The Global Port transmit LED increases its duration in proportion
to volume of data being transmitted.
5.4.2 Bus connections
Interconnections between units are recommended to
use the appropriately coloured CAT6A cables. A typical
data flow is shown in Figure 4, for a healthy bus loop.
The standard CAT6A connections are:
•
2Mx Top port
<->
Unit top port
•
2Mx Bottom port
<->
Unit bottom port
•
Unit Bottom port
<->
Unit top port

5.4.2.1 Split loop
If the data bus is broken, then the Sonix 2Mx
automatically enters ‘split loop’ mode and transmits
system status and control data from both top and
bottom ports. It also supports receiving unit’s status/
control on both ports simultaneously.
Figure 5 - Split loop bus data fl ow
The only exception to this is the global bus which is not
capable of being a loop.
5.4.3 Audio
Audio is routed in a similar arrangement to the data
control flow. There are 2 complete loops with an input
and an output on each port. The typical audio flow is
shown in Figure 6, however this is changed with units
generating audio to be played over the PA/GA system.
Under these condition unit’s break both loops and inject
their audio onto the bus (see Figure 7).

Audio is not found on Beacon or Power buses due to the con-
nected units not utilising it.
5.4.4 Global bus
The global bus port (only the top port of global bus
is used, bottom is reserved for future expansion) is
used to communicate with the Sonix Administration
Software (SAS). This communication allows status data
reporting and configuration changes to be made to any
unit connected on the system. The 2Mx also forwards
all the control & status datagrams transmitted into the
2mx for use in Sonix Administration Software to show
the current status and to log events that happen on the
system.
