Networking
Because the device will not show up in the Shure Device
Discovery application, the IP address of the control
software must be recorded to access the server.
1. Record the IP address of the ANI.
2. Connect Port 4 of the ANI to the network.
Operating the Control Software over Wi-Fi
When operating the MXW control software over Wi-Fi,
it's important to set up the wireless router properly for
best performance. The MXW System employs several
standard-based protocols that rely on multicast. Wi-Fi treats
broadcast and multicast packets differently than general
packets for backward compatibility reasons. In some cases,
the Wi-Fi router will limit the multicast packet transmission
rate to a value that is too slow for GUI to properly operate.
Wi-Fi routers typically support 802.11b, 802.11a/g, and/
or 802.11n standards. By default, many Wi-Fi routers
are configured to allow older 802.11b devices to operate
over the network. In this configuration, these routers will
automatically limit the multicast data rates (or sometimes
referred to as 'basic rate', or 'management rate') to
1-2Mbps.
Dedicate a Device for Master Clock
Dante uses the IEEE 1588 Precision Time Protocol (PTP)
to automatically select one device as the master clock for
all Dante devices on the network. PTP ensures that all
devices are similarly clocked, which is critical for both audio
delivery over the network and time-synced RF transmission
over the wireless link. The master clock in an MXW System
is the first MXW access point that connects to the network.
If several connect simultaneously, the access point with
the lowest MAC address will be selected. Additional MXW
components on the same network synchronize (slave) to
this access point clock master.
Setting Latency
Latency is the amount of time for a signal to travel across
the system to the outputs of a device. To account for
variances in latency time between devices and channels,
Dante has a predetermined selection of latency settings.
When the same setting is selected, it ensures that all Dante
devices on the network are in sync.
The latency setting for Dante devices should be set
according to the number of switches in the network. The
MXW Audio Network Interface and Access Point both
include an internal switch chip, which counts as a switch.
For example, one network interface connected to an access
point equals two switches.

3. Use the Shure Web Device Discovery application to
open the control software of the ANI.
4. Go to the Preferences tab.
5. Under the Network panel, change Port 4 Mode to Uplink.
Note: A Wi-Fi connection can only be used for the
control software. Network audio cannot be transmitted
over Wi-Fi.
Tip: For larger wireless microphone configurations, it's
recommended to increase the multicast transmission
rate to provide adequate bandwidth to the MXW
control software.
Important: For best performance, use a Wi-Fi router that does not limit the multicast rate to 1-2
Mbps.
Shure recommends the following Wi-Fi router brands:
• Cisco
• Linksys
• Apple
When a master device shuts down or goes offline, the
system will automatically begin selecting another master.
During this selection time (up to 30 seconds), the entire
system will NOT pass audio.
If the network setup or building management requires that
devices are periodically shut down, you can manually select
an access point as the Preferred Master device from Dante
Controller software. This allows the installer to set up the
system to ensure that the master access point never shuts
down during events.
Use Audinate's Dante Controller software to change the
latency setting.
