From the Dante Controller application menu, select 'Check for Updates'.
Checking for Updates Automatically
Dante Controller can also check for updates automatically. If an update becomes available, you will be notified via a
pop-up message. To activate automatic checking, in the update dialog, select the option to check for updates
automatically.
Networks and Switches
Special network infrastructure is not required for Dante AV network
Since Dante is based upon universally accepted networking standards, Dante-enabled devices can be connected using
inexpensive off-the-shelf Ethernet switches and cabling.
A dedicated network infrastructure is not required
for Dante AV network
Dante-enabled devices can happily coexist with other equipment making use of the network, such as general-purpose
PCs that is actively sending and receiving email and other data.
Selecting Cables
All Bolin Dante AV devices are designed to be used with gigabit transmission (1000BASE-T), so be sure to use a
CAT5e or higher network cable (you can use CAT6 and CAT7 cables as necessary).
Selecting Network Switches
You will need a network switch that meets the following requirements to construct a Dante network.
1. Gigabit ports for inter-switch connections
a.
All the ports are capable of simultaneous gigabit transfer, determine whether the switching capacity is
at least 1 Gbps × the number of ports × 2 (in and out)
2. Capable of switching off Energy Efficient Ethernet (EEE) and other power-saving features
a.
EEE (Energy Efficient Ethernet) is a technology that reduces switch power consumption during
periods of low network traffic. It is also sometimes known as Green Ethernet andIEEE802.3az.
Although power management should be negotiated automatically in switches that support EEE, it is a
relatively new technology, and some switches do not perform the negotiation properly. This may
cause EEE to be enabled in Dante networks when it is not appropriate, resulting in poor
synchronization performance and occasional dropouts.
3. We recommend managed (intelligent) switches that can be configured and monitored.
a.
So that you can adjust the switch settings according to the system requirements and monitor the status
of the switch. Simple systems can be operated using unmanaged switches (so long as they don’t use
EEE), but you will need to use a managed switch to construct a more stable Dante network.
4. We recommend switches that support DiffServ (DSCP) Quality of Service (QoS) with strict priority and 4
queues.
a.
Quality of Service (QoS) is a feature of managed switches, which ensures that certain types of
network packets (e.g., clock sync and audio packets) get preferential treatment and are "moved to the
front of the line" ahead of other traffic.
b. QoS is required when using Dante in networks that have 100Mbps devices and is optional in networks
with Gigabit devices. We recommend that QoS be enabled in all Dante networks to ensure proper
operation under all possible conditions.
c. By configuring the QoS settings recommended by Dante on a network switch, you can give Dante
clock synchronization top priority and give audio data the next highest priority over background data
traffic. This will ensure good system performance when you need to transfer non-Dante data over the
same network or when you transfer massive amounts of audio data
5. Packet control features such as VLANs and IGMP snooping.
a.
IGMP Snooping (highly recommended when using Dante AV)
6. When transferring data over long distances between switches, consider using switches that support fiber
optical modules such as SFPs and GBICs.
7. If PoE power is needed, the switch should support POE++, IEEE802.3bt Type 4 Class 6 on each port.
