Creating a Physical Dante NetworkA physical network is required to share Dante audio channels between a DMP 128 AT device and a NetPA AT The NetPA 502 AT and NetPA 1001-70V AT have an RJ-45 connector located on the back panel that accepts a standard network cable
A DMP 128-based Dante network can be configured in a star or daisy chain network topology using the four port switch and the Dante Controller in switched mode
Star network topology places one DMP 128 C AT as the central unit which connects directly to up to three more units Alternatively a larger network switch in place of the central DMP 128 AT allows more than four NetPA ATs to connect in the star configuration

Figure 5 Daisy Chain Topology
Hybrid versions combining the star and daisy chain topologies can be built but a ring topology or any topology that creates a duplicate connection causes a connection failure in Dante Controller
NOTE Connections between ports in either a star or daisy chain network do not need to be sequential (1 to 2 2 to 3 3 to 4) nor do they need to be made between the same port numbers (1 to 1 2 to 2 3 to 3 4 to 4)
NOTE At the moment Dante is not compatible with EEE (Energy Efficient Ethernet) technology Care should be taken when using a network switch with this technology in a Dante network
bull If using a managed switch ensure that it supports disabling EEE on all ports that will be used for Dante traffic
bull If using an unmanaged switch do not use models that support the EEE function as it can not be disabled on these models
bull For more information on this topic see the Audinate website
Resetting the NetPA ATThe NetPA AT utilizes DHCP addressing by default
A recessed reset button on the rear panel (see figure 1 G on page 1) initiates a reset mode Reset sets the IP addressing mode to DHCP (Dante default) clear the previous IP address and reset the device name to default
NOTE Initiating a reset while the NetPA AT is connected to a transmitting device severs that connection
To reset the NetPA AT press and hold down the reset button for ten seconds until both of the rear panel RJ-45 Ethernet port LEDs blink twice
NOTE When the NetPA AT is first powered on or reset the default name shall be ldquoNetPA-xxxxxxrdquo where xxxxxx are the last six digits or letters of the MAC address of the unit

Creating a Physical Dante NetworkA physical network is required to share Dante audio channels between a DMP 128 AT device and a NetPA AT The NetPA 502 AT and NetPA 1001-70V AT have an RJ-45 connector located on the back panel that accepts a standard network cable
A DMP 128-based Dante network can be configured in a star or daisy chain network topology using the four port switch and the Dante Controller in switched mode
Star network topology places one DMP 128 C AT as the central unit which connects directly to up to three more units Alternatively a larger network switch in place of the central DMP 128 AT allows more than four NetPA ATs to connect in the star configuration

Figure 5 Daisy Chain Topology
Hybrid versions combining the star and daisy chain topologies can be built but a ring topology or any topology that creates a duplicate connection causes a connection failure in Dante Controller
NOTE Connections between ports in either a star or daisy chain network do not need to be sequential (1 to 2 2 to 3 3 to 4) nor do they need to be made between the same port numbers (1 to 1 2 to 2 3 to 3 4 to 4)
NOTE At the moment Dante is not compatible with EEE (Energy Efficient Ethernet) technology Care should be taken when using a network switch with this technology in a Dante network
bull If using a managed switch ensure that it supports disabling EEE on all ports that will be used for Dante traffic
bull If using an unmanaged switch do not use models that support the EEE function as it can not be disabled on these models
bull For more information on this topic see the Audinate website
Resetting the NetPA ATThe NetPA AT utilizes DHCP addressing by default
A recessed reset button on the rear panel (see figure 1 G on page 1) initiates a reset mode Reset sets the IP addressing mode to DHCP (Dante default) clear the previous IP address and reset the device name to default
NOTE Initiating a reset while the NetPA AT is connected to a transmitting device severs that connection
To reset the NetPA AT press and hold down the reset button for ten seconds until both of the rear panel RJ-45 Ethernet port LEDs blink twice
NOTE When the NetPA AT is first powered on or reset the default name shall be ldquoNetPA-xxxxxxrdquo where xxxxxx are the last six digits or letters of the MAC address of the unit

Creating a Physical Dante NetworkA physical network is required to share Dante audio channels between a DMP 128 AT device and a NetPA AT The NetPA 502 AT and NetPA 1001-70V AT have an RJ-45 connector located on the back panel that accepts a standard network cable
A DMP 128-based Dante network can be configured in a star or daisy chain network topology using the four port switch and the Dante Controller in switched mode
Star network topology places one DMP 128 C AT as the central unit which connects directly to up to three more units Alternatively a larger network switch in place of the central DMP 128 AT allows more than four NetPA ATs to connect in the star configuration

Figure 5 Daisy Chain Topology
Hybrid versions combining the star and daisy chain topologies can be built but a ring topology or any topology that creates a duplicate connection causes a connection failure in Dante Controller
NOTE Connections between ports in either a star or daisy chain network do not need to be sequential (1 to 2 2 to 3 3 to 4) nor do they need to be made between the same port numbers (1 to 1 2 to 2 3 to 3 4 to 4)
NOTE At the moment Dante is not compatible with EEE (Energy Efficient Ethernet) technology Care should be taken when using a network switch with this technology in a Dante network
bull If using a managed switch ensure that it supports disabling EEE on all ports that will be used for Dante traffic
bull If using an unmanaged switch do not use models that support the EEE function as it can not be disabled on these models
bull For more information on this topic see the Audinate website
Resetting the NetPA ATThe NetPA AT utilizes DHCP addressing by default
A recessed reset button on the rear panel (see figure 1 G on page 1) initiates a reset mode Reset sets the IP addressing mode to DHCP (Dante default) clear the previous IP address and reset the device name to default
NOTE Initiating a reset while the NetPA AT is connected to a transmitting device severs that connection
To reset the NetPA AT press and hold down the reset button for ten seconds until both of the rear panel RJ-45 Ethernet port LEDs blink twice
NOTE When the NetPA AT is first powered on or reset the default name shall be ldquoNetPA-xxxxxxrdquo where xxxxxx are the last six digits or letters of the MAC address of the unit

Creating a Physical Dante NetworkA physical network is required to share Dante audio channels between a DMP 128 AT device and a NetPA AT The NetPA 502 AT and NetPA 1001-70V AT have an RJ-45 connector located on the back panel that accepts a standard network cable
A DMP 128-based Dante network can be configured in a star or daisy chain network topology using the four port switch and the Dante Controller in switched mode
Star network topology places one DMP 128 C AT as the central unit which connects directly to up to three more units Alternatively a larger network switch in place of the central DMP 128 AT allows more than four NetPA ATs to connect in the star configuration

Figure 5 Daisy Chain Topology
Hybrid versions combining the star and daisy chain topologies can be built but a ring topology or any topology that creates a duplicate connection causes a connection failure in Dante Controller
NOTE Connections between ports in either a star or daisy chain network do not need to be sequential (1 to 2 2 to 3 3 to 4) nor do they need to be made between the same port numbers (1 to 1 2 to 2 3 to 3 4 to 4)
NOTE At the moment Dante is not compatible with EEE (Energy Efficient Ethernet) technology Care should be taken when using a network switch with this technology in a Dante network
bull If using a managed switch ensure that it supports disabling EEE on all ports that will be used for Dante traffic
bull If using an unmanaged switch do not use models that support the EEE function as it can not be disabled on these models
bull For more information on this topic see the Audinate website
Resetting the NetPA ATThe NetPA AT utilizes DHCP addressing by default
A recessed reset button on the rear panel (see figure 1 G on page 1) initiates a reset mode Reset sets the IP addressing mode to DHCP (Dante default) clear the previous IP address and reset the device name to default
NOTE Initiating a reset while the NetPA AT is connected to a transmitting device severs that connection
To reset the NetPA AT press and hold down the reset button for ten seconds until both of the rear panel RJ-45 Ethernet port LEDs blink twice
NOTE When the NetPA AT is first powered on or reset the default name shall be ldquoNetPA-xxxxxxrdquo where xxxxxx are the last six digits or letters of the MAC address of the unit

A DMP 128-based Dante network can be configured in a star or daisy chain network topology using the four port switch and the Dante Controller in switched mode
Star network topology places one DMP 128 C AT as the central unit which connects directly to up to three more units Alternatively a larger network switch in place of the central DMP 128 AT allows more than four NetPA ATs to connect in the star configuration

Figure 5 Daisy Chain Topology
Hybrid versions combining the star and daisy chain topologies can be built but a ring topology or any topology that creates a duplicate connection causes a connection failure in Dante Controller
NOTE Connections between ports in either a star or daisy chain network do not need to be sequential (1 to 2 2 to 3 3 to 4) nor do they need to be made between the same port numbers (1 to 1 2 to 2 3 to 3 4 to 4)
NOTE At the moment Dante is not compatible with EEE (Energy Efficient Ethernet) technology Care should be taken when using a network switch with this technology in a Dante network
bull If using a managed switch ensure that it supports disabling EEE on all ports that will be used for Dante traffic
bull If using an unmanaged switch do not use models that support the EEE function as it can not be disabled on these models
bull For more information on this topic see the Audinate website
Resetting the NetPA ATThe NetPA AT utilizes DHCP addressing by default
A recessed reset button on the rear panel (see figure 1 G on page 1) initiates a reset mode Reset sets the IP addressing mode to DHCP (Dante default) clear the previous IP address and reset the device name to default
NOTE Initiating a reset while the NetPA AT is connected to a transmitting device severs that connection
To reset the NetPA AT press and hold down the reset button for ten seconds until both of the rear panel RJ-45 Ethernet port LEDs blink twice
NOTE When the NetPA AT is first powered on or reset the default name shall be ldquoNetPA-xxxxxxrdquo where xxxxxx are the last six digits or letters of the MAC address of the unit
