Axia node’s analog inputs fed from an unbalanced
source where both pieces of equipment are tied to a
facility ground.
Alternatively, if both pieces of equipment are not
both tied to a common facility ground, both sides of the
shield must be connected. In this case the “-“ side of the
nodes inputs are tied to the shield of the RJ-45 plug as
follows:
Axia node’s inputs fed from a floating source, with no
facility ground in common with the Axia node.
Using Axia Nodes with Ethernet
Radios
Applies to Node Software v2.3.2a and higher
There are several changes and additions to Axia Au-
dio Nodes software beginning with v2.3.2a designed
to simplify the operation of STLs and audio snakes
using Axia nodes in conjunction with Ethernet Ra-
dios.
These additions include:
STL Slave and STL Snake modes on Clock Master
Priority options
IP Low Rate is now set as the default receive Clock
mode in the LW Clock Mode options field. (Note that
this setting only defines the RECEIVE type of stream.
It does not change the clock stream type when the
node is acting as the Master Clock. We recommend
that you do not change this setting.)
A Standard Stream Buffering option, which is set to
100ms as default. (Note that this setting should not
be adjusted unless advised otherwise by Axia Tech-
nical Support.)
A “Master/Sync” confidence tally is added to the
Router Selector Node display.
Using Axia Audio Nodes as snakes or STLs
Note that the setup options described below require
that Node Software v2.3.2a or higher must be in-
stalled to work correctly.
OPTION 1 - Using two nodes back to back without
an Ethernet switch
In this scenario, the clock sync mode will set the
Clock Rate to a Low Rate sync packet regardless
of the Livewire Clock Mode setting. This enables a
more stable SYNC mode, eliminating the need for an
Ethernet switch between the nodes handling QOS of
the clock sync signal.
Navigate to the “QOS” web pages of the Audio
Nodes you’ll be using. Determine which one will be
the master and which the slave, and set the new “STL
Snake” and “STL Slave” clock priority modes to the
appropriate values.
Typically, you will set the Clock Master Priority op-
tion on the Node located in the studio to “7 (Always
Master) STL Snake”. The Node on the remote end of
the link should be set to “0 - (Always Slave) STL”.
All stream types must be set to Standard streams.
