASS
on PDM-Axia units has the following effect:
•
Any existing buffer gets dumped.
BUILD
,
EXIT
and other controls become in-
active.
•
Inbound packets get sent out, bypassing any PDM-specific functions. There is,
however, a tiny delay while the packets pass through PDM’s computer.
You may find it useful to set up Pathfinder software so that PDM’s Bypass button actu-
ally changes the IP routing, and removes PDM from your Livewire air chain.
Livewire Troubleshooting
During startup, PDM’s LCD will look like this for a moment:
Waiting for
Audio stream
This means that PDM is logging on to the Livewire network.
CNFG
Use
to access the Configuration menu.
The screen will go away after PDM has successfully logged onto the Livewire network.
Once it is gone, PDM’s LED level meter should switch from yellow to green. You should
see the meter bounce when IP audio is being properly sent to PDM.
If the
Audio
stream
message remains up for several minutes after you start PDM,
check the following:
•
Does the
INFO
screen show a valid IP address?
•
Remember, Axia uses Static IP addresses assigned by the user, not DHCP
addresses automatically provided by the router. If your PDM is set for
DHCP
,
follow the instructions on page 57.
•
If the address is valid, can you Ping this address from another machine on the same
network segment?
•
If not, check network connections, cables, and switches.
•
Are you using the correct Network Mask? Some Livewire networks may be
configured on a class B Subnet. Try changing the Network Mask setting to
255.255.0.0
•
Does your Pathfinder router software know PDM is on the network? You may need
to add PDM as a listed device within Pathfinder.
