MODEL 348
INTERCOM STATION
assign a unique IP address in the IPv4 range
of 169.254.0.1 to 169.254.255.254. In this way,
multiple Dante-enabled devices can be con-
nected together and automatically function,
whether or not a DHCP server is active on the
LAN. Even two Dante-enabled devices that are
directly interconnected using an RJ45 patch
cord should correctly acquire IP addresses and
be able to communicate with each other.
As previously discussed in this guide, the Mod-
el 348’s IP address(es) and related network
parameters can be manually set for a fixed
(static) configuration using the Dante Control-
ler software application. In the unfortunate
event that a specific Model 348’s IP address is
“lost,” the Address Resolution Protocol (ARP)
networking command can be used to “probe”
devices on a network for this information. For
example, in Windows OS the arp –a command
can be used to display a list of LAN information
that includes MAC addresses and correspond-
ing IP addresses. The simplest means of iden-
tifying an unknown IP address is to create a
“mini” LAN with a small PoE-enabled Ethernet
switch connecting a personal computer to the
Model 348. Then by using the appropriate ARP
command the required “clues” can be obtained.
Optimizing Network
Performance
For best Dante audio-over-Ethernet perfor-
mance a network that supports VoIP QoS
(voice-over-internet-protocol quality of service)
capability is recommended. This can typically
be implemented on virtually all contemporary
managed Ethernet switches. There are even
specialized switches that are optimized for
entertainment-associated applications. Refer
to the Audinate website (www.audinate.com)
for details on how to optimize a network for
Dante applications.
Button Labeling
The Model 348 provides eight pushbutton
switches that are associated with the eight talk
functions. The button covers are clear with a
white translucent lens underneath. As of the
time of writing this guide the factory doesn’t
have a recommended method as to how to
install custom labels underneath the button
caps. We have observed units where this has
been successfully implemented but exactly
how it was executed is not known. It’s pos-
sible that a button cap can be removed using
a gentle prying force on its bottom edge us-
ing a straight-blade screwdriver. An Xcelite®
“greenie” screwdriver, ubiquitous to the audio
and broadcast industry, might be appropriate.
Once a cap is removed a custom label could
be inserted between it and the translucent
lens. Then the cap could be “snapped” back
onto the body of the switch.
Additional Connector Location
A spare connector location, labeled A, is pro-
vided on the Model 348’s back panel. From
the factory it contains a blank plate that can
be removed and replaced with a variety of
“XLR-style” connectors. The spare connector
location is specifically included so that a Model
348 can be customized to meet the many
specific needs that arise in broadcast and
related audio applications. Expected uses
for this location include adding a 6- or 7-pin
XLR connector to allow direct connection of a
broadcast headset. Other uses include add-
ing a ¼-inch 3-conductor “stereo” headphone
output or creating a “mult” function for the DC
input connection. A number of interface cable
assemblies, along with some special function
kits, are available from Studio Technologies.
